Headline
GHSA-m27m-h5gj-wwmg: Gogs allows argument Injection when tagging new releases
Impact
Unprivileged user accounts with at least one SSH key can read arbitrary files on the system. For instance, they could leak the configuration files that could contain database credentials ([database] *) and [security] SECRET_KEY. Attackers could also exfiltrate TLS certificates, other users’ repositories, and the Gogs database when the SQLite driver is enabled.
Patches
Unintended Git options has been ignored for creating tags (https://github.com/gogs/gogs/pull/7872). Users should upgrade to 0.13.1 or the latest 0.14.0+dev.
Workarounds
No viable workaround available, please only grant access to trusted users to your Gogs instance on affected versions.

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
