Description
WordPress Core is vulnerable to Remote Code Execution in all versions 6.9 to 7.0.1 via the REST API batch request endpoint (/wp-json/batch/v1). This is due to a route/validation desynchronization that allows a validated sub-request to be dispatched to an unintended callback, bypassing the allow_batch restriction, with attacker-controlled parameters and the target route's input sanitization bypassed, which can be chained with SQL Injection. This may make it possible for attackers to execute code on the server.
Wordfence blocked 676,360 attacks targeting this vulnerability in the past 24 hours.
