CVE-2025-64425 Coollabs CVE debrief

Who should care

Defenders responsible for Coolify deployments, especially those using versions up to and including v4.0.0-beta.434, should assess exposure and prioritize verification and mitigation efforts.

Why it matters

Defenders should care about CVE-2025-64425 because it allows attackers to potentially take over accounts through manipulated password reset links in Coolify deployments. Roles responsible for Coolify deployments, especially those using vulnerable versions, should assess exposure and prioritize verification and mitigation efforts.

• Potential account takeover through password reset manipulation
• Exposure of sensitive authentication information
• Need for verification of affected versions and deployments
• Priority for patching or applying compensating controls

Technical summary

The vulnerability allows an attacker to initiate a password reset for a victim and modify the host header of the request to a malicious value, potentially leading to account takeover. This issue affects Coolify versions up to and including v4.0.0-beta.434. An attacker can exploit this by sending a password reset request with a modified host header, causing the victim to receive a password reset email with a link to the malicious host. If the victim clicks this link, their reset token is sent to the attacker's server, allowing the attacker to use it to change the victim's password and take over their account.

Defensive priority

Defenders should prioritize verifying exposure in their Coolify deployments, especially those using versions up to and including v4.0.0-beta.434, and assess the feasibility of compensating controls until an official patch is available.

Recommended defensive actions

• Verify exposure in Coolify deployments, especially those using versions up to and including v4.0.0-beta.434
• Assess the feasibility of compensating controls until an official patch is available
• Monitor for suspicious password reset activity
• Consider implementing additional security measures for authentication and account management
• Review relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
