🚨 Three Gitea/Gogs vulnerabilities just dropped — and one is a CVSS 9.8 authentication bypass.
If you self-host Gitea or Gogs, this is not a “patch later” situation:
⚠️ CVE-2026-20896 — Gitea Docker auth bypass
Anyone can impersonate any user with one HTTP header: `X-WEBAUTH-USER: admin`
⚠️ CVE-2026-52807 — Stored DOM XSS
A malicious milestone name can survive escaping and execute through Semantic UI.
⚠️ CVE-2026-22874 — Webhook SSRF
Gitea webhooks can become a path to AWS IMDS, cloud credentials, S3, Secrets Manager, ECR, and full cloud privilege abuse.
Self-hosted Git platforms hold source code, CI/CD secrets, deploy keys, webhooks, tokens, and internal infrastructure access.
Your code. Your secrets. Their access.
Upgrade now:
Gitea 1.26.3+
Gogs 0.14.3+
