AI Analysis
Technical Summary
CVE-2026-5722 is an authentication bypass vulnerability in MoreConvert Pro for WordPress. The vulnerability exists because the guest waitlist verification flow fails to invalidate or regenerate verification tokens when the customer email address changes. An attacker can obtain a valid guest verification token for an attacker-controlled email, then change the guest customer email to a target account's email via the public waitlist flow, and reuse the original verification link to authenticate as the target user, including administrators. This vulnerability affects all versions up to and including 1.9.14 and has a CVSS 3.1 base score of 9.8, indicating critical impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows unauthenticated attackers to bypass authentication controls and gain access to accounts of existing users, including administrators. This compromises confidentiality, integrity, and availability of the affected WordPress site and its data. The vulnerability can lead to full administrative control over the site.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are currently available. Until a patch is released, users should consider disabling the MoreConvert Pro plugin or restricting access to the guest waitlist verification functionality to trusted users only.
