Name of the Vulnerable Software and Affected Versions The Modal Window plugin for WordPress versions up to, and including, 5.3.8

Description The issue arises from insufficient input sanitization and output escaping on user-supplied attributes in the plugin's shortcode(s), allowing authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages. This enables the execution of injected scripts whenever a user accesses an injected page.

Recommendations For versions up to, and including, 5.3.8, update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting the use of the plugin's shortcode(s) to minimize the risk of exploitation.
