Published: 03 March 2026
Summary
CVE-2026-2568 is a high-severity Cross-site Scripting (CWE-79) vulnerability in Wordpress (inferred from references). Its CVSS base score is 7.2 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 35.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-15 (Information Output Filtering).
Deeper analysis
CVE-2026-2568 is a stored cross-site scripting (XSS) vulnerability, classified under CWE-79, in the WP Zendesk for Contact Form 7, WPForms, Elementor, Formidable and Ninja Forms plugin for WordPress. It affects all versions up to and including 1.1.5. The issue arises from insufficient input sanitization and output escaping of form submission data, enabling the injection of arbitrary web scripts into pages.
Unauthenticated attackers can exploit this vulnerability over the network with low complexity, no privileges, and no user interaction required, as indicated by its CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N). By submitting malicious scripts via supported forms, attackers can store them on the site; these scripts then execute in the browsers of any users who access the affected pages, potentially enabling theft of sensitive data, session hijacking, or site defacement.
Mitigation details are available in the WordPress plugin trac changeset at https://plugins.trac.wordpress.org/changeset/3467904/, which addresses the vulnerability. Further analysis appears in the Wordfence threat intelligence advisory at https://www.wordfence.com/threat-intel/vulnerabilities/id/27d26d1c-d027-4a22-af49-4d7684d36d40?source=cve. Security practitioners should ensure sites update the plugin to a version beyond 1.1.5.

Why these techniques?
Stored XSS in public-facing WordPress forms directly enables T1190 (exploiting the unauthenticated form endpoint). Payload execution in victim browsers facilitates T1056.001 (keylogging/input theft), T1539 (cookie theft), T1185 (session hijacking), and T1491.001 (page defacement).

Directly requires validation of form submission data to block unsanitized scripts before storage.
Requires output filtering/escaping of stored form data so injected scripts cannot execute in user browsers.
Mandates timely remediation (plugin update beyond 1.1.5) to eliminate the input/output flaw.
