CVE-2025-50179 Overview
CVE-2025-50179 is a Cross-Site Request Forgery (CSRF) vulnerability affecting Tuleap, an open source suite for software development management and collaboration. The flaw allows an attacker to trick authenticated victims into unknowingly modifying canned responses within the application. Tuleap Community Edition versions prior to 16.8.99.1749830289 and Tuleap Enterprise Edition versions prior to 16.9-1 are affected. The vulnerability is tracked under [CWE-352] and requires user interaction to exploit.
Critical Impact
An attacker can leverage a crafted web page or link to alter canned responses in a target Tuleap instance, tampering with content integrity when a logged-in user visits attacker-controlled content.
Affected Products
- Enalean Tuleap Community Edition prior to 16.8.99.1749830289
- Enalean Tuleap Enterprise Edition prior to 16.9-1

Technical Details for CVE-2025-50179
Vulnerability Analysis
The vulnerability is a Cross-Site Request Forgery weakness in Tuleap's canned response management functionality. Canned responses are pre-written text templates used within tracker workflows to speed up user replies. Because the request that updates a canned response lacks sufficient anti-CSRF protection, an attacker can craft a malicious page that submits a state-changing request on behalf of an authenticated victim. The impact is limited to integrity of canned response content, with no direct confidentiality or availability consequences.
Root Cause
The underlying issue is a missing or insufficient CSRF token verification on the endpoint responsible for modifying canned responses. Tuleap did not adequately validate that the state-changing request originated from a legitimate, authenticated session flow. This mapping aligns with [CWE-352] Cross-Site Request Forgery, where server-side controls do not distinguish between forged and genuine requests.
Attack Vector
Exploitation requires a network-accessible Tuleap instance and an authenticated victim who visits attacker-controlled content. The attacker hosts a page that automatically submits a crafted HTTP request to the vulnerable Tuleap endpoint. When the victim's browser sends the request with valid session cookies, the server processes the change as if the victim intended it. No credentials are required from the attacker; only the victim's active session and interaction with the malicious content are needed.
No public proof-of-concept exploit code is available. Refer to the GitHub Security Advisory GHSA-rxpm-g7gw-4mrv and the upstream patch commit for technical details.
Detection Methods for CVE-2025-50179
Indicators of Compromise
- Unexpected modifications to canned response text or titles within Tuleap trackers, especially those not authored by the account owner.
- HTTP referer values pointing to external, untrusted domains on requests that update canned responses.
- Audit log entries showing canned response changes correlated with user browsing activity to third-party sites.
Detection Strategies
- Enable and review Tuleap application audit logs for canned response create, update, and delete actions.
- Correlate web proxy or reverse proxy logs against Tuleap POST endpoints to identify cross-origin submissions.
- Alert on canned response changes performed within seconds of a user session receiving external referer traffic.
Monitoring Recommendations
- Monitor for anomalous request patterns to Tuleap tracker administration URLs from unexpected referers.
- Track user-agent and origin header consistency across authenticated Tuleap sessions to detect forged requests.
- Retain HTTP access logs long enough to reconstruct request chains during incident investigations.
How to Mitigate CVE-2025-50179
Immediate Actions Required
- Upgrade Tuleap Community Edition to version 16.8.99.1749830289 or later without delay.
- Upgrade Tuleap Enterprise Edition to version 16.9-1 or later without delay.
- Review recent canned response changes and revert any unauthorized modifications identified through audit logs.
Patch Information
Enalean released fixes in Tuleap Community Edition 16.8.99.1749830289 and Tuleap Enterprise Edition 16.9-1. The patch is documented in the GitHub commit 0f9aab6 and tracked in the Tuleap Tracker entry 43357.
Workarounds
- Instruct privileged Tuleap users to log out of the application when not actively using it to reduce session exposure.
- Restrict Tuleap administrative access to trusted network segments through reverse proxy or firewall controls.
- Deploy browser-side protections and enforce SameSite cookie policies at the proxy layer where feasible.
# Configuration example: verify installed Tuleap version and apply upgrade
rpm -q tuleap
yum update tuleap
systemctl restart tuleap
