This affects authenticated users who have read access to the affected collection, enabling them to extract concealed field values via groupBy aggregate queries. This vulnerability allows for the extraction of sensitive information, such as static API tokens and two-factor authentication secrets stored in directus_users, enabling account takeovers and 2FA bypass. The vulnerability was reported on April 4, 2026, and is identified as CVE-2026-35442. Defenders should prioritize upgrading Directus instances to version 11.17.0 or later to mitigate this risk.

Attack Chain

1. Attacker authenticates to a vulnerable Directus instance with valid user credentials.
2. Attacker identifies a collection containing fields with the conceal special type, such as directus_users.
3. Attacker crafts an aggregate query using functions like min or max on the concealed field and includes a groupBy clause. Example: SELECT min(secret_field) FROM collection GROUP BY other_field.
4. The Directus server processes the aggregate query but fails to properly apply the masking logic to the nested results.
5. The server returns the raw, unmasked values of the concealed field in the aggregate query response.
6. The attacker extracts static API tokens and TOTP seeds from the returned data.
7. Attacker uses the extracted API tokens to authenticate as other users, including administrators, bypassing username/password requirements.
8. Attacker uses the extracted TOTP seeds to bypass two-factor authentication for other users, gaining unauthorized access to their accounts.

Impact

Successful exploitation of this vulnerability can lead to complete account takeover, including administrative accounts. Two-factor authentication mechanisms can be bypassed, invalidating this security control. The number of affected organizations depends on the adoption rate of Directus, but all instances running versions prior to 11.17.0 are vulnerable. If the attack succeeds, attackers gain full control over the Directus instance and associated data, potentially leading to data breaches, service disruption, and reputational damage.

Recommendation

• Upgrade Directus to version 11.17.0 or later to patch the vulnerability (CVE-2026-35442).
• Implement a Web Application Firewall (WAF) rule to detect and block aggregate queries targeting concealed fields in sensitive collections. See the Sigma rule example for guidance.
• Monitor Directus application logs for unusual aggregate query patterns, especially those involving groupBy and functions like min or max.

In June 2025, multiple critical vulnerabilities were disclosed. These include CVE-2025-32975, an authentication bypass; CVE-2025-32976, a 2FA bypass; CVE-2025-32977, malicious backup upload; and CVE-2025-32978, license replacement leading to denial of service. The vulnerabilities were discovered during a third-party assessment. As of March 20, 2026, active exploitation has been reported, making immediate patching critical. Versions affected include KACE SMA versions 13.0.385, 13.1.81, 13.2.183, 14.0.341, and 14.1.101. Successful exploitation can lead to complete system compromise, impacting enterprise security and operations.

Attack Chain

1. Unauthenticated Request (CVE-2025-32975): An attacker sends a crafted request to the KACE SMA server, exploiting the improper authentication handling in the SSO mechanism.
2. Authentication Bypass: The server fails to properly validate the request, allowing the attacker to bypass authentication and impersonate a legitimate user, gaining unauthorized access to the system.
3. 2FA Bypass (CVE-2025-32976): If the attacker has valid credentials, they exploit a logic flaw in the two-factor authentication implementation to bypass TOTP-based 2FA requirements.
4. Privilege Escalation: Using the bypassed authentication, the attacker gains access to administrative privileges within the KACE SMA.
5. Malicious Backup Upload (CVE-2025-32977): An unauthenticated attacker uploads a malicious backup file to the system, exploiting weaknesses in the cryptographic signature validation process.
6. System Compromise: The malicious backup content is processed, compromising the system’s integrity and potentially allowing the attacker to execute arbitrary code.
7. License Replacement (CVE-2025-32978): The attacker uses a web interface intended for license renewal to replace valid system licenses with expired or trial licenses.
8. Denial of Service: The replacement of valid licenses causes a denial of service, disrupting normal operations and preventing legitimate users from accessing the system.

Impact

Successful exploitation of these vulnerabilities allows attackers to gain complete control over the KACE SMA, leading to the compromise of managed endpoints. The denial-of-service vulnerability disrupts IT operations. While the exact number of victims is unknown, the widespread use of KACE SMA across various sectors suggests a broad potential impact. Active exploitation reported as of March 2026 increases the urgency.

Recommendation

• Apply the patches released by Quest for KACE SMA versions 13.0.385, 13.1.81, 13.2.183, 14.0.341 (Patch 5), 14.1.101 (Patch 4) to remediate CVE-2025-32975, CVE-2025-32976, CVE-2025-32977, and CVE-2025-32978.
• Upscale monitoring and detection capabilities to identify any related suspicious activity as recommended by CCB.
• Implement the Sigma rule “Detect Unauthenticated Access Attempts to KACE SMA” to identify potential exploitation attempts targeting CVE-2025-32975.
• Review web server logs for suspicious file uploads to detect potential exploitation of CVE-2025-32977.
