Vulnerability Title
Blog Floating Button <= 1.4.20 - Unauthenticated Stored XSS via User-Agent Header
Source: CVE Program / CVE List V5
Vulnerability Description
The Blog Floating Button WordPress plugin through 1.4.20 does not sanitize or escape the visitor User-Agent header, which it stores through an unauthenticated tracking REST endpoint and later renders unescaped in an administrator report page. This allows an unauthenticated attacker to store a malicious script that executes in the session of any administrator who views the access report, leading to site takeover.
