Accessibility <= 1.0.2 - Authenticated (Administrator+) Stored Cross-Site Scritping

5.5
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSS 5.5 (Medium)
Publicly Published November 2, 2022
Last Updated January 22, 2024

Description

The Accessibility plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'attachments_alt' and 'attachments_title' parameters in versions up to, and including, 1.0.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with administrative privileges 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.
