AI Analysis
Technical Summary
CVE-2026-44733 is a business logic error in OpenProject's password change functionality. Before versions 17.3.2 and 17.4.0, an attacker who has taken over a user's active session can bypass password validation requirements when issuing a PATCH request to the /api/v3/users/me endpoint, allowing them to change the user's password without meeting normal password constraints. This vulnerability is classified under CWE-620 (Unverified Password Change).
Potential Impact
An attacker with an active session can change the password of the compromised user without satisfying password requirements, potentially locking out the legitimate user or escalating access. The vulnerability impacts confidentiality (high), integrity (low), and does not affect availability. Exploitation requires an active session and low privileges.
Mitigation Recommendations
This vulnerability is fixed in OpenProject versions 17.3.2 and 17.4.0. Users should upgrade to one of these versions or later to remediate the issue. No vendor advisory or patch link is provided, but the fix is confirmed in the version history. Until upgraded, users should ensure session security to prevent session takeover.
