WordPress Core Interpretation Conflict Vulnerability

WordPress · Core

Summary

A route confusion flaw in WordPress Core's REST API batch endpoint, affecting the 6.9.x and 7.0.x release branches before their fixed versions, is what lets this issue be leveraged. An unauthenticated remote attacker, requiring no user interaction and using only network access, could chain it with a separate SQL injection in the author__not_in WP_Query parameter to run SQL injection and potentially achieve remote code execution.
