Post summary
The post announces critical Gitea vulnerabilities (CVE‑2026‑20896 and CVE‑2026‑22874) that allow account takeover and SSRF, and notes that patches are available.
🚨 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+

🚨Critical - Gitea: Three CI/CD & SSRF Flaws Fixed in 1.26.x (CVE-2026-58426, CVE-2026-22874, CVE-2026-58424)
Gitea patched three issues, mostly in its Actions CI/CD. CVE-2026-58426 (9.6): an HMAC ambiguity in Actions Artifacts V4 signed URLs allows cross-repository artifact reads and cross-task upload-state writes. CVE-2026-22874 (9.6): incomplete SSRF protection in webhook and migration allow-list filtering lets an authenticated user reach internal services and metadata endpoints.
CVE-2026-58424 (8.9): a permanent fork-PR workflow approval-gate bypass lets a fork PR author run CI workflows without the required maintainer approval, exposing runner secrets and resources. All three need only a low-privileged authenticated account, and their fixes are staggered across 1.26.2–1.26.4.
👉Upgrade Gitea to 1.26.4 (covers all three).
Post summary
Gitea has patched three critical vulnerabilities—an HMAC ambiguity in CI/CD artifact URLs, an SSRF flaw in webhooks, and a fork‑PR bypass—by release 1.26.4, and users are urged to upgrade promptly.
