CVE-2026-52809
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.
Summary dbcve.org
In Gogs prior to 0.14.3, password-reset tokens are generated using the account-activation lifetime (ActivateCodeLives) instead of the intended password-reset lifetime (ResetPasswordCodeLives). The token lifetime is embedded in the token at generation and extracted at verification, bypassing the ResetPasswordCodeLives configuration entirely, causing tokens to remain valid far longer than administrators expect.
Mitigation
Upgrade Gogs to version 0.14.3 or later to ensure password-reset tokens use the correct configuration value and respect the intended expiry window.
