CVE-2023-4995

Name of the Vulnerable Software and Affected Versions Embed Calendly plugin for WordPress versions up to, and including, 3.6

Description The issue is related to Stored Cross-Site Scripting via the 'calendly' shortcode due to insufficient input sanitization and output escaping on user-supplied attributes. This allows authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For Embed Calendly plugin for WordPress versions up to, and including, 3.6, update to a version higher than 3.6 to resolve the issue. As a temporary workaround, consider restricting access to the 'calendly' shortcode for users with contributor-level and above permissions until a patch is available.
