An authenticated user with write privileges on a Queryable Encryption-enabled collection may be able to modify internal encryption metadata fields… (CVE-2026-13062)
An authenticated user with write privileges on a Queryable Encryption-enabled collection in a MongoDB sharded cluster may modify internal encryption metadata fields that should be controlled by the server. This manipulation can corrupt the correctness of encrypted queries, potentially impacting data integrity and query reliability.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-13062) allows an authenticated user who has write access on a Queryable Encryption-enabled collection to alter internal encryption metadata fields by sending crafted write commands through the mongos router in a sharded MongoDB cluster. These metadata fields are intended to be managed exclusively by the server to ensure the integrity and correctness of encrypted queries. Unauthorized modification can lead to corruption in encrypted query processing, undermining the reliability of encrypted data operations.
Potential Impact
The impact is corruption of encrypted query correctness, which may cause encrypted queries to return incorrect results or behave unpredictably. This affects data integrity and the trustworthiness of encrypted query operations in affected MongoDB deployments. There is no indication of privilege escalation or data disclosure from the provided information.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict write privileges on Queryable Encryption-enabled collections to only fully trusted users. Monitor vendor advisories for updates regarding patches or official mitigations.
