Deeper analysis

CVE-2024-2454 is a denial-of-service vulnerability in GitLab Community Edition and Enterprise Edition. It affects all versions from 15.11 prior to 16.9.7, from 16.10 prior to 16.10.5, and from 16.11 prior to 16.11.2. The flaw resides in the pins endpoint, which can be abused via a crafted request to trigger resource exhaustion, corresponding to CWE-770 and carrying a CVSS 3.1 score of 6.5.

An authenticated attacker with low-privileged network access can send a specially formed request to the pins endpoint, resulting in high availability impact without affecting confidentiality or integrity. The attack requires no user interaction and can be performed remotely over the network.

Public references, including the GitLab issue tracker and associated HackerOne reports, point to the availability of patched releases that remediate the issue by updating to the fixed versions listed above.

EPSS for this CVE rose from a low baseline to a peak of 0.0887 on 2025-12-11 before receding to the current value of 0.0156, indicating a period of increased exploitation interest after disclosure.

Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-770

This control implements explicit throttling on session allocation, addressing the weakness of allocating resources without limits.

addresses: CWE-770

Plan testing exercises resource allocation limits and throttling during simulated failures, directly addressing weaknesses that allow unbounded resource use.

addresses: CWE-770

Contingency plan updates ensure recovery strategies address unbounded resource allocation, making it harder for attackers to exploit lack of throttling to cause prolonged outages.

addresses: CWE-770

Provides continuity when unbounded resource allocation at the primary site leads to exhaustion and downtime.

addresses: CWE-770

Alternate services allow operations to continue when primary allocation of resources lacks limits or throttling.

addresses: CWE-770

Explicit planning of security-related actions requires defining limits, windows, and resource allocations, making allocation without throttling far less likely.

addresses: CWE-770

Measures of performance include tracking allocation behavior and throttling effectiveness, reducing the window for resource exhaustion attacks.

addresses: CWE-770

Imposes an inactivity-based limit on network resource allocation, throttling the number of concurrently held connections.
