Deeper analysis
The Contact Form 7 plugin for WordPress is vulnerable to reflected cross-site scripting via the active-tab parameter in all versions up to and including 5.9. The issue stems from insufficient input sanitization and output escaping, as classified under CWE-79, and carries a CVSS 3.1 score of 6.1 reflecting network attack vector, low complexity, no required privileges, and required user interaction with changed scope.
Unauthenticated attackers can exploit the flaw by crafting malicious links that inject arbitrary web scripts; successful execution occurs if a targeted user clicks the link, enabling limited impacts to confidentiality and integrity within the affected site's context.
Advisories reference a plugin changeset that addresses the parameter handling in edit-contact-form.php, indicating that updating to a patched version of Contact Form 7 mitigates the exposure, with additional details available through Wordfence threat intelligence reporting.
The EPSS score stands at 0.6848 with an identical peak value and no documented real-world exploitation activity.
