Title source: cnaExploitation Summary
EIP tracks 1 public exploit for CVE-2026-59734. PoCs published by cybertechajju.
AI-analyzed exploit summary This repository contains a functional proof-of-concept exploit for CVE-2026-59734, an OS command injection vulnerability in Coolify's health check configuration. The exploit demonstrates how unauthenticated parameters (health_check_host, health_check_method, health_check_path) are interpolated into shell commands without sanitization, allowing arbitrary command execution in deployment containers.
Description
Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.469, Coolify's app/Jobs/ApplicationDeploymentJob.php generate_healthcheck_commands() function directly interpolated the health_check_host, health_check_method, and health_check_path parameters into shell commands without proper sanitization, allowing authenticated users to execute arbitrary commands inside deployment containers. This issue is fixed in version 4.0.0-beta.469.
