Summary

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.
