Name of the Vulnerable Software and Affected Versions The Simple Like Page Plugin for WordPress versions up to, and including, 1.5.1

Description The issue arises from insufficient input sanitization and output escaping on user-supplied attributes in the 'sfp-page-plugin' shortcode, allowing authenticated attackers with contributor-level and above permissions 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, 1.5.1, update to a version that addresses the insufficient input sanitization and output escaping issue in the 'sfp-page-plugin' shortcode. As a temporary workaround, consider restricting access to the 'sfp-page-plugin' shortcode for users with contributor-level and above permissions until a patch is available.
