Vulnerability Title
Word Replacer <= 0.4 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'Replacement' Parameter
Source: NVD (National Vulnerability Database)
Vulnerability Description
The Word Replacer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'replacement' parameter in all versions up to, and including, 0.4. This is due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
