The Quiz and Survey Master - Security Vulnerability (CVE-2026-103917)

Q: Am I affected by this vulnerability?

You are affected if your site runs The Quiz and Survey Master. No account is needed to exploit this, so a public site is reachable by anyone.

Q: How do I fix it?

Update The Quiz and Survey Master to the latest available version. Where the vendor has not yet published a fix, remove or disable the plugin until they do. Until you can update, Request / payload inspection (WAF) in Hack Halt ProSecure contains this class of attack at the request layer.

Q: What can an attacker actually do?

This is a Cross-Site Request Forgery (CSRF) flaw. An attacker who exploits it can make a logged-in administrator perform an action just by visiting a page.

Vulnerability CVE-2026-103917 PLUGIN quiz-and-survey-master MEDIUM

The The Quiz and Survey Master (QSM) – Quiz Maker & Survey Maker plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 11.2.7. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes. The submission nonce is dispensed to any unauthenticated caller by the public wp_ajax_nopriv_qsm_create_quiz_nonce endpoint, meaning it functions as a CSRF token rather than an authorization barrier and imposes no meaningful obstacle to exploitation.

Mitigation Recommendations

Validate affected product versions, prioritize patching, and monitor references for vendor remediation guidance. If immediate patching is not possible, apply compensating controls and limit exposure of vulnerable surfaces.

Detection & Monitoring

Track authentication anomalies, unexpected file writes, and suspicious plugin API activity around affected components.

What to do about this

Patch promptly The consequence is significant even where an attacker needs a foothold first.

Fix it

Update The Quiz and Survey Master to the latest available version.

Where the vendor has not published a fix yet, disable the plugin until they do.

Cannot update today? Request / payload inspection (WAF) in Hack Halt ProSecure blocks this class of attack before WordPress processes the request.

Inspect request parameters and bodies for injection, traversal and file-inclusion payloads, and refuse the request rather than logging it.
