CVE-2026-82069: CWE-212: Improper Removal of Sensitive Information Before Storage or Transfer in MongoDB MongoDB Server
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.
AI Analysis
Technical Summary
This vulnerability (CWE-212) in MongoDB Server 8.3.0 arises from an improper conditional check in the serialization logic of query statistics on the router component. The flaw causes the data redaction mechanism to be bypassed, allowing users with monitoring privileges to see sensitive query literals from other users' operations. The issue specifically affects the sharded cluster router's handling of search queries, resulting in sensitive query text being stored and accessible via the query statistics interface.
Potential Impact
Users with monitoring privileges can access unredacted, sensitive search query text from other users, potentially exposing confidential information. The vulnerability does not allow privilege escalation or remote code execution but leaks sensitive data through the query statistics interface. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround has been published. Until a patch is available, limit monitoring privileges to trusted users only to reduce exposure risk.
