HIGH

Soft Serve Affected by an Authentication Bypass

Published January 21, 2026Updated February 3, 2026Source: osv

Summary

### Impact _What kind of vulnerability is it? Who is impacted?_ This issue impacts every Soft Serve instance. A critical authentication bypass 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. ### Patches _Has the problem been patched? What versions should users upgrade to?_ Yes, please upgrade to version 0.11.3 as soon as possible. ### Workarounds _Is there a way for users to fix or remediate the vulnerability without upgrading?_ You need to upgrade
