CVE-2026-0753
Published: 14 February 2026
Summary
CVE-2026-0753 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 18.2th 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-2026-0753 is a reflected cross-site scripting (XSS) vulnerability in the Super Simple Contact Form plugin for WordPress, affecting all versions up to and including 1.6.2. The issue stems from insufficient input sanitization and output escaping of the 'sscf_name' parameter, classified under CWE-79. Published on 2026-02-14, it carries a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N), indicating high severity due to its network accessibility, low complexity, lack of required privileges, changed scope, and potential for limited confidentiality and integrity impacts.
Unauthenticated attackers can exploit this vulnerability over the network by crafting malicious payloads in the 'sscf_name' parameter. Exploitation requires tricking a user, such as site administrators or visitors, into performing an action like clicking a specially crafted link, which reflects and executes arbitrary web scripts in the victim's browser context on affected pages.
Advisories and references, including Wordfence threat intelligence and the plugin's WordPress.org page, provide details on the vulnerability. Code inspection via WordPress plugin trac repositories highlights the issue at line 152 in super-simple-contact-form.php for both the 1.6.2 tag and trunk versions, with the vulnerable 1.6.2 download available for analysis. Security practitioners should review these for patch information and update to versions beyond 1.6.2.

Why these techniques?
Reflected XSS in public-facing WordPress plugin directly enables exploitation of a network-accessible web application (T1190) via crafted parameter input requiring user interaction to trigger script execution.

Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation and sanitization of untrusted input such as the 'sscf_name' parameter before processing, eliminating the root cause of the reflected XSS.
Mandates output filtering/escaping of data derived from user input before rendering in responses, preventing script execution in the victim's browser.
Requires mechanisms to detect and block malicious code (scripts) delivered via network inputs, providing a secondary layer against exploitation of the unsanitized parameter.
