CVE-2026-7250: 
GitLab Analyse et atténuation des vulnérabilités

CVE-2026-7250 is a denial-of-service vulnerability in GitLab CE/EE caused by improper input validation in the API request parsing middleware. It affects all versions from 12.10 before 18.10.8, 18.11 before 18.11.5, and 19.0 before 19.0.2. The vulnerability was disclosed on June 11, 2026, and has a CVSS v3.1 base score of 7.5 (High) (GitHub Advisory, GitLab Patch Release).

The root cause is classified as CWE-770 (Allocation of Resources Without Limits or Throttling), meaning the API request parsing middleware fails to impose adequate restrictions on resource allocation when processing certain malformed or oversized inputs. An unauthenticated remote attacker can craft malicious API requests that trigger excessive resource consumption in the middleware layer, causing the GitLab service to become unavailable. No authentication, user interaction, or special privileges are required to exploit this vulnerability, and it is exploitable over the network with low attack complexity (GitHub Advisory).

Successful exploitation results in a denial-of-service condition, rendering the GitLab instance unavailable to legitimate users. The impact is limited to availability — there is no confidentiality or integrity impact, meaning attackers cannot access or modify data through this vulnerability alone. However, disruption of a GitLab instance could halt CI/CD pipelines, block code commits, and impair development workflows for all users of the affected instance (GitHub Advisory).

GitLab has released patched versions addressing this vulnerability: 18.10.8, 18.11.5, and 19.0.2. Administrators should upgrade to the appropriate fixed version based on their current deployment. No configuration-based workaround has been published; upgrading is the recommended and only confirmed remediation (GitLab Patch Release, GitHub Advisory).

Security news outlets including GBHackers and CyberPress covered the patch release as part of GitLab's broader June 2026 security update, noting multiple vulnerabilities addressed simultaneously (GBHackers, CyberPress). SecurityOnline.info also reported on the GitLab 19.0.2 security updates shortly after disclosure. Coverage generally characterized the vulnerability as high severity due to its unauthenticated network exploitability, though no significant researcher commentary or threat actor attribution has emerged.
