CVE-2026-48052: CWE-639: Authorization Bypass Through User-Controlled Key in papra-hq papra
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.
AI Analysis
Technical Summary
CVE-2026-48052 is an authorization bypass vulnerability in papra-hq's papra platform affecting versions before 26.5.0. The vulnerability arises because the route handler verifies user membership against the organization ID in the URL, but the database repository filters only by tag ID, ignoring organization scope. This allows an authenticated user from one organization to delete or rename tags belonging to another organization if they know the tag's ID. The flaw was addressed and patched in papra version 26.5.0.
Potential Impact
An authenticated user with membership in any organization can improperly modify or delete tags belonging to other organizations, leading to unauthorized integrity loss of tag data. The vulnerability does not impact confidentiality but affects integrity and availability of tag resources within the platform.
Mitigation Recommendations
Upgrade papra to version 26.5.0 or later, where this authorization bypass vulnerability has been patched. No other mitigation or temporary workaround is documented.
