CVE-2026-18470: CWE-200 Information Exposure in Login & Register Forms
A vulnerability in the Login & Register Forms WordPress plugin before version 4.0.2 allows unauthenticated users to obtain registered users' email addresses, including those of administrators. This occurs because the plugin does not verify that a password reset request originates from the account owner and fails to properly redact email addresses in its response.
AI Analysis
Technical Summary
CVE-2026-18470 is an information exposure vulnerability (CWE-200) in the Login & Register Forms WordPress plugin versions before 4.0.2. The flaw arises from the plugin's failure to verify ownership of password reset requests and inadequate redaction of email addresses in responses. This allows unauthenticated attackers to retrieve email addresses of registered users, including administrators, potentially facilitating further targeted attacks.
Potential Impact
The vulnerability exposes registered users' email addresses to unauthenticated attackers. This exposure can lead to increased risk of phishing or social engineering attacks targeting those users, especially administrators. There is no direct impact on data integrity or availability reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vulnerability affects versions before 4.0.2, upgrading to version 4.0.2 or later is likely recommended once official fixes are released. Until then, monitor vendor communications for updates.
