# CVE-2026-22874: Gitea: Incomplete SSRF Protection in Webhook and Migration Allow-list Default Filter

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 0.5% , percentile 39: FIRST’s model estimates a 0.5% chance of exploitation activity in the next 30 days, higher than 39% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes code.gitea.io/gitea (Go) < 1.26.3, fixed in 1.26.3 . Check your lockfile, including transitive dependencies.

## What it is

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

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
