Name of the Vulnerable Software and Affected Versions iWR Tooltip versions prior to 1.1

Description The plugin contains a Stored Cross-Site Scripting issue within the iwrtooltip shortcode. The iwr tooltip() function fails to properly sanitize input and escape output for user-supplied attributes. Specifically, the title attribute is concatenated directly into an HTML attribute without using esc attr() or other escaping methods. This allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages, which execute when a user visits the affected page.

Recommendations Update the plugin to a version later than 1.0. As a temporary mitigation, restrict the ability of users with contributor-level access to edit pages or use the iwrtooltip shortcode.
