CVE-2026-85983 · Severity: high · CVSS 7.8 · Published 2026-09-08

The Auth0 AD/LDAP Connector, a service used to integrate Active Directory and LDAP systems with Auth0 identity management, contains a configuration handling vulnerability. A low-privileged user with local access to the host system can modify the connector's configuration file, and upon service restart, this can lead to arbitrary code execution with the service account's privileges—potentially compromising the entire authentication infrastructure and exposing directory data.

## Technical details

The vulnerability is a code injection flaw (CWE-94) stemming from improper processing of configuration values during Auth0 AD/LDAP Connector service startup. An authenticated, low-privileged local user can write to or modify the connector's configuration file before the service restarts. When the service processes the modified configuration, unsanitized input is used in code generation or execution, allowing arbitrary code execution under the service account privileges. The attack requires local host access and service restart but no network traversal. A fix is available in version 8.00 or later of the auth0/ad-ldap-connector.
