Name of the Vulnerable Software and Affected Versions Instant-Quote.co Quotation Page plugin for WordPress versions prior to 1.3.5

Description Stored Cross-Site Scripting (XSS) occurs due to insufficient input sanitization and output escaping within shortcode attributes. Authenticated attackers with contributor-level access or higher can inject arbitrary web scripts into pages. These scripts execute when a user accesses the affected page. For example, a contributor can embed a malicious shortcode in a post submitted for review, triggering script execution when an administrator previews or views the post.

Recommendations Update the plugin to a version newer than 1.3.4.
