AI Analysis
Technical Summary
CVE-2026-16290 is a missing authorization vulnerability (CWE-862) in the ProfileGrid WordPress plugin versions prior to 6.0.0.0. The plugin fails to perform authorization checks before returning a group's member list and registers the handler for unauthenticated users.
