Summary

CVE-2025-13929 is a high-severity Allocation of Resources Without Limits or Throttling (CWE-770) vulnerability in Gitlab Gitlab. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 18.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SC-5 (Denial-of-service Protection) and SC-6 (Resource Availability).

Deeper analysis

CVE-2025-13929 is a denial-of-service vulnerability in GitLab Community Edition (CE) and Enterprise Edition (EE), affecting all versions from 10.0 prior to 18.7.6, 18.8 prior to 18.8.6, and 18.9 prior to 18.9.2. The flaw enables an unauthenticated user to trigger a DoS by issuing specially crafted requests to repository archive endpoints under certain conditions. It carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) and maps to CWE-770 (Allocation of Resources Without Limits or Throttling).

An unauthenticated attacker with network access can exploit this vulnerability with low attack complexity, no required privileges, and no user interaction. Exploitation causes high-impact disruption to service availability on the affected GitLab instance, without affecting confidentiality or integrity.

GitLab has remediated the issue via patches in versions 18.7.6, 18.8.6, and 18.9.2, as detailed in the March 11, 2026 patch release notes for 18.9.2. Administrators should prioritize upgrading to these fixed versions; further technical details are available in the associated GitLab issue tracker (gitlab.com/gitlab-org/gitlab/-/issues/582738) and HackerOne report (hackerone.com/reports/3441004).

Related Threats

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1499.004 Application or System Exploitation Impact
Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.
Why these techniques?

Unauthenticated network exploitation of public GitLab web endpoints directly matches T1190; resulting availability impact via application flaw matches T1499.004.
