CVE-2023-4646

Name of the Vulnerable Software and Affected Versions The Simple Posts Ticker WordPress plugin versions prior to 1.1.6

Description The issue concerns the lack of validation and escaping of certain shortcode attributes in the plugin, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks. This occurs when these attributes are outputted back in a page or post where the shortcode is embedded.

Recommendations For versions prior to 1.1.6, update to version 1.1.6 or later to resolve the issue. As a temporary workaround, consider restricting the use of the vulnerable shortcode attributes until a patch is applied.
