CVE-2026-94379: MISP HTTP method validation bypass in login function

CVE-2026-94379 · Severity: info · Published 2026-09-21

MISP, an open-source threat intelligence platform, contains a flaw in its login function that allows attackers to bypass brute-force protection and multi-factor authentication by using non-standard HTTP methods. An unauthenticated attacker could exploit this to make unlimited login attempts without rate-limiting or two-factor authentication verification, potentially gaining unauthorized access to the system and its sensitive threat intelligence data.

Technologies: Misp. Vendors: Misp.

Technical details

The UsersController.php login() function uses an allowlist approach to validate HTTP methods, checking only for POST and PUT before enforcing brute-force blocklisting, OTP verification, and login-failure logging. An attacker can circumvent all three security controls by sending login requests with alternative HTTP methods (GET, DELETE, etc.), bypassing rate-limiting, 2FA, and audit trails. A patch adjusting the HTTP method validation has been published in commit ef4dc19.
