CVE-2026-16604: Passster exposes password-protected block content in public responses

Passster before 4.3.6 includes password-protected block content in the public page response before it verifies the supplied password. An unauthenticated visitor can inspect the returned HTML or page data and recover the protected material without knowing the password. This unscored record received deeper review because it is an unauthenticated content-disclosure primitive. The CNA does not identify the response field or markup location that contains the hidden content.
