CVE-2026-44718: CWE-639: Authorization Bypass Through User-Controlled Key in mathesar-foundation mathesar
Mathesar is a web application that makes working with PostgreSQL databases both simple and powerful. From 0.2.0 to before 0.10.0, explorations.get, explorations.replace, and explorations.delete operate on an exploration_id without verifying that the requesting user was a collaborator on the exploration’s database. An authenticated user on the same Mathesar installation who knew or guessed an exploration ID could read, replace, or delete a saved exploration belonging to a database where they were not a collaborator. This affected Mathesar-managed saved exploration definitions, including names, descriptions, selected columns, display metadata, filters, sorting, and transformations. This vulnerability is fixed in 0.10.0.
AI Analysis
Technical Summary
Mathesar is a web application for managing PostgreSQL database explorations. Versions 0.2.0 through before 0.10.0 have a flaw where the API endpoints explorations.get, explorations.replace, and explorations.delete do not verify that the requesting user is a collaborator on the target exploration's database. This allows an authenticated user who knows or can guess an exploration ID to read, modify, or delete exploration data they should not have access to. The vulnerability affects saved exploration metadata and configuration. The issue is resolved in version 0.10.0.
Potential Impact
An authenticated user on the same Mathesar installation can bypass authorization controls to access or modify exploration data for databases where they lack collaboration rights. This could lead to unauthorized disclosure, alteration, or deletion of saved exploration definitions, potentially impacting data integrity and confidentiality within the application context.
Mitigation Recommendations
Upgrade Mathesar to version 0.10.0 or later, where this authorization bypass vulnerability is fixed. No other official remediation or temporary fixes are documented. Patch status is confirmed by the vendor's versioning information.
