What it is

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.
