CVE-2023-3170 is a medium-severity vulnerability rated 4.8/10 on the CVSS scale. The tagDiv Composer WordPress plugin before 4.2, used as a companion by the Newspaper and Newsmag themes from tagDiv, does not validate and escape some settings, which could allow users with Admin privileges to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup). EPSS estimates a 0.38% chance of exploitation in the next 30 days.
