Technical Analysis
The Smart Post WordPress plugin versions before 4.0.8 contain an information exposure vulnerability (CWE-200) where an unauthenticated AJAX action returns the content of password-protected posts along with the stored password without verifying if the post is protected. This allows any unauthenticated user to read protected content and obtain the password that guards it.
Potential Impact
An attacker can access sensitive content intended to be protected by a password without authentication, leading to unauthorized disclosure of information. The vulnerability does not affect integrity or availability but compromises confidentiality.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the AJAX endpoint or disable the Smart Post plugin if possible to prevent unauthorized access to protected content.
