CVE-2026-18258: CWE-639: Authorization Bypass Through User-Controlled Key in Scripta eScriptorium
Authorization bypass in the Line, LineTranscription, VirtualCollection, tag and process API endpoints in Scripta/eScriptorium through 26.04.1 allows a remote authenticated user to read, modify and delete other users' transcription content via primary keys supplied in the request body, which are queried against the global model manager instead of the request-scoped queryset
AI Analysis
Technical Summary
This vulnerability (CVE-2026-18258) in Scripta/eScriptorium involves authorization bypass through user-controlled keys in the Line, LineTranscription, VirtualCollection, tag, and process API endpoints. Authenticated users can supply primary keys in requests that are validated against a global model manager rather than a scoped queryset limited to their own data. This allows them to access and manipulate transcription content of other users remotely. The CVSS 3.1 score is 8.8, indicating high severity with network attack vector, low attack complexity, and no user interaction required.
Potential Impact
An authenticated attacker can read, modify, and delete transcription content of other users, potentially leading to data loss, unauthorized data disclosure, and integrity violations within the eScriptorium platform.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary mitigation has been documented at this time. Until a patch is available, restrict access to trusted users and monitor for suspicious activity related to the affected API endpoints.
