Message Filter for Contact Form 7 <= 1.6.3 - Missing Authorization to Authenticated (Subscriber+) New Filter Creation

The Message Filter for Contact Form 7 plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the saveFilter() function in all versions up to, and including, 1.6.3. This makes it possible for authenticated attackers, with Subscriber-level access and above, to create new filters. CVE-2024-54254 may be a duplicate of this CVE.
