Published: 01 October 2024
Summary
CVE-2024-9106 is a critical-severity Authentication Bypass Using an Alternate Path or Channel (CWE-288) vulnerability in Wordpress (inferred from references). Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 2.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The Wechat Social login plugin for WordPress is vulnerable to authentication bypass in versions up to and including 1.3.0. The flaw stems from insufficient verification of the user identity supplied during social login flows, combined with a default empty value for the app secret. This condition is tracked as CWE-288 and carries a CVSS 3.1 score of 9.8.
Unauthenticated attackers who can supply a valid user ID are able to log in as any existing account on the site, including administrator accounts, without providing credentials or completing normal social authentication. Exploitation requires only that the plugin’s app secret remains unset; once that precondition is met, the bypass can be triggered remotely over the network.
Public references include the Wordfence threat-intelligence entry for the vulnerability and the affected plugin source file that implements the QQ social channel login logic. The EPSS score has remained flat at its current peak of 0.4118 since disclosure, indicating no material increase in observed exploitation interest.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Authorizing remote access reduces the ability to bypass authentication via unauthorized alternate remote channels.
Users can identify logons via alternate paths or channels by reviewing the previous logon time.
Adaptive requirements can apply across access paths, reducing the ability to bypass authentication via alternate channels or paths.
Centralized IdPs close alternate authentication paths that enable bypass.
Enforces authentication for non-organizational users, making it harder to bypass via alternate paths or channels.
Requires authentication to occur exclusively over the isolated trusted path, directly preventing bypass via alternate or untrusted channels.
