Security readout for executives and security teams
Plain-English summary
CVE-2026-25324 affects the WordPress Quiz And Survey Master plugin through version 10.3.4. It is an access-control flaw where a user-controlled key may let someone perform unauthorized actions. The published severity is medium, with limited integrity impact and no stated confidentiality or availability impact.
Executive priority
Treat as a moderate-priority WordPress application risk. It is remotely reachable without login, but published impact is limited. Organizations using this plugin on public websites should identify affected versions promptly and follow vendor guidance once available.
Technical view
The issue is an Insecure Direct Object Reference / CWE-639 authorization bypass in ExpressTech Systems Quiz And Survey Master, package quiz-master-next. CVSS 3.1 is 5.3: network reachable, low complexity, no privileges, no user interaction, unchanged scope, integrity low only.
Likely exposure
Exposure is likely limited to WordPress sites running Quiz And Survey Master versions up to and including 10.3.4. Public-facing WordPress installations have higher practical exposure because the CVSS vector indicates remote unauthenticated reachability.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. The CVSS vector indicates unauthenticated network exploitability, but the documented impact is limited to integrity. No exploit details should be needed to validate exposure.
Researcher notes
Evidence is limited to the CVE record and Patchstack database reference. The affected range is stated as through 10.3.4, but the provided sources do not name a fixed version or detailed remediation. Do not assume active exploitation without additional cited evidence.
Mitigation direction
- Inventory WordPress sites for Quiz And Survey Master plugin usage and version.
- Prioritize sites running Quiz And Survey Master 10.3.4 or earlier.
- Check vendor, WordPress plugin, and Patchstack guidance for a fixed version or official mitigation.
- If no fix is available, consider disabling the plugin where business impact allows.
- Monitor plugin and web logs for unexpected quiz or survey object changes.
Validation and detection
- Confirm the installed plugin slug is quiz-master-next.
- Record the installed Quiz And Survey Master version on each WordPress site.
- Compare versions against the affected range: through 10.3.4.
- Review administrative logs for unauthorized quiz or survey modifications.
- Verify remediation after applying any vendor-provided update or mitigation.
