CVE-2023-2836 is a medium-severity vulnerability rated 4.8/10 on the CVSS scale. The CRM Perks Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via form settings in versions up to, and including, 1.1.1 due to insufficient input sanitization and output escaping.

EPSS estimates a 0.60% chance of exploitation in the next 30 days.
