CVE-2025-54877 — Tuleap's special and always there fields permissions are not verified in cross-tracker search

Tuleap is an Open Source Suite created to facilitate management of software development and collaboration. In Tuleap Community Edition versions before 16.10.99.1754050155 and Tuleap Enterprise Edition versions before 16.9-8 and before 16.10-5, an attacker can access to the content of the special and always there fields of accessible artifacts even if the permissions associated with the underlying fields do not allow it. This issue has been fixed in Tuleap Community Edition version 16.10.99.1754050155 and Tuleap Enterprise Edition versions 16.9-8 and 16.10-5.

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)+4
  • Technical severity (medium)+3
  • Automatable exploitation (SSVC)+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)

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. The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
  3. Apply the fixed version or the patch documented under Remediation.
  4. Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.

What should defenders know first?

CVE-2025-54877 is "Tuleap's special and always there fields permissions are not verified in cross-tracker search", 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 5.3 describes technical severity. EPSS 0.31% 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.
