CVE-2026-104047 · Severity: medium · CVSS 5.3 · Published 2026-10-06

SSSD (System Security Services Daemon) is a local authentication and directory access service used on Linux systems. When configured to integrate with Microsoft Entra ID, the service fails to properly validate user-supplied search input before using it in directory queries. A local user with low-level access can craft malicious search requests to bypass query logic and retrieve sensitive directory information they should not have access to.

Technologies: [Red Hat SSSD](https://junglewise.ai/threats/technologies/red-hat-sssd). Vendors: [Red Hat](https://junglewise.ai/threats/vendors/red-hat).

## Technical details

A CWE-140 improper delimiter neutralization flaw exists in SSSD's Microsoft Entra ID provider, where search inputs are not sanitized before incorporation into LDAP-style directory query filters. An authenticated local user (low privilege) can submit a crafted lookup request to manipulate query filters and retrieve unauthorized directory records or cause processing overhead, without requiring user interaction or remote network access. Confidentiality and integrity impact are limited; no code execution or privilege escalation is possible.
