CVE-2026-14821Network attack vector

Contributor-level template deletion via missing capability check

Published Jul 28, 2026 · Updated Jul 28, 2026

Missing authorization in Quiz and Survey Master before 11.1.5 allows remote authenticated users to delete arbitrary output templates. The output-template deletion endpoint executes the requested deletion without checking the caller's WordPress capability. Contributor-level access is sufficient, and exploitation removes quiz or survey output templates rather than altering broader site configuration.
