Security readout for executives and security teams

Plain-English summary

CVE-2026-25329 affects the WordPress Quiz And Survey Master plugin through version 10.3.4. It is a broken access control issue that may let a logged-in user perform an action they should not be allowed to perform. The reported impact is limited to integrity, not data theft or service outage.

Executive priority

Treat as a normal-priority WordPress plugin remediation item. Prioritize sites with public registration, many low-trust users, or business-critical quizzes and surveys. It does not currently justify emergency response based on the provided evidence.

Technical view

The issue is CWE-862 Missing Authorization in ExpressTech Systems Quiz And Survey Master, package quiz-master-next. CVSS 3.1 is 4.3: network reachable, low complexity, low privileges required, no user interaction, unchanged scope, low integrity impact, no confidentiality or availability impact. Affected versions are listed as through 10.3.4.

Likely exposure

Exposure is limited to WordPress sites running Quiz And Survey Master version 10.3.4 or earlier. Because exploitation requires low privileges, sites allowing subscriber, customer, student, or other low-trust logins may have higher practical risk.

Exploitation context

The provided sources do not report active exploitation, and the CVE is not listed as KEV in the supplied data. The vulnerability is remotely reachable but requires an authenticated user account. No exploit details are provided in the source bundle.

Researcher notes

Evidence is limited to the CVE record and Patchstack database entry. The affected range is through 10.3.4, but the supplied data does not name a fixed version or specific vulnerable function. Avoid assuming exploitability beyond authenticated broken access control with low integrity impact.

Mitigation direction

  • Inventory WordPress sites for the Quiz And Survey Master plugin.
  • Identify installations running version 10.3.4 or earlier.
  • Check vendor, WordPress.org, or Patchstack guidance for fixed versions or official mitigations.
  • Restrict untrusted user registration where business requirements allow.
  • Review low-privilege WordPress roles assigned to external users.

Validation and detection

  • Confirm plugin presence and version in WordPress administration or asset inventory.
  • Verify whether affected sites allow low-privilege user login.
  • Check Patchstack and CVE records for updated remediation details.
  • Review recent changes by low-privilege users for unexpected quiz or survey modifications.
  • Document compensating controls if an update is not yet available.
