Since 11.9 EXIF data are automatically stripped from JPG or TIFF image uploads. Because EXIF data may contain sensitive information (e.g. GPS location), you can remove EXIF data also from existing images which were uploaded before with the following command:
sudo RAILS_ENV=production -u git -H bundle exec rake gitlab:uploads:sanitize:remove_exif
This command by default runs in dry mode and it doesn’t remove EXIF data. It can be used for checking if (and how many) images should be sanitized.
The rake task accepts following parameters.
|integer||Only uploads with equal or greater ID will be processed|
|integer||Only uploads with equal or smaller ID will be processed|
|boolean||Do not remove EXIF data, only check if EXIF data are present or not, default: true|
|float||Pause for number of seconds after processing each image, default: 0.3 seconds|
|string||Run sanitization only for uploads of the given uploader (|
|date||Run sanitization only for uploads newer than given date (e.g. |
If you have too many uploads, you can speed up sanitization by setting
sleep_time to a lower value or by running multiple rake tasks in parallel,
each with a separate range of upload IDs (by setting
To run the command without dry mode and remove EXIF data from all uploads, you can use:
sudo RAILS_ENV=production -u git -H bundle exec rake gitlab:uploads:sanitize:remove_exif[,,false,] 2>&1 | tee exif.log
To run the command without dry mode on uploads with ID between 100 and 5000 and pause for 0.1 second, you can use:
sudo RAILS_ENV=production -u git -H bundle exec rake gitlab:uploads:sanitize:remove_exif[100,5000,false,0.1] 2>&1 | tee exif.log
Because the output of commands will be probably long, the output is written also into exif.log file.
If sanitization fails for an upload, an error message should be in the output of the rake task (typical reasons may
be that the file is missing in the storage or it’s not a valid image). Please
report any issues at
gitlab.com and use
prefix ‘EXIF’ in issue title with the error output and (if possible) the image.
