What is CVE-2025-64422?

An authentication bypass vulnerability has been identified in Coolify, an open-source tool for managing servers, applications, and databases. Starting from version 4.0.0-beta.434, the /login endpoint claims to enforce a rate limit of 5 requests. However, this limit can be easily circumvented by modifying the X-Forwarded-For header, allowing attackers to perform unlimited credential stuffing and brute-force attempts against both user and admin accounts. Currently, it is not confirmed whether a patch has been released to address this issue.
