Affected Systems
LambertGroup HTML5 Radio Player – WPBakery Page Builder Addon version 2.5 or earlier, used as an addon in WordPress sites
Risk and Exploitability
The CVSS score is 7.1, indicating moderate to high severity. EPSS is below 1 %, implying a low probability of exploitation at this time. The vulnerability is not listed in the CISA KEV catalog.
