CVE-2026-26307 Gitea CVE debrief

Who should care

Administrators and users of Gitea versions before 1.25.5 should apply the patch to prevent potential resource exhaustion attacks. This includes operators managing Gitea instances, platform administrators, vulnerability management teams, and security teams responsible for monitoring and defending against such attacks.

Technical summary

Gitea versions before 1.25.5 do not enforce a timeout on git grep searches, allowing expensive searches to consume server resources. This vulnerability has a CVSS score of 7.5 and is classified as HIGH severity. Affected deployments should apply the patch to prevent potential resource exhaustion attacks. The vulnerability is caused by the lack of a timeout mechanism in git grep searches, which can be exploited by attackers to perform expensive searches and consume server resources. This can lead to denial-of-service attacks and impact the availability of Gitea instances. Administrators and users of Gitea versions before 1.25.5 should apply the patch to prevent potential resource exhaustion attacks.

Defensive priority

Apply the patch to Gitea versions before 1.25.5 to prevent potential resource exhaustion attacks. Restrict access to git grep searches and monitor server resources for unusual activity.

Recommended defensive actions

• Apply the patch to Gitea versions before 1.25.5
• Restrict access to git grep searches
