CVE-2025-14157: GitLab can be overloaded by crafted API calls
CVE-2025-14157 · published 10 months ago
Summary
Any GitLab version before the recent patches can be tricked by a signed‑in user into using unlimited server resources, which may make the service slow or stop responding. This happens when the user sends specially crafted API requests with very large data. Update GitLab to the latest release or apply the provided security patch to prevent this.
