CVE-2025-64422 | Rate-limit bypass on login via X-Forwarded-Host header

Exp

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.

4.3 3.1 MEDIUM
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:L)
Might cause slowdowns, glitches, or partial disruption—not a full brick.
