CVE-2024-5226 is a stored cross-site scripting vulnerability in the Fuse Social Floating Sidebar WordPress plugin due to improper input neutralization of SVG files uploaded through the plugin's file upload functionality. This allows authenticated users with contributor or higher privileges to inject arbitrary web scripts that execute in the context of other users viewing the injected pages. The vulnerability affects all versions up to and including 5.4.10. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and impacts on confidentiality and integrity with no availability impact.

Successful exploitation allows an authenticated contributor or higher to inject malicious scripts that execute in other users' browsers when they access the compromised pages. This can lead to unauthorized actions performed on behalf of users, data disclosure, or session hijacking. There is no indication of known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access to trusted users only and consider disabling or limiting SVG file uploads in the plugin. Monitor for updates from the vendor and apply any official patches promptly once released.
