CVE-2026-82053: CWE-863: Incorrect Authorization in MongoDB MongoDB Server
A security issue exists in MongoDB's LDAP authorization integration where pooled LDAP connections can retain stale authentication identities after user authentication under certain configurations. Subsequent authorization queries may execute under an unintended LDAP identity rather than the expected one. This can result in incorrect role assignments based on the LDAP directory's access control configuration, potentially allowing an authenticated user to acquire elevated privileges that were not intended by the deployment's authorization policy.
AI Analysis
Technical Summary
This vulnerability (CWE-863) in MongoDB Server affects the LDAP authorization integration. When LDAP connections are pooled, stale authentication identities may persist after a user authenticates. As a result, subsequent authorization queries might execute under an unintended LDAP identity rather than the authenticated user's identity. This can lead to incorrect role assignments based on the LDAP directory's access control settings, allowing privilege escalation beyond the intended authorization scope. The affected versions explicitly include 7.0.0, 8.0.0, and 8.3.0. The CVSS 4.0 base score is 7.6, indicating a high severity with network attack vector, low attack complexity, and partial privileges required.
Potential Impact
An authenticated user may gain elevated privileges due to incorrect authorization decisions caused by stale LDAP identities in pooled connections. This undermines the intended access control policies and can lead to unauthorized access to sensitive data or administrative functions within MongoDB Server.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is currently documented. Users should monitor MongoDB's official advisories for updates and consider reviewing LDAP connection pooling configurations as a precaution until a fix is available.
