CVE-2026-0753: Super Simple Contact Form <= 1.6.2 - Reflected Cross-Site Scripting via 'sscf_name' Parameter

The Super Simple Contact Form plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'sscf_name' parameter in all versions up to, and including, 1.6.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

Security readout for executives and security teams

Plain-English summary

A WordPress contact form plugin can reflect unsafe input back into a page. An attacker could send a crafted link that runs script in the victim’s browser if clicked. This can support phishing, session-related abuse, or content manipulation within the affected site context.

Executive priority

Treat as a high-priority web risk for WordPress sites using this plugin. Prioritize public websites, administrator-facing workflows, and sites handling customer interactions. If the plugin is not installed, no action is needed beyond normal monitoring.

Technical view

CVE-2026-0753 is reflected XSS in Super Simple Contact Form through the sscf_name parameter in versions up to and including 1.6.2. Sources attribute it to insufficient input sanitization and output escaping. It is unauthenticated and network-reachable, but requires a user interaction such as following a malicious link.

Likely exposure

Exposure is limited to WordPress sites running Super Simple Contact Form at version 1.6.2 or earlier, especially where the form is publicly reachable. Sites not using this plugin are not affected based on the provided sources.

Exploitation context

The source bundle does not show CISA KEV listing or confirmed active exploitation. The practical risk is social engineering: attackers must get a target to open a crafted URL. Impact increases if the target is an authenticated site administrator.

Researcher notes

The provided record identifies CWE-79 and references WordPress Trac locations around line 152 for version 1.6.2 and trunk. The affected metadata is inconsistent, listing default unaffected while the description says all versions up to 1.6.2. No source in the bundle names a fixed version.

Mitigation direction

  • Inventory WordPress sites for Super Simple Contact Form installations.
  • Check the installed plugin version against 1.6.2 or earlier.
  • Review the plugin’s WordPress.org page and vendor guidance for an updated fixed version.
  • If no fix is available, disable or remove the plugin where business impact permits.
  • Apply standard WordPress hardening and limit administrator exposure to untrusted links.

Validation and detection

  • Confirm whether the plugin is installed on production WordPress sites.
  • Record installed version and compare to affected versions up to 1.6.2.
  • Review web access logs for suspicious requests containing the sscf_name parameter.
  • Validate remediation in staging before re-enabling affected forms.
  • Confirm no affected plugin copies remain in inactive WordPress directories.
