CVE-2025-59934

Formbricks (pre-4.0.1) is affected by missing JWT signature verification. A token validation path uses jwt.decode without signature checks, allowing an attacker who knows a user’s user.id to craft a JWT with alg: none and authenticate or reset the victim’s password. The same validator is used for...
