CVE-2026-44733: CWE-620: Unverified Password Change in opf openproject
OpenProject is open-source, web-based project management software. Prior to 17.3.2 and 17.4.0, Business Logic Error on OpenProject through PATCH request to /api/v3/users/me permits to bypass password requirements. A password validation flaw in the change password behavior allows attackers to change a user's password only with an active session takeover. This vulnerability is fixed in 17.3.2 and 17.4.0.
AI Analysis
Technical Summary
CVE-2026-44733 is a business logic error in OpenProject's password change functionality. Specifically, before versions 17.3.2 and 17.4.0, an attacker who has taken over an active session can bypass password validation controls by sending a PATCH request to the /api/v3/users/me endpoint, allowing them to change the user's password without meeting the usual password requirements. This vulnerability is addressed in OpenProject versions 17.3.2 and 17.4.0.
Potential Impact
An attacker with an active session can change the password of the compromised user account without satisfying password complexity or validation rules. This could lead to account takeover persistence and potentially escalate impact depending on the privileges of the affected user. The vulnerability does not allow unauthenticated attackers to change passwords, limiting the attack vector to session takeover scenarios.
Mitigation Recommendations
Upgrade OpenProject to version 17.3.2 or 17.4.0 or later, where this vulnerability is fixed. Since this is a business logic flaw requiring an active session, ensure sessions are protected and monitored. Patch status is confirmed fixed in these versions. No other vendor advisories or temporary mitigations are indicated.
