GHSA-362W-HWF4-9HCX

Vulnerability from github – Published: 2024-02-29 03:33 – Updated: 2026-04-08 18:32

Details

The Simple Share Buttons Adder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 8.4.11 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Severity

4.4 (Medium)
