AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N

Name of the Vulnerable Software and Affected Versions: The Simple Popup Plugin versions up to, and including, 4.5

Description: The issue arises from insufficient input sanitization and output escaping on user-supplied attributes in the plugin's [popup] shortcode, allowing authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages. These scripts will execute whenever a user accesses an injected page.

Recommendations: For versions up to, and including, 4.5, update to a version that addresses the insufficient input sanitization and output escaping issue in the [popup] shortcode. As a temporary workaround, consider restricting access to the [popup] shortcode for users with contributor-level access and above until a patch is available.
