Vulnerability Page

Each vulnerability in a project has a vulnerability page containing details of the vulnerability, including:

• Description
• When it was detected
• Current status
• Available actions
• Linked issues
• Actions log
• Filename and line number of the vulnerability (if available)
• Severity

For vulnerabilities in the Common Vulnerabilities and Exposures (CVE) catalog you can also retrieve the following by using the GraphQL API:

• EPSS score
• KEV status

For details on how to retrieve this additional data, see vulnerability risk assessment data.

If the scanner determined the vulnerability to be a false positive, an alert message is included at the top of the vulnerability’s page.

Explaining a vulnerability

GitLab can help you with a vulnerability by using a large language model to:

• Summarize the vulnerability.
• Help developers and security analysts to understand the vulnerability, how it could be exploited, and how to fix it.
• Provide a suggested mitigation.

Vulnerability Explanation

Explain a vulnerability with GitLab Duo Vulnerability Explanation. Use the explanation to better understand a vulnerability and its possible mitigation.

Prerequisites:

• You must have the GitLab Ultimate subscription tier.
• Have a paid GitLab Duo Enterprise seat.
• GitLab Duo must be enabled for the group or instance.
• You must be a member of the project.
• The vulnerability must be from a SAST scanner.

To explain the vulnerability:

1. On the left sidebar, select Search or go to and find your project.
2. Select Secure > Vulnerability report.
3. Optional. To remove the default filters, select Clear ().
4. Above the list of vulnerabilities, select the filter bar.
5. In the dropdown list that appears, select Tool, then select all the values in the SAST category.
6. Select outside the filter field. The vulnerability severity totals and list of matching vulnerabilities are updated.
7. Select the SAST vulnerability you want explained.

8. Do one of the following:

   • Select the text below the vulnerability description that reads You can also use AI by asking GitLab Duo Chat to explain this vulnerability and a suggested fix.
   • In the upper right, from the Resolve with merge request dropdown list, select Explain vulnerability, then select Explain vulnerability.
   • Open GitLab Duo Chat and use the explain a vulnerability command by typing /vulnerability_explain.

The response is shown on the right side of the page.

On GitLab.com this feature is available. By default, it is powered by the Anthropic claude-3-haiku model. We cannot guarantee that the large language model produces results that are correct. Use the explanation with caution.

Data shared with third-party AI APIs for Vulnerability Explanation

The following data is shared with third-party AI APIs:

• Vulnerability title (which might contain the filename, depending on which scanner is used).
• Vulnerability identifiers.
• Filename.

Vulnerability Resolution

Use GitLab Duo Vulnerability resolution to automatically create a merge request that resolves the vulnerability. By default, it is powered by the Anthropic claude-3.5-sonnet model.

We can’t guarantee that the large language model produces correct results. You should always review the proposed change before merging it. When reviewing, check that:

• Your application’s existing functionality is preserved.
• The vulnerability is resolved in accordance with your organization’s standards.

Prerequisites:

• You must have the GitLab Ultimate subscription tier and GitLab Duo Enterprise.
• You must be a member of the project.
• The vulnerability must be a SAST finding from a supported analyzer:
  • Any GitLab-supported analyzer.
  • A properly integrated third-party SAST scanner that reports the vulnerability location and a CWE Identifier for each vulnerability.
• The vulnerability must be of a supported type.

To resolve the vulnerability:

1. On the left sidebar, select Search or go to and find your project.
2. Select Secure > Vulnerability report.
3. Optional. To remove the default filters, select Clear ().
4. Above the list of vulnerabilities, select the filter bar.
5. In the dropdown list that appears, select Activity, then select Vulnerability Resolution available in the GitLab Duo (AI) category.
6. Select outside the filter field. The vulnerability severity totals and list of matching vulnerabilities are updated.
7. Select the SAST vulnerability you want resolved.
   • A blue icon is shown next to vulnerabilities that support Vulnerability Resolution.
8. In the upper-right corner, select Resolve with AI. If this project is a public project be aware that creating an MR will publicly expose the vulnerablity and offered resolution. To create the MR privately, please create a private fork, and repeat this process.
9. Add an additional commit to the MR. This forces a new pipeline to run.
10. After the pipeline is complete, on the pipeline security tab, confirm that the vulnerability no longer appears.
11. On the vulnerability report, manually update the vulnerability.

A merge request containing the AI remediation suggestions is opened. Review the suggested changes, then process the merge request according to your standard workflow.

Provide feedback on this feature in issue 476553.

Supported vulnerabilities for Vulnerability Resolution

To ensure that suggested resolutions are high-quality, Vulnerability Resolution is available for a specific set of vulnerabilities. The system decides whether to offer Vulnerability Resolution based on the vulnerability’s Common Weakness Enumeration (CWE) identifier.

We selected the current set of vulnerabilities based on testing by automated systems and security experts. We are actively working to expand coverage to more types of vulnerabilities.

Troubleshooting

Vulnerability Resolution sometimes cannot generate a suggested fix. Common causes include:

• False positive detected: Before proposing a fix, the AI model assesses whether the vulnerability is valid. It may judge that the vulnerability is not a true vulnerability, or isn’t worth fixing.
  • This can happen if the vulnerability occurs in test code. Your organization might still choose to fix vulnerabilities even if they happen in test code, but models sometimes assess these to be false positives.
  • If you agree that the vulnerability is a false-positive or is not worth fixing, you should dismiss the vulnerability and select a matching reason.
    • To customize your SAST configuration or report a problem with a GitLab SAST rule, see SAST rules.
• Temporary or unexpected error: The error message may state that “an unexpected error has occurred”, “the upstream AI provider request timed out”, “something went wrong”, or a similar cause.
  • These errors may be caused by temporary problems with the AI provider or with GitLab Duo.
  • A new request may succeed, so you can try to resolve the vulnerability again.
  • If you continue to see these errors, contact GitLab for assistance.

Data shared with third-party AI APIs for Vulnerability Resolution

The following data is shared with third-party AI APIs:

• Vulnerability name
• Vulnerability description
• Identifiers (CWE, OWASP)
• Entire file that contains the vulnerable lines of code
• Vulnerable lines of code (line numbers)

Vulnerability Resolution in a merge request

Use GitLab Duo Vulnerability resolution to automatically create a merge request suggestion comment that resolves the vulnerability finding. By default, it is powered by the Anthropic claude-3.5-sonnet model.

To resolve the vulnerability finding:

1. On the left sidebar, select Search or go to and find your project.
2. Select Merge requests.
3. Select a merge request.
   • Vulnerability findings supported by Vulnerability Resolution are indicated by the tanuki AI icon ().
4. Select the supported findings to open the security finding dialog.
5. In the lower-right corner, select Resolve with AI.

A comment containing the AI remediation suggestions is opened in the merge request. Review the suggested changes, then apply the merge request suggestion according to your standard workflow.

  • If you continue to see these errors, contact GitLab for assistance.
• Resolution target could not be found in the merge request, unable to create suggestion:
  • This error may occur when the target branch has not run a full security scan pipeline. See the merge request documentation.

Vulnerability code flow

For specific types of vulnerabilities, GitLab Advanced SAST provides code flow information. A vulnerability’s code flow is the path the data takes from the user input (source) to the vulnerable line of code (sink), through all assignments, manipulation, and sanitization.

For details on how to view a vulnerability’s code flow, see Vulnerability code flow.

Vulnerability status values

A vulnerability’s status can be:

• Needs triage: The default state for a newly discovered vulnerability.
• Confirmed: A user has seen this vulnerability and confirmed it to be accurate.
• Dismissed: A user has evaluated this vulnerability and dismissed it. Dismissed vulnerabilities are ignored if detected in subsequent scans.
• Resolved: The vulnerability has been fixed or is no longer present. If a resolved vulnerability is reintroduced and detected again, its record is reinstated and its status set to Needs triage.

A vulnerability typically goes through the following lifecycle:

Vulnerability is no longer detected

A vulnerability may be no longer detected because of changes made deliberately to remediate it or as a side effect of other changes. When a security scan runs and a vulnerability is no longer detected in the default branch, the scanner adds No longer detected to the record’s activity log but the record’s status does not change. Instead you should check and confirm the vulnerability has been resolved and if so, manually change its status to Resolved. You can also use a vulnerability management policy to automatically change the status of vulnerabilities matching specific criteria to Resolved.

Vulnerability dismissal reasons

When you dismiss a vulnerability you must choose one of the following reasons:

• Acceptable risk: The vulnerability is known, and has not been remediated or mitigated, but is considered to be an acceptable business risk.
• False positive: An error in reporting in which a test result incorrectly indicates the presence of a vulnerability in a system when the vulnerability is not present.
• Mitigating control: The vulnerability’s risk is mitigated by a management, operational, or technical control (that is, safeguard or countermeasure) employed by an organization that provides equivalent or comparable protection for an information system.
• Used in tests: The finding is not a vulnerability because it is part of a test or is test data.
• Not applicable: The vulnerability is known, and has not been remediated or mitigated, but is considered to be in a part of the application that will not be updated.

Change the status of a vulnerability

Prerequisites:

• You must have at least the Maintainer role for the project, or a custom role with the admin_vulnerability permission.

To change a vulnerability’s status from its Vulnerability Page:

1. On the left sidebar, select Search or go to and find your project.
2. Select Secure > Vulnerability report.
3. Select the vulnerability’s description.

4. From the Status dropdown list select a status, then select Change status.

   In GitLab 15.11 and later, you must select a dismissal reason when you change a vulnerability’s status to Dismissed.

5. Optionally, at the bottom of the page, add a comment to the log entry.

Details of the status change, including who made the change and when, are recorded in the vulnerability’s action log.

Create a GitLab issue for a vulnerability

You can create a GitLab issue to track any action taken to resolve or mitigate a vulnerability. To create a GitLab issue for a vulnerability:

1. On the left sidebar, select Search or go to and find your project.
2. Select Secure > Vulnerability report.
3. Select the vulnerability’s description.
4. Select Create issue.

The issue is created in the GitLab project with information from the vulnerability report.

To create a Jira issue, see Create a Jira issue for a vulnerability.

Linking a vulnerability to GitLab and Jira issues

You can link a vulnerability to one or more existing GitLab or Jira issues. Only one linking feature is available at the same time. Adding a link helps track the issue that resolves or mitigates a vulnerability.

Link a vulnerability to existing GitLab issues

Prerequisites:

• Jira issues integration must not be enabled.

To link a vulnerability to existing GitLab issues:

1. On the left sidebar, select Search or go to and find your project.
2. Select Secure > Vulnerability report.
3. Select the vulnerability’s description.
4. In the Linked issues section, select the plus icon ().
5. For each issue to be linked, either:
   • Paste a link to the issue.
   • Enter the issue’s ID (prefixed with a hash #).
6. Select Add.

The selected GitLab issues are added to the Linked items section, and the linked issues counter is updated.

GitLab issues linked to a vulnerability are shown in the Vulnerability Report and the vulnerability’s page.

Be aware of the following conditions between a vulnerability and a linked GitLab issue:

• The vulnerability page shows related issues, but the issue page doesn’t show the vulnerability it’s related to.
• An issue can only be related to one vulnerability at a time.
• Issues can be linked across groups and projects.

Link a vulnerability to existing Jira issues

Prerequisites:

• Ensure the Jira issues integration is configured and the Create Jira issues for vulnerabilities checkbox is selected.

To link a vulnerability to existing Jira issues, add the following line to the Jira issue’s description:

/-/security/vulnerabilities/<id>

<id> is any vulnerability ID. You can add several lines with different IDs to one description.

Jira issues with appropriate description are added to the Related Jira issues section, and the linked issues counter is updated.

Jira issues linked to a vulnerability are shown only on the vulnerability page.

Be aware of the following conditions between a vulnerability and a linked Jira issue:

• The vulnerability page and the issue page show the vulnerability they are related to.
• An issue can be related to one or more vulnerabilities at the same time.

Resolve a vulnerability

For some vulnerabilities a solution is already known but needs to be implemented manually. The Solution field in the Vulnerability page is provided by the security scanning tool that reported the security finding, or entered during the manual creation of a vulnerability. The GitLab tools utilize information from the GitLab Advisory Database.

Additionally, some tools may include a software patch to apply the suggested solution. In those instances, a vulnerability’s page includes a Resolve with merge request option.

The following scanners are supported by this feature:

• Dependency Scanning. Automatic patch creation is only available for Node.js projects managed with yarn. Also, Automatic patch creation is only supported when FIPS mode is disabled.
• Container Scanning.

To resolve a vulnerability, you can either:

• Resolve a vulnerability with a merge request.
• Resolve a vulnerability manually.

Resolve a vulnerability with a merge request

To resolve the vulnerability with a merge request:

1. On the left sidebar, select Search or go to and find your project.
2. Select Secure > Vulnerability report.
3. Select the vulnerability’s description.
4. From the Resolve with merge request dropdown list, select Resolve with merge request.

A merge request is created which applies the patch required to resolve the vulnerability. Process the merge request according to your standard workflow.

Resolve a vulnerability manually

To manually apply the patch that GitLab generated for a vulnerability:

1. On the left sidebar, select Search or go to and find your project.
2. Select Secure > Vulnerability report.
3. Select the vulnerability’s description.
4. From the Resolve with merge request dropdown list, select Download patch to resolve.
5. Ensure your local project has the same commit checked out that was used to generate the patch.
6. Run git apply remediation.patch.
7. Verify and commit the changes to your branch.
8. Create a merge request to apply the changes to your main branch.
9. Process the merge request according to your standard workflow.

Enable security training for vulnerabilities

Security training helps your developers learn how to fix vulnerabilities. Developers can view security training from selected educational providers, relevant to the detected vulnerability.

To enable security training for vulnerabilities in your project:

1. On the left sidebar, select Search or go to and find your project.
2. Select Secure > Security configuration.
3. On the tab bar, select Vulnerability Management.
4. To enable a security training provider, turn on the toggle.

Each integration submits the Vulnerability identifier, for example CWE or OWASP, and the language to the security training vendor. The resulting link to the vendor training is what appears in a GitLab Vulnerability.

View security training for a vulnerability

The vulnerability page may include a training link relevant to the detected vulnerability if security training is enabled. The availability of training depends on whether the enabled training vendor has content matching the particular vulnerability. Training content is requested based on the vulnerability identifiers. The identifier given to a vulnerability varies from one vulnerability to the next and the available training content varies between vendors. Some vulnerabilities do not display training content. Vulnerabilities with a CWE are most likely to return a training result.

To view the security training for a vulnerability:

1. On the left sidebar, select Search or go to and find your project.
2. Select Secure > Vulnerability report.
3. Select the vulnerability for which you want to view security training.
4. Select View training.
