CVE-2026-82053: CWE-863: Incorrect Authorization in MongoDB MongoDB Server
Description
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.

Technical Analysis
This vulnerability arises from incorrect authorization handling in MongoDB Server's LDAP integration. When LDAP connections are pooled, stale authentication identities may persist after a user authenticates. As a result, subsequent authorization queries might execute with an incorrect LDAP identity, leading to improper role assignments based on the LDAP directory's access control. This can allow an authenticated user to gain elevated privileges not intended by the deployment's authorization policy. The issue affects MongoDB Server versions >=7.0.0 <7.0.41, >=8.0.0 <8.0.30, and >=8.3.0 <8.3.9. The CVSS 4.0 score is 7.6, indicating high severity.
Potential Impact
An authenticated user may receive elevated privileges due to authorization queries executing under an unintended LDAP identity. This could lead to unauthorized access to roles and permissions configured in the LDAP directory, violating the intended access control policies.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official patch or fix information is provided in the available data. Until a fix is available, review LDAP integration configurations and consider limiting LDAP connection pooling if possible to reduce risk.
