VERY IMPORTANT

Two chained vulnerabilities in WordPress Core enable unauthenticated remote code execution on installations running versions 6.9.0 through 6.9.4 or 7.0.0 through 7.0.1. The first flaw affects the REST API batch endpoint validation, while the second is a SQL injection in the post query layer. When exploited together, attackers achieve full administrator access and deploy webshells. Active exploitation has been confirmed with a public proof-of-concept available. Attackers conduct mass scanning followed by automated compromise sequences that create unauthorized administrator accounts with w2s_ prefixes, upload malicious plugins, and establish persistent remote access. Observed incidents show multiple exploitation attempts before successful compromise. Fixed versions 6.9.5 and 7.0.2 are available, with forced auto-updates deployed. Organizations should patch immediately or implement WAF rules blocking anonymous access to the batch endpoint.
