Vulnerability Overview

The OOPSpam Anti-Spam plugin for WordPress is vulnerable to Stored Cross-Site Scripting via options such as 'oopspam_wpregister_spam_message', 'oopspam_woo_spam_message', and 'oopspam_give_spam_message' (as well as numerous others) in versions up to, and including, 1.1.35 due to insufficient input sanitization and output escaping. This makes it possible for administrator-level attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Technical Analysis

REMEDIATION: Update to version 1.1.36, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
