CVE-2026-9599: Tectite Forms <= 1.3 - Cross-Site Request Forgery to Settings Update

The Tectite Forms plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.3. This is due to missing or incorrect nonce validation on the admin_init function. This makes it possible for unauthenticated attackers to modify the plugin's settings, including the tectite_forms_button option, via a forged request via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Analyst readout for executives and security teams

Plain-English summary

CVE-2026-9599 affects the WordPress Tectite Forms plugin through version 1.3. A malicious site or link could trick a logged-in administrator into changing plugin settings. The known impact is limited settings integrity loss, not data theft or server takeover.

Executive priority

Treat this as a medium-priority WordPress plugin issue. It is not described as actively exploited or high-impact, but it can let attackers alter business-facing form settings if an administrator is tricked.

Technical view

The issue is CWE-352 cross-site request forgery caused by missing or incorrect nonce validation around an admin_init settings path. An unauthenticated attacker still needs administrator interaction. The cited impact is modification of plugin options, including tectite_forms_button. CVSS is 4.3, with low integrity impact only.

Likely exposure

Exposure is limited to WordPress sites running Tectite Forms up to and including version 1.3. The CVE affected-version metadata appears incomplete, so validate against installed plugin name and version, not only automated CPE matching.

Exploitation context

The source bundle does not cite active exploitation, and KEV is false. Exploitation requires social engineering a logged-in site administrator into triggering a forged request. No source claims public weaponization or broad exploitation.

Researcher notes

Source evidence identifies missing or incorrect nonce validation on admin_init and references WordPress plugin code paths. The bundle does not provide a patch commit, fixed version, or mitigation beyond the vulnerability description, so remediation should track vendor guidance.

Mitigation direction

  • Check Wordfence and the plugin vendor for fixed-version guidance.
  • Update Tectite Forms if a patched release is available.
  • Disable or remove the plugin if no fix exists and exposure is material.
  • Reduce administrator exposure to untrusted links while the plugin remains installed.
  • Review plugin settings for unauthorized changes after administrator browsing incidents.

Validation and detection

  • Inventory WordPress sites for the Tectite Forms plugin.
  • Confirm installed Tectite Forms versions, especially 1.3 or earlier.
  • Review plugin configuration for unexpected tectite_forms_button changes.
  • Check security monitoring for administrator sessions followed by plugin setting changes.
  • Verify whether vendor or Wordfence guidance names a patched version.
