Vulnerabilities
- Medium 4.8
CVE-2021-36849admin≤ 3.8.1
WordPress Social Media Share Buttons plugin <= 3.8.1 - Authenticated Stored Cross-Site Scripting (XSS) vulnerability
- Medium 4.3
CVE-2025-22319login required≤ 4.0.47
WordPress MashShare plugin <= 4.0.47 - Broken Access Control vulnerability
The access label is read from the record's own text (e.g. “subscriber+”: subscriber and above). When the text names no role, CVSS decides between “login required” and “high privilege”; no role name is invented. “Needs a click”: the attack depends on a logged-in user following a link (CSRF, reflected XSS).
