CVE-2026-82069Network attack vector

Authenticated query disclosure via skipped mongos redaction

Published Sep 8, 2026 · Updated Sep 8, 2026

Information disclosure in MongoDB Server 8.3.0 through 8.3.8 allows remote authenticated users to read other users' search query literals. An improper condition in mongos query-statistics serialization skips redaction for search query shapes and stores their raw literals. Access requires monitoring privileges on a sharded-cluster router; the reported consequence is disclosure through the query-statistics interface.
