CVE-2026-48546
KanaDojo < 0.1.18 Sandbox Escape RCE via messages.cjs
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.

Action Type Old Value New Value Added Translation Title: kana-dojo de lingdojo, Description: KanaDojo antes de 0.1.18 contiene una vulnerabilidad de escape de sandbox que permite a un atacante ejecutar código arbitrario explotando el paso explícito de la función global require a un contexto de sandbox de Node.js vm.runInNewContext() en el flujo de trabajo issue-auto-respond.yml. Los atacantes pueden enviar una solicitud de extracción modificando messages.cjs para importar módulos arbitrarios de Node.js, eludiendo las restricciones de la sandbox y logrando la ejecución remota de código con privilegios completos de ejecutor de GitHub Actions, incluyendo acceso a AUTOMATION_PR_TOKEN. -
