{"cve":"CVE-2026-59172","nvd":{"published":"2026-10-28T14:17:04.447","modified":"2026-10-28T14:17:04.447","status":"Received","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-829"],"references":["https://github.com/candid82/joker/commit/f207521ef8abc22f30740591c3de5062c1aa628c","https://github.com/candid82/joker/security/advisories/GHSA-m835-3cm9-rggg","https://github.com/candid82/joker/tree/v1.8.2"],"products":[],"source":"nvd","synced_at":"2026-10-28T14:33:46.215572803+00:00"},"epss":null,"kev":null,"osv":[{"id":"GHSA-m835-3cm9-rggg","url":"https://osv.dev/vulnerability/GHSA-m835-3cm9-rggg","summary":"Joker linter executed project-local .jokerd/linter.* files during linting","modified":"2026-09-17T17:41:02.160584664Z","packages":[{"ecosystem":"Go","name":"github.com/candid82/joker","purl":"pkg:golang/github.com/candid82/joker","ranges":["<1.8.2"],"fixed":["1.8.2"]}]},{"id":"GO-2026-6450","url":"https://osv.dev/vulnerability/GO-2026-6450","summary":"Joker linter executed project-local .jokerd/linter.* files during linting in github.com/candid82/joker","modified":"2026-09-17T17:30:12.886884713Z","packages":[{"ecosystem":"Go","name":"github.com/candid82/joker","purl":"pkg:golang/github.com/candid82/joker","ranges":["<1.8.2"],"fixed":["1.8.2"]}]}],"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).
