CVE-2026-56679: CWE-915: Improperly Controlled Modification of Dynamically-Determined Object Attributes in decolua 9router
CVE-2026-56679 affects decolua 9router versions prior to 0.5.4. The vulnerability allows an authenticated user to modify security-critical settings via the PATCH /api/settings endpoint because the request body is written to persistent settings without a field whitelist. This can disable authentication for the entire application, exposing protected routes to unauthenticated access. The issue is fixed in version 0.5.4.
AI Analysis
Technical Summary
In decolua 9router before version 0.5.4, the PATCH /api/settings endpoint improperly controls modification of dynamically-determined object attributes by writing the entire request body to persistent settings without restricting which fields can be modified. This allows an authenticated user to set sensitive fields such as requireLogin, effectively disabling authentication and exposing protected API routes like /api/keys and /api/providers to unauthenticated users. The vulnerability is tracked as CWE-915 and has a CVSS 4.0 score of 8.7 (high severity). The issue is resolved in version 0.5.4.
Potential Impact
An authenticated user can disable authentication for the entire 9router application by modifying security-critical settings, leading to unauthorized access to protected routes and sensitive data. This compromises the confidentiality and integrity of the application’s security controls.
Mitigation Recommendations
Upgrade to decolua 9router version 0.5.4 or later, where this vulnerability is fixed. No other mitigation is indicated or required.
