MediumCVSS 6.8Exploitation Probability (EPSS)
Low risk14th percentile - higher than 14% of all known CVEs
Summary
The Joli Table Of Contents WordPress plugin before version 3.0.3 does not sanitise or escape a shortcode attribute value before outputting it inside an HTML element's attribute, allowing users with the Author role and above to inject arbitrary HTML attributes and JavaScript that execute in the browser of any user who views the post, including higher-privileged users such as administrators. This crosses a privilege boundary even on multisite, where such users are not permitted to post unfiltered HTML.
Risk Assessment
Risk includes session hijacking of administrators, data theft, defacement, and malware distribution to visitors.
Recommendation
Update the plugin to version 3.0.3 or later. Restrict roles that can publish content and apply the principle of least privilege.
