CVE-2026-22874: Gitea webhook and migration allow-list filtering permits SSRF

Noroxi assessment

Priority: Monitor (action score 38/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.46% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: code.gitea.io/gitea (Go) 1.26.3.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to code.gitea.io/gitea (Go) 1.26.3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Gitea versions up to and including 1.26.2 have incomplete SSRF protection in webhook and migration allow-list filtering.
