CVE-2026-82069

Improper Redaction of Query Literals in MongoDB Server Query Statistics Serialization on Sharded Cluster Router

Published Sep 8, 2026 CVSS 4.0 · 5.1 Medium EPSS < 1% KEV · Not listed
Description
A security issue in MongoDB Server's query statistics serialization on the router allows users with monitoring privileges to access unredacted search query text from other users' operations. An improper conditional check in the serialization logic causes the data redaction mechanism to be bypassed when processing search queries through the sharded cluster router. This results in sensitive query literals being stored and made accessible through the query statistics interface.
