Lifecycle Timeline
3DescriptionCVE.org
Papra is a minimalistic document management and archiving platform. Prior to version 26.5.0, an authenticated user who is a member of any organization can delete or rename tags belonging to a different organization, given the target tag's ID. The route handler verifies the caller's membership of the ":organizationId" in the URL, but the repository write filters on tag.id alone, so the URL-level org scope never reaches the database. This issue has been patched in version 26.5.0.
AnalysisAI
Improper authorization in Papra allows authenticated users to delete or rename tags belonging to other organizations. The vulnerability affects Papra versions before 26.5.0, where tag mutation endpoints fail to scope database operations to the organization in the URL. An attacker with low privileges and membership in any organization can modify or remove tags of a different organization by knowing the target tag's identifier.
