CVE-2026-24962: 
WordPress vulnerability analysis and mitigation

CVE-2026-24962 is a Cross-Site Request Forgery (CSRF) vulnerability in the Brainstorm Force Sigmize WordPress plugin, affecting all versions up to and including 0.0.9. The vulnerability was reported by researcher Nguyen Ba Khanh on December 4, 2025, and publicly disclosed on February 7, 2026. It carries a CVSS v3.1 base score of 4.3 (Medium) (Patchstack).

The vulnerability is classified as CWE-352 (Cross-Site Request Forgery), arising from insufficient or absent CSRF token validation in the Sigmize plugin's request handling. An unauthenticated attacker can craft a malicious web page or link that, when visited by an authenticated WordPress user, causes the victim's browser to submit unauthorized requests on their behalf. Exploitation requires user interaction — specifically, a privileged user must be tricked into clicking a malicious link or visiting a crafted page while authenticated (Patchstack).

Successful exploitation allows an attacker to force higher-privileged WordPress users to execute unwanted actions under their current authentication context, resulting in a low integrity impact with no confidentiality or availability impact. The scope is limited to the affected WordPress installation, and the vulnerability does not directly enable remote code execution or data exfiltration. However, depending on the plugin's functionality, unauthorized state-changing actions (such as modifying plugin settings) could be performed on behalf of the victim (Patchstack).

No public proof-of-concept exploit code or in-the-wild exploitation has been reported for this vulnerability. The EPSS score is extremely low at 0.000080, indicating a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Patchstack notes that while CSRF vulnerabilities of this type are sometimes used in mass-exploit campaigns targeting WordPress sites, this specific issue is assessed as low priority and unlikely to be exploited (Patchstack).

1. Reconnaissance: Identify WordPress sites running the Sigmize plugin version 0.0.9 or earlier, using tools like WPScan or Shodan.
2. Craft malicious request: Analyze the Sigmize plugin's state-changing endpoints (e.g., settings update forms) to identify actions that lack CSRF token validation.
3. Create malicious page: Build an HTML page containing a hidden form or JavaScript that automatically submits a forged request to the target WordPress site's vulnerable Sigmize endpoint.
4. Social engineering: Deliver the malicious link or page to an authenticated WordPress administrator or privileged user via phishing email, comment, or other social engineering vector.
5. Trigger exploitation: When the victim visits the malicious page while logged into their WordPress site, their browser automatically submits the forged request, causing the unintended action to execute under their privileges (Patchstack).

• Logs: WordPress access logs showing unexpected POST requests to Sigmize plugin endpoints from unusual referrer URLs or with no referrer header, particularly from authenticated sessions.
• Logs: Admin action logs reflecting configuration changes or plugin actions that the administrator does not recall performing.
• Network: Requests to WordPress admin-ajax.php or plugin-specific endpoints originating from external or unexpected referrer domains.

The vulnerability is patched in Sigmize version 0.0.10. Site administrators should update the Sigmize plugin to version 0.0.10 or later immediately. If an immediate update is not possible, consider deactivating the plugin until the update can be applied, or consult your hosting provider. Patchstack users can enable auto-update for vulnerable plugins to automate remediation (Patchstack).
