CVE-2026-15963Network attack vector

Data disclosure via unsanitized category IDs

Published Aug 16, 2026 · Updated Aug 16, 2026

SQL injection in Quiz and Survey Master before 11.2.2 allows remote authenticated users to read database contents via randon_category. In the quiz rendering path referenced by the CVE record, the plugin passes category IDs from the randon_category quiz option into a question-selection SQL query without sanitizing them before query construction. Exploitation requires Custom-level or higher access to quiz options, and the published impact is limited to database data extraction rather than direct data modification or service interruption.
