Description

KanaDojo before 0.1.18 contains a sandbox escape vulnerability that allows an attacker to execute arbitrary code by exploiting the explicit passing of the global require function into a Node.js vm.runInNewContext() sandbox context in the issue-auto-respond.yml workflow. Attackers can submit a pull request modifying messages.cjs to import arbitrary Node.js modules, bypassing sandbox restrictions and achieving remote code execution with full GitHub Actions runner privileges including access to AUTOMATION_PR_TOKEN.
