CVE-2026-92626 Control iD CVE debrief

Who should care

Defenders responsible for Control iD iDSecure systems, particularly those using versions prior to 4.8.3.0, should assess exposure and prioritize patching or mitigation to prevent potential DoS attacks.

Why it matters

CVE-2026-92626 is a high-severity vulnerability in Control iD iDSecure that could lead to unauthenticated Denial of Service (DoS) attacks. Defenders should prioritize patching or mitigating this vulnerability to prevent potential DoS attacks. Inventory checks and monitoring for exploitation attempts are recommended. The corpus does not provide information on exploitation or affected versions beyond Control iD iDSecure versions prior to 4.8.3.0.

• Potential Denial of Service (DoS) attacks against Control iD iDSecure systems
• Need for inventory checks to identify affected systems
• Requirement for patching or mitigating the vulnerability to prevent exploitation
• Potential impact on system availability if exploited

Technical summary

The /api/dguardintegration/dguardVersion endpoint in Control iD iDSecure versions prior to 4.8.3.0 is vulnerable to an unauthenticated Denial of Service (DoS) attack. An unhandled null reference exception occurs when the DGuard integration login state is unset, potentially terminating the iDSecure process. This vulnerability allows attackers to cause a denial of service by exploiting the endpoint, which can lead to system unavailability. Defenders should prioritize patching or mitigating this vulnerability to prevent potential DoS attacks. Inventory checks and monitoring for exploitation attempts are recommended to identify and protect affected systems.

Defensive priority

Defenders should prioritize patching or mitigating this vulnerability to prevent potential DoS attacks. Inventory checks and monitoring for exploitation attempts are recommended.

Recommended defensive actions

• Patch or upgrade Control iD iDSecure to version 4.8.3.0 or later
• Implement monitoring and logging to detect potential exploitation attempts
• Perform inventory checks to identify affected systems
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The vulnerability was reported by Tenable and is documented in the NVD vulnerability detail page. However, the corpus does not provide information on exploitation or affected versions beyond Control iD iDSecure versions prior to 4.8.3.0.
