    High [CVE-2026-58222] Samba Vulnerability in NetApp Products

    NTAP-20260821-0018Source published Source updated

    Samba Active Directory Domain Controller versions 4.0.0 and higher are susceptible to a vulnerability which when successfully exploited permits an ordinary authenticated domain user to bypass access checks and query confidential Active Directory attributes (such as KDS root keys) via LDAP Compare requests. Due to a filter injection flaw and trusted execution context, the LDAP Compare operation can be turned into a protected-attribute disclosure oracle. Successful exploitation of this vulnerability could lead to disclosure of sensitive information, addition or modification of data, or Denial of Service (DoS). NetApp reports that one or more additional products remain under investigation; review the canonical advisory for current status. NetApp states there is no workaround available at…

    High [CVE-2026-58222] Samba AD LDAP Compare filter injection and trusted-request confusion disclose protected attributes

    CVE-2026-58222Source published Source updated

    A security flaw combining LDAP filter injection and improper authorization checks was found in Samba Active Directory Domain Controller (AD DC). When processing LDAP Compare requests, Samba fails to properly validate user-supplied attribute names and executes the resulting internal database search in a trusted context, bypassing normal Access Control List (ACL) enforcement. An authenticated low-privilege domain user can exploit these flaws to disclose confidential Active Directory attributes that would normally be inaccessible. The disclosed information may be leveraged to derive sensitive authentication material, potentially leading to privilege escalation and complete domain compromise. For example: In deployments configured with Group Managed Service Accounts (gMSAs), an attacker can…
