Security advisory for Bricks Theme 2.4.3 and

Advisory overview

Bricks Theme 2.4.3 and before contains an unauthenticated dynamic-data tag injection vulnerability that allows anonymous attackers to control the urlParams object in the query_result REST endpoint, causing the submitted value to be re-parsed as a Bricks dynamic data tag. Attackers can inject tags such as author_meta:user_pass, author_meta:user_email, or cf_coupon_amount to leak post meta and the post author's user record, including the password hash, without authentication.
