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.","cvss_v4":{"vector":"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","score":8.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-289"],"references":["https://github.com/charmbracelet/soft-serve/commit/8539f9ad39918b67d612a35785a2b4326efc8741","https://github.com/charmbracelet/soft-serve/releases/tag/v0.11.3","https://github.com/charmbracelet/soft-serve/security/advisories/GHSA-pchf-49fh-w34r"],"products":["charm:soft_serve"],"source":"nvd","synced_at":"2026-10-19T22:21:16.563232421+00:00"},"epss":{"cve":"CVE-2026-24058","score":0.00578,"percentile":0.47627,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-pchf-49fh-w34r","url":"https://osv.dev/vulnerability/GHSA-pchf-49fh-w34r","summary":"Soft Serve Affected by an Authentication Bypass","modified":"2026-02-03T03:08:53.029033Z","packages":[{"ecosystem":"Go","name":"github.com/charmbracelet/soft-serve","purl":"pkg:golang/github.com/charmbracelet/soft-serve","ranges":["<0.11.3"],"fixed":["0.11.3"]}]},{"id":"GO-2026-4353","url":"https://osv.dev/vulnerability/GO-2026-4353","summary":"Soft Serve Affected by an Authentication Bypass in github.com/charmbracelet/soft-serve","modified":"2026-03-03T04:57:56.403257Z","packages":[{"ecosystem":"Go","name":"github.com/charmbracelet/soft-serve","purl":"pkg:golang/github.com/charmbracelet/soft-serve","ranges":["<0.11.3"],"fixed":["0.11.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
