The Correct Prices plugin for WordPress is vulnerable to Reflected Cross-Site Scripting. The CVSS score is 6.1, indicating a medium severity vulnerability.

Defensive priority

Medium priority due to the CVSS score of 6.1 and the potential for unauthenticated attackers to inject arbitrary web scripts.

Recommended defensive actions

  • Update the Correct Prices plugin to a version beyond 1.0, if available.
  • Implement input sanitization and output escaping for the correct_prices_page() function.
  • Use a web application firewall (WAF) to detect and prevent cross-site scripting attacks.
  • Regularly monitor and update WordPress plugins to ensure the latest security patches are applied.
  • 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.
