18.11.3
CVE-2025-14869 describes a denial-of-service vulnerability discovered in GitLab Community Edition (CE) and Enterprise Edition (EE). This flaw allows an unauthenticated user to trigger a DoS condition by exploiting specific API endpoints with specially crafted payloads. The vulnerability impacts versions 18.5.0 through 18.11.3 and is resolved in version 18.11.3.
Impacto e Cenários de Ataquetraduzindo…
Successful exploitation of CVE-2025-14869 can lead to a denial-of-service condition, rendering affected GitLab instances unavailable to legitimate users. An attacker could repeatedly send malicious payloads, overwhelming the server's resources and causing it to crash or become unresponsive. The impact extends beyond simple service disruption; prolonged DoS attacks can hinder critical development workflows, impact CI/CD pipelines, and potentially lead to data loss if recovery is delayed. While the vulnerability requires no authentication, the attacker needs to be able to reach the targeted API endpoints, which might be restricted by firewalls or network configurations.

Mitigação e Soluções Alternativastraduzindo…
The primary mitigation for CVE-2025-14869 is to upgrade GitLab to version 18.11.3 or later. If immediate upgrading is not feasible, consider implementing rate limiting on the affected API endpoints to restrict the number of requests from a single source within a given timeframe. Web Application Firewalls (WAFs) configured to detect and block malicious payloads targeting API endpoints can also provide a temporary layer of protection. Review GitLab's network configuration to ensure only authorized traffic can access the API endpoints.
