### Impact Harbor fails to validate the user permissions when updating tag retention policies. API call: PUT /retentions/{id} By sending a request to update a tag retention policy with an id that belongs to a project that the currently authenticated user doesn’t have access to, the attacker could modify tag retention policies configured in other projects. ### Patches This and similar issues are fixed in Harbor v2.5.2 and later. Please upgrade as soon as possible. ### Workarounds There are no workarounds available. ### For more information If you have any questions or comments about this advisory: * Open an issue in [the Harbor GitHub repository](https://github.com/goharbor/harbor) ### Credits Thanks to [Gal Goldstein](https://www.linkedin.com/in/gal-goldshtein/) and [Daniel Abeles](https://www.linkedin.com/in/daniel-abeles/) from [Oxeye Security](https://www.oxeye.io/) for reporting this issue.
