CVE-2021-24918

Versions of the Custom Facebook Feed (Smash Balloon Social Post Feed) plugin below 4.0.1 saved their configuration without checking user capabilities or verifying a nonce. Because of that missing authorization check, any authenticated user — regardless of role — could change the plugin's settings and inject arbitrary JavaScript that would then run on every post and page of the site (stored cross-site scripting).
