The manipulation of the argument organizationId/tag.id with an unknown input leads to a privileges management vulnerability. CWE is classifying the issue as CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-48052 since 05/20/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1068 for this issue.
