CVE-2023-26524Network attack vector

Forced data modification via undisclosed CSRF mechanism

Published Nov 12, 2023 · Updated Apr 28, 2026

Cross-site request forgery in ExpressTech Systems Quiz and Survey Master 8.0.10 and earlier allows remote attackers to alter data. The CNA and referenced advisory do not identify the affected request handler, forged action, or missing request-validation operation. Exploitation requires an authenticated WordPress user to interact with attacker-controlled content; the CNA bounds the reported effect to low-integrity modification, without confidentiality or availability impact.
