Kaya QR Code Generator <= 1.5.2 - Authenticated(Contributor+) Stored Cross-Site Scripting via url parameter
Strategic Overview
<= 1.5.2N/AVulnerability Overview
The Kaya QR Code Generator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'url' parameter passed to the 'wpkqcg_doDisplayQRCode' function via multiple methods including shortcodes in versions up to, and including, 1.5.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with contributor-level permissions or above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
