Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVE CVE-2024-2857
CVSS High (7.2)
Publicly Published March 25, 2024

Researcher Bob Matyas
Description

The Simple Buttons Creator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the "Add Button" functionality in all versions up to, and including, 1.04 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. NOTE: This issue is exploitable as an unauthenticated user, as well as via Cross-Site Request Forgery, due to a lack of authorization and nonce checks, respectively, within the affected function.
