Critical Gitea vulnerability now exploited in the wild (CVE-2026-60004)

Attackers are actively exploiting critical Gitea RCE CVE-2026-60004 via the diffpatch endpoint, prompting CISA KEV addition and at least one cryptomining compromise.

CISA added CVE-2026-60004, a critical code injection flaw in Gitea's diffpatch endpoint, to its Known Exploited Vulnerabilities catalog after in-the-wild attacks. An attacker with repository write access, or an unauthenticated visitor on instances with open registration, can execute arbitrary shell commands as the Gitea OS user. A disclosed incident saw an automated scanner register an account and deploy a loader and cryptominer inside a Docker container within about 11 seconds, with no persistence mechanism found. Gitea patched the flaw in v1.27.1, and CISA ordered US federal civilian agencies to update by August 28, 2026.
