CVE-2026-41899 Details
Description
Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.474, POST /api/feedback has no authentication, no rate limiting, and no input validation, allowing arbitrary content to be forwarded directly to a Discord webhook and enabling spam, content injection, and webhook abuse. This issue is fixed in version 4.0.0-beta.474.
A vulnerability exists in Coolify versions prior to 4.0.0-beta.474, where the POST /api/feedback endpoint lacks authentication, rate limiting, and input validation. This oversight allows users to send arbitrary content directly to a Discord webhook, facilitating spam, content injection, and abuse of the webhook. The issue has been addressed in version 4.0.0-beta.474.
Users can update to Coolify version 4.0.0-beta.474 or later, where this vulnerability has been fixed. For those managing their own Coolify instances, it's recommended to add authentication and rate limiting to the feedback endpoint, as well as input validation in the controller.
