A vulnerability in MongoDB Server's Queryable Encryption maintenance operations allows an authenticated user with privileges on one encrypted collection to modify or destroy data in a different collection. This occurs due to insufficient validation of internal metadata references before performing operations on other namespaces. The issue does not affect confidentiality but impacts integrity and availability of data. No patch information is currently provided.
AI Analysis
Technical Summary
CVE-2026-18712 describes a security flaw in MongoDB Server's Queryable Encryption feature where maintenance operations fail to properly validate internal metadata references. An authenticated user with privileges on one encrypted collection can exploit this to cause unauthorized modification or destruction of data in another collection. This is classified under CWE-863 (Incorrect Authorization). The vulnerability has a CVSS v3.1 score of 8.1, indicating high severity with network attack vector, low attack complexity, privileges required, no user interaction, unchanged scope, no confidentiality impact, but high integrity and availability impact.
Potential Impact
The vulnerability allows an authenticated user with privileges on one encrypted collection to perform unauthorized modifications or destruction of data in a different collection. This compromises data integrity and availability but does not affect confidentiality. 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. Until a fix is available, restrict privileges carefully to minimize risk of unauthorized operations across collections.
