CVE-2026-52809

Gogs: Password-reset tokens use account-activation lifetime, ignoring RESET_PASSWORD_CODE_LIVES

Published Jun 24, 2026 CVSS 3.1 · 6.8 Medium EPSS < 1% KEV · Not listed
Description
Gogs is an open source self-hosted Git service. Prior to 0.14.3, password-reset tokens are generated using conf.Auth.ActivateCodeLives (the account-activation lifetime), not conf.Auth.ResetPasswordCodeLives. The token lifetime is baked into the token itself at generation time and is re-extracted from the token at verification time, making RESET_PASSWORD_CODE_LIVES irrelevant to actual enforcement. When an administrator configures a shorter reset window (e.g., 10 minutes) for compliance or security reasons, reset tokens remain exploitable for the full activation lifetime instead, while the reset email falsely advertises the shorter expiry. This vulnerability is fixed in 0.14.3.
