CVE-2025-64422 is a medium-severity Allocation of Resources Without Limits or Throttling (CWE-770) vulnerability in Coollabs Coolify. Its CVSS base score is 5.5 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Brute Force (T1110); ranked at the 17th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-7 (Unsuccessful Logon Attempts) — see the control section below for these in your framework.

Vulnerability Data
Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. In Coolify vstarting with version 4.0.0-beta.434, the /login endpoint advertises a rate limit of 5 requests but can be trivially bypassed by rotating the X-Forwarded-For header. This…

enables unlimited credential stuffing and brute-force attempts against user and admin accounts. As of time of publication, it is unclear if a patch is available.

Why these techniques?
The rate-limit bypass via X-Forwarded-For rotation directly enables unlimited credential stuffing (T1110.004) and brute-force (T1110) attacks against login credentials.

Mitigating Controls (NIST 800-53 r5) AI
Directly enforces limits on consecutive invalid logon attempts, blocking the brute-force and credential-stuffing attacks enabled by the bypassed rate limit on /login.
Requires the system to enforce the advertised authentication rate limit regardless of client-supplied headers such as X-Forwarded-For.
Boundary protection mechanisms can validate or ignore untrusted proxy headers and apply rate limiting at the network edge before requests reach the login endpoint.

Baseline comparison of CPU, memory and bandwidth usage helps surface uncontrolled resource allocations before they cause service degradation.
Capacity projections and elasticity measures ensure that allocation requests are bounded and can be throttled, reducing the window in which an attacker can force unbounded resource reservations.
Defining retention periods and deletion schedules for backup copies prevents indefinite accumulation of data on storage media without corresponding resource-management controls.
Architectural redundancy and automatic failover limit the impact of an attacker who forces excessive allocations, because spare capacity can absorb the load until the primary instance recovers.
Documented incident response procedures that include activation of continuity plans and controlled recovery help ensure that resource consumption triggered by an incident is bounded and managed rather than left unbounded.
Mandating tested continuity procedures that preserve or replace resource-limiting controls prevents an attacker from exploiting the absence of throttling mechanisms during an outage.
