Who is impacted?_\n\nThis issue impacts every Soft Serve instance.\n\nA 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.\n\n### Patches\n_Has the problem been patched? What versions should users upgrade to?_\n\nYes, please upgrade to version 0.11.3 as soon as possible.\n\n### Workarounds\n_Is there a way for users to fix or remediate the vulnerability without upgrading?_\n\nYou need to upgrade","affected":[{"package":{"name":"github.com/charmbracelet/soft-serve","ecosystem":"Go","purl":"pkg:golang/github.com/charmbracelet/soft-serve"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.11.3"}]}],"database_specific":{"last_known_affected_version_range":"<= 0.11.2","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/01/GHSA-pchf-49fh-w34r/GHSA-pchf-49fh-w34r.json"}}],"references":[{"type":"WEB","url":"https://github.com/charmbracelet/soft-serve/security/advisories/GHSA-pchf-49fh-w34r"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-24058"},{"type":"WEB","url":"https://github.com/charmbracelet/soft-serve/commit/8539f9ad39918b67d612a35785a2b4326efc8741"},{"type":"PACKAGE","url":"https://github.com/charmbracelet/soft-serve"},{"type":"WEB","url":"https://github.com/charmbracelet/soft-serve/releases/tag/v0.11.3"}],"database_specific":{"cwe_ids":["CWE-289"],"github_reviewed":true,"github_reviewed_at":"2026-01-21T23:02:07Z","nvd_published_at":"2026-01-22T22:16:21Z","severity":"HIGH"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U"}]}
