3DescriptionGitHub Advisory
Soft Serve is a self-hostable Git server for the command line. Versions 0.11.2 and below have a critical authentication bypass vulnerability that allows an attacker to impersonate any user (including admin) by "offering" the victim's public key during the SSH handshake before authenticating with their own valid key. This occurs because the user identity is stored in the session context during the "offer" phase and is not cleared if that specific authentication attempt fails. This issue has been fixed in version 0.11.3.
AnalysisAI
Soft Serve self-hosted Git server versions 0.11.2 and below have a critical authentication bypass that allows unauthenticated access to private repositories.
Technical ContextAI
Soft Serve <= 0.11.2 has a CWE-289 authentication bypass using an alternate path that allows unauthenticated users to access private Git repositories, including cloning, reading code, and potentially pushing changes.
RemediationAI
Update to a patched version immediately. Audit Git access logs for unauthorized repository access.
