CVE-2026-44733
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedOpenProject 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceOpenProject contains a business logic error in the PATCH /api/v3/users/me endpoint that allows bypassing password requirements during password change operations. An attacker with an active session takeover can exploit this validation flaw to change a user's password without proper validation.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm OpenProject is installedCheck for OpenProject installation by searching for its process (e.g., 'ps aux | grep -i openproject') or by accessing the web application on its known port (usually 80/443)Affected if OpenProject is running in the environment
-
Determine the installed OpenProject versionRun 'openproject --version' from the command line, or access the web UI footer which often displays the version, or check the package manager if installed via apt/yumAffected if The installed version is earlier than 17.3.2, or between 17.3.2 and 17.4.0 (exclusive of 17.4.0)
-
Verify the API v3 endpoint is accessibleAttempt a GET request to /api/v3/users/me using curl or a browser while authenticated, or check if the API responds to unauthenticated requestsAffected if The /api/v3/users/me endpoint is reachable and accepts requests
-
Review authentication logs for password change operationsCheck OpenProject logs (typically in /var/log/openproject or the log/ directory) for PATCH or PUT requests to /api/v3/users/me that involve password fields, look for timestamps and source IPsAffected if There are password change API requests that bypass normal validation patterns
-
Audit session management and token activityCheck the sessions table in the OpenProject database, or review application logs for concurrent session takeovers or suspicious session token usageAffected if Multiple sessions exist for the same user or session tokens show unusual activity patterns
The environment is affected if OpenProject is running with a version earlier than 17.3.2 or between 17.3.2 and 17.4.0, and the API v3 endpoint is accessible for authenticated users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade to OpenProject version 17.3.2 or 17.4.0 to receive the patch. Additionally, monitor for unauthorized password change events and enforce session security to limit the prerequisite for exploitation.
17.3.2 or 17.4.0 (whichever is newer in your release branch)
- Upgrade OpenProject to version 17.3.2 or higher
- Alternatively, upgrade to version 17.4.0 or higher
- Verify the upgrade by checking the OpenProject version after installation
- Test the password change functionality via PATCH /api/v3/users/me to confirm the vulnerability is resolved
