Who should care

Users of the Eventin – Event Calendar, Event Registration, Tickets & Booking (AI Powered) plugin for WordPress, particularly those with contributor-level access and above, should be aware of this vulnerability and take immediate action to protect their sites. Additionally, security teams and vulnerability management teams should review the affected scope and severity to determine the necessary course of action.

Technical summary

The Eventin plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) due to insufficient input sanitization and output escaping in the 'etn_faq_content' parameter. This allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts, which will execute when a user accesses an injected page. The vulnerability has a CVSS score of 6.4 and is considered Medium severity.

Defensive priority

Medium priority due to the CVSS score of 6.4 and the potential for authenticated attackers to inject malicious scripts.

Recommended defensive actions

  • Update the Eventin plugin to a version beyond 4.1.15
  • Implement additional input validation and output encoding for user-supplied content
  • Monitor for suspicious activity and injected scripts
  • Consider implementing a Web Application Firewall (WAF) to detect and prevent XSS attacks
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
