CVE-2026-4938 IBM CVE debrief

Who should care

Users of IBM Verify Identity Access 11.0 through 11.0.2, IBM Security Verify Access 10.0 through 10.0.9.1, IBM Verify Identity Access Container 11.0 through 11.0.2, and IBM Security Verify Access Container 10.0 through 10.0.9.1 should review and update permissions for users with read-only privileges, monitor for suspicious activity and unauthorized deployments, and implement compensating controls to restrict modifications and deployments.

Technical summary

CVE-2026-4938 is a vulnerability in IBM Verify Identity Access and IBM Security Verify Access that allows an attacker with read-only privileges to make unauthorized modifications and deployments outside of their assigned permissions. The vulnerability affects multiple versions of these products. The CVSS score is 6.5, and the severity is MEDIUM. Defenders should review and update permissions for users with read-only privileges, monitor for suspicious activity and unauthorized deployments, and implement compensating controls to restrict modifications and deployments.

Defensive priority

Medium priority due to the potential for unauthorized modifications and deployments. Defenders should review and update permissions for users with read-only privileges, monitor for suspicious activity and unauthorized deployments, and implement compensating controls to restrict modifications and deployments. Additionally, defenders should consider implementing compensating controls to restrict modifications and deployments, and track exceptions and retest remediated assets to ensure the vulnerability is properly addressed. Furthermore, defenders should check relevant monitoring, detection, and logs for exposed assets that need extra review, and plan vendor-supported updates or mitigations through normal change control where exposure is confirmed. Finally, defenders should confirm whether affected product deployments exist in managed environments and assign an owner for follow-up, and review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance. Therefore, the defensive priority remains Medium but with an increased emphasis on thorough defensive actions across multiple fronts to mitigate potential impacts effectively and promptly address any unauthorized modifications or deployments that could arise from this vulnerability. Therefore, the defensive priority remains Medium but with an increased emphasis on thorough defensive actions across multiple fronts to mitigate potential impacts effectively and promptly address any unauthorized modifications or deployments that could arise from this vulnerability.
