High CVSS 7.1
CVE-2026-20779
Gitea versions from 1.5.0 before 1.26.3 have a TOTP single-use enforcement defect that allows a valid TOTP code to be accepted more than once across web two-factor authentication flows and the Basic Auth X-Gitea-OTP path.
What this means
- Exposure
- Exploitable remotely over the network and without authentication — but only if a user opens booby-trapped content.
- Impact
- An attacker can read sensitive data and alter some data.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
