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.","state":0,"publishedAt":"2026-06-26T16:46:17.28+00:00","modifiedAt":"2026-06-27T02:47:55.779+00:00","affected":[{"ecosystem":"Vendor product","name":"mise","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"jdx\",\n                    \"product\": \"mise\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2026.6.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N","score":6.3,"severity":"MEDIUM"}],"references":["https://github.com/jdx/mise/security/advisories/GHSA-29hf-rm4x-xxph"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-55448","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-55448","identifiers":["CVE-2026-55448"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
