CVE-2023-3249 - Web3 Authentication Plugin

CVE-2023-3249

The Web3 – Crypto wallet Login & NFT token gating plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 2.6.0. This is due to incorrect authentication checking in the 'hidden_form_data' function. This makes it possible for authenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the username.

Potential Impact

Severity is CRITICAL (CVSS 9.8). Depending on deployment context, affected components may be exposed to unauthorized actions or data integrity risk.

Exploitability Assessment

Exploitability is assessed as Very High based on remote code execution potential, low-bar exploit prerequisites.

Primary risk drivers: remote code execution potential, low-bar exploit prerequisites

Mitigation Recommendations

Validate affected product versions, prioritize patching, and monitor references for vendor remediation guidance. If immediate patching is not possible, apply compensating controls and limit exposure of vulnerable surfaces.

Detection & Monitoring

Track authentication anomalies, unexpected file writes, and suspicious plugin API activity around affected components.

Business Impact Lens

Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.
