{"id":"CVE-2026-55448","aliases":["GHSA-29hf-rm4x-xxph"],"url":"https://o3.security/vulnerability/CVE-2026-55448","summary":"mise: Local credential_command executes untrusted config","details":"mise manages dev tools like node, python, cmake, and terraform. From 2026.3.15 until 2026.6.4, mise loads github.credential_command from local project config before any trust decision, then executes that value with sh -c when resolving a GitHub token. An attacker who can place a .mise.toml in a repository can execute arbitrary shell commands when the victim runs a GitHub-related mise command and no higher-priority GitHub token environment variable is set. This vulnerability is fixed in 2026.6.4.","published":"2026-06-26T16:46:17.280Z","modified":"2026-08-12T03:51:32.856882224Z","cvss":{"score":6.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N"},"epss":{"score":0.00158,"percentile":0.05291,"asOf":"2026-09-12"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"mise","fixedVersion":"2026.6.4"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55448.json"},{"type":"ADVISORY","url":"https://github.com/jdx/mise/security/advisories/GHSA-29hf-rm4x-xxph"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55448"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:32.856882224Z"}}
