5DescriptionCVE.org
The Smart Post WordPress plugin before 4.0.8 does not check whether a post is password protected before returning its content and its stored password through an unauthenticated AJAX action, allowing unauthenticated users to read protected post content and the password that guards it.
AnalysisAI
Unauthenticated information disclosure in the Smart Post WordPress plugin (versions prior to 4.0.8) exposes both the content of password-protected posts and the passwords themselves via an unprotected AJAX endpoint. Any unauthenticated remote user can query the endpoint to bypass WordPress's native post-password protection mechanism entirely, retrieving guarded content without knowing the password - and also harvesting the password itself for reuse. …
