Detailsinfo

A vulnerability, which was classified as problematic, was found in Gogs up to 0.14.2. Affected is some unknown processing. The manipulation with an unknown input leads to a key expiration date vulnerability. CWE is classifying the issue as CWE-324. The product uses a cryptographic key or password past its expiration date, which diminishes its safety significantly by increasing the timing window for cracking attacks against that key. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-52809 since 06/08/2026. The exploitability is told to be difficult. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Successful exploitation requires user interaction by the victim. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1600.001 by the MITRE ATT&CK project.

Upgrading to version 0.14.3 eliminates this vulnerability. The upgrade is hosted for download at github.com.
