Authorization Bypass Vulnerability in FlyingPress WordPress Plugin Allows Unauthorized CDN Configuration

CVE-2022-4948 · MEDIUM Severity

CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N

The FlyingPress plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on its AJAX actions in versions up to, and including, 3.9.6. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to interact with the plugin in ways administrators are intended to. One action (save_config) allows for the configuration of an external CDN. This could be used to include malicious javascript from a source controlled by the attacker.
