WordPress Plugin Vulnerabilities

Link Whisper Free < 0.9.1 - Unauthenticated Stored Cross-Site Scripting

Description

The Link Whisper Free plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the user_id parameter in all versions up to, and including, 0.9.0 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.

Fixed in 0.9.1
