CVE-2025-22129 Overview
CVE-2025-22129 affects Tuleap, an open source suite for managing software development and collaboration. The vulnerability allows an unauthorized user to access restricted information within affected instances. The issue is classified under [CWE-280] (Improper Handling of Insufficient Permissions or Privileges) and requires low-privileged network access to exploit. Enalean addressed the flaw in Tuleap Community Edition 16.3.99.1736242932, Tuleap Enterprise Edition 16.2-5, and Tuleap Enterprise Edition 16.3-2. No workarounds exist, so administrators must upgrade to remediate exposure.
Critical Impact
Authenticated users with low privileges can retrieve information they should not be authorized to view, breaching confidentiality boundaries within Tuleap projects.
Affected Products
- Tuleap Community Edition prior to 16.3.99.1736242932
- Tuleap Enterprise Edition prior to 16.2-5
- Tuleap Enterprise Edition prior to 16.3-2

Technical Details for CVE-2025-22129
Vulnerability Analysis
CVE-2025-22129 is an improper access control weakness in Tuleap that permits unauthorized retrieval of restricted information. The flaw sits within Tuleap's permission enforcement layer, where certain resource requests are not adequately validated against the requester's privilege level. An authenticated attacker with a standard Tuleap account can exercise the flawed code path over the network without user interaction. Confidentiality is affected, while integrity and availability of the platform remain intact. The current EPSS probability of 0.333% (percentile 26.038) suggests low near-term exploitation activity, but the network-reachable nature of the flaw warrants prompt remediation.
Root Cause
The root cause is insufficient permission checks on a resource retrieval path within Tuleap, categorized as [CWE-280]. When a low-privileged user requests specific project or tracker artifacts, the application returns data without confirming the caller holds the required access rights. The upstream fix is committed in the Tuleap repository under commit 3edf8158ba40be66f0b661888b8b2805784795d1, which restores the missing authorization enforcement.
Attack Vector
Exploitation requires network reachability to a Tuleap instance and a valid low-privilege account. An attacker issues crafted requests to the vulnerable endpoint and receives restricted content in the response. No social engineering or elevated privileges are required, and the attack complexity is low. For a technical description of the affected code path, see the GitHub Security Advisory GHSA-f34g-wc2m-mf76 and the Tuleap tracker entry.
No verified public exploit code is available for this vulnerability, so a prose description is provided in place of a proof of concept.
Detection Methods for CVE-2025-22129
Indicators of Compromise
- Unexpected access requests from low-privileged accounts to Tuleap project, tracker, or artifact endpoints they do not normally interact with.
- HTTP 200 responses containing artifact identifiers or project metadata returned to users lacking membership in the associated project.
- Elevated request volumes to Tuleap REST endpoints from single authenticated sessions enumerating resource IDs.
Detection Strategies
- Review Tuleap application logs for authenticated sessions accessing resources outside their assigned project scope.
- Correlate user role assignments with resource access patterns to identify permission boundary violations.
- Baseline normal artifact and tracker access per user role, then alert on deviations that suggest enumeration.
Monitoring Recommendations
- Enable verbose access logging on Tuleap web and REST endpoints and forward events to a central SIEM.
- Monitor for sequential ID enumeration patterns against /plugins/tracker/ and related project resource paths.
- Alert on privilege-boundary anomalies where standard users retrieve data belonging to restricted projects.
How to Mitigate CVE-2025-22129
Immediate Actions Required
- Upgrade Tuleap Community Edition to 16.3.99.1736242932 or later.
- Upgrade Tuleap Enterprise Edition to 16.2-5 or 16.3-2 or later, depending on the deployed branch.
- Audit existing Tuleap user accounts and revoke unnecessary access for users who no longer require project membership.
- Review access logs since the vulnerability window to identify potential unauthorized data retrieval.
Patch Information
Enalean has released fixed builds addressing CVE-2025-22129. The corrective change is tracked in commit 3edf8158ba40be66f0b661888b8b2805784795d1, referenced in the Tuleap commit details. Administrators should apply the vendor-supplied packages for their edition and verify version numbers after upgrade.
Workarounds
- No workarounds are available. Upgrading to a patched Tuleap release is the only supported remediation per the vendor advisory.
- As a compensating control until patching completes, restrict Tuleap network exposure to trusted networks or VPN users.
# Verify installed Tuleap version after upgrade
rpm -q tuleap
# Expected output should list a version at or above the fixed release
