WordPress Patches Pre-Auth Remote Code Execution Flaw in Core API

Versions 6.9.5 and 7.0.2 fix a vulnerability allowing anonymous attackers to execute code on default installations without plugins or credentials.

WordPress released security updates on July 17 to close a critical remote code execution vulnerability that allowed unauthenticated attackers to compromise sites running default configurations of versions 6.9.0 through 6.9.4 and 7.0.0 through 7.0.1. The flaw resides in the REST API batch processing route and requires no installed plugins or valid user credentials to exploit, making it immediately dangerous for any site that has not applied the patch or implemented external mitigations [1]. This follows a summer of compounding supply chain and core vulnerabilities across the WordPress ecosystem, where the window between disclosure and active exploitation has compressed to hours rather than days.
