What the vulnerability does

01Description

MISP modules are autonomous modules that can be used to extend MISP for new services. In 3.0.7 and earlier, a Cross-Site Request Forgery vulnerability in the MISP Modules website allowed an attacker to cause an authenticated user to submit unintended requests to the home endpoint. The vulnerability was due to the home blueprint being exempted from CSRF protection. This could allow modification of session query data in the context of the authenticated user. The issue was fixed by enabling CSRF protection for the affected blueprint and hardening query parsing.
