Resolved
From 2023-03-20 16:30 UTC to 2023-03-20 23:59 UTC, for a portion of HTTP requests with JSON request bodies, WAF managed rules (previous version) did not process rules and allowed the request to proceed to the origin. Requests without requests bodies, or requests with request bodies that were not JSON, were not impacted and WAF managed rules (previous version) continued to operate normally.
