Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N

CVSS	6.4 (Medium)
Publicly Published	August 2, 2023
Last Updated	January 22, 2024

Description

The Simple Share Follow Button plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcode in versions up to, and including, 1.03 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
