CVE-2026-16603
The Passster WordPress plugin before 4.3.6 does not enforce its category-based content protection on the WordPress REST API, allowing unauthenticated users to read the full content, title, and excerpt of category-locked posts through the core REST API.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.32%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
