CVE-2026-59172

7.8 HIGH 0.2% exploit odds Fix listed Code execution Library

What it is

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.
