CVE-2026-18258: CWE-639: Authorization Bypass Through User-Controlled Key in Scripta eScriptorium
CVE-2026-18258 is an authorization bypass vulnerability in Scripta/eScriptorium version 26.04.1 and earlier. It affects several API endpoints, allowing a remote authenticated user to read, modify, and delete transcription content belonging to other users by manipulating primary keys in the request body. This occurs because the application queries a global model manager instead of a request-scoped queryset, bypassing proper authorization checks.
AI Analysis
Technical Summary
This vulnerability (CWE-639) in Scripta/eScriptorium allows an authenticated user to bypass authorization controls on the Line, LineTranscription, VirtualCollection, tag, and process API endpoints. The flaw arises from the use of primary keys supplied in the request body that are checked against a global model manager rather than a request-scoped queryset, enabling unauthorized access and modification of other users' transcription data.
Potential Impact
An attacker with valid authentication can read, modify, and delete transcription content of other users, leading to potential data confidentiality, integrity, and availability breaches. The CVSS v3.1 score of 8.8 reflects high severity with network attack vector, low attack complexity, and no user interaction required.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround has been documented at this time.
