{"id":"CVE-2026-59172","state":"PUBLISHED","title":"Joker linter executed project-local .jokerd/linter.* files during linting","description":"Joker is a small Clojure interpreter, linter and formatter written in Go. Prior to 1.8.2, `joker --lint <file>` walks upward from the linted file to locate a `.jokerd/` directory and executes matching `linter.*` files before linting. Those files contain executable Joker/Clojure code, so linting a file inside an untrusted repository can execute repository-supplied code with the linter user's privileges. Editor integrations and CI jobs that automatically lint checked-out source can trigger this behavior. The patch stops executing project-local linter customizations and loads executable customization only from the user's home directory. This issue is fixed in version 1.8.2.","publishedAt":"2026-10-28T13:07:35.230Z","updatedAt":"2026-10-28T16:07:17.268Z","severity":{"score":7.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["candid82 joker"],"affected":[{"vendor":"candid82","product":"joker","versions":[{"version":"< 1.8.2","status":"affected"}]}],"references":["https://github.com/candid82/joker/security/advisories/GHSA-m835-3cm9-rggg","https://github.com/candid82/joker/commit/f207521ef8abc22f30740591c3de5062c1aa628c","https://github.com/candid82/joker/tree/v1.8.2"],"weaknesses":["CWE-829"],"ingestedAt":"2026-10-29T20:12:32.778Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/59xxx/CVE-2026-59172.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-59172","state":"PUBLISHED","datePublished":"2026-10-28T13:07:35.230Z","dateUpdated":"2026-10-28T16:07:17.268Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-07-02T16:50:27.888Z"},"containers":{"cna":{"title":"Joker linter executed project-local .jokerd/linter.* files during linting","descriptions":[{"lang":"en","value":"Joker is a small Clojure interpreter, linter and formatter written in Go.
