CVE-2025-64497 — Tuleap exposes releases for all projects to File Release System project administrators

Tuleap is an Open Source Suite for management of software development and collaboration. Versions below 17.0.99.1762431347 of Tuleap Community Edition and Tuleap Enterprise Edition below 17.0-2, 16.13-7 and 16.12-10 allow attackers to access file release system information in projects they do not have access to. This issue is fixed in version 17.0.99.1762431347 of the Tuleap Community Edition and versions 17.0-2, 16.13-7 and 16.12-10 of Tuleap Enterprise Edition.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.3% (30-day exploitation probability)+3
  • Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

  • Documented patch — github.com (NIST National Vulnerability Database)
  • Documented patch — tuleap.net (NIST National Vulnerability Database)

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Enalean Tuleap).
  2. Apply the fixed version or the patch documented under Remediation.
  3. Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.

What should defenders know first?

CVE-2025-64497 is "Tuleap exposes releases for all projects to File Release System project administrators", rated Medium. It affects Tuleap (Enalean); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 6.5 describes technical severity. EPSS 0.28% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
