AI-suggested

European organizations should immediately audit their Coolify deployments to identify affected versions (<=4.0.0-beta.434). Until a patch is available, restrict member-level user permissions to the minimum necessary and monitor invitation link usage closely. Implement network segmentation and access controls to limit exposure of Coolify management interfaces. Use multi-factor authentication (MFA) for all administrative accounts to add an additional layer of protection. Consider disabling or tightly controlling the invitation link feature if possible. Regularly review logs for suspicious activity related to invitation links and privilege escalations. Engage with the Coolify community or vendor for updates on patches or mitigations. Additionally, implement incident response plans to quickly revoke compromised credentials and restore secure configurations if exploitation is suspected.

Description

CVE-2025-64423 is a high-severity improper authentication vulnerability in Coolify versions up to 4.0.0-beta.434. It allows low-privileged users to intercept and use administrator invitation links before the intended recipient, resulting in privilege escalation to administrator level without requiring user interaction. The vulnerability does not require UI interaction but does require the attacker to have low-level membership access. Exploitation can lead to full administrative control over the Coolify instance, compromising confidentiality, integrity, and availability of managed servers and applications. No patch is currently confirmed available, and no known exploits are reported in the wild. European organizations using Coolify for server and application management should urgently assess exposure and implement mitigations to prevent unauthorized privilege escalation.
