Details
Summary
CVE-2023-4995 is a Stored Cross-Site Scripting (XSS) vulnerability affecting the Embed Calendly plugin for WordPress. This issue, impacting versions up to and including 3.6, arises due to insufficient input sanitization and output escaping on user-supplied attributes when using the 'calendly' shortcode. As a result, authenticated attackers with contributor-level permissions and above can inject arbitrary web scripts, causing these scripts to execute whenever an end-user accesses an affected page. This vulnerability poses a significant risk, as it can lead to data theft, unauthorized access, and other malicious activities. It is crucial for WordPress users running the Embed Calendly plugin to update to the latest version immediately to mitigate this threat.
