Miggo AIMiggo AIMiggo AIRoot Cause AnalysisThe vulnerability stems from the original server ACL checking implementation in server_matches_acl_event, which processed allow/deny lists by converting glob patterns to regexes on every check. The commit f84da3c introduced caching and Rust-based pre-compilation, indicating the previous implementation lacked throttling/caching. The function was removed in the patch and replaced with a cached evaluator, confirming it was the source of the resource allocation vulnerability.
