CVE-2026-66246Network attack vector

Unauthorized data changes via broken access control

Published Oct 1, 2026 · Updated Oct 1, 2026

Broken access control in HCL iControl 4.5.0 allows attackers to modify or delete sensitive application data through unauthorized requests. The source record identifies missing authentication checks or insecure direct object references but does not identify the affected endpoint or the exact authorization operation that fails. Access requirements are unspecified, so unauthenticated reachability and the extent of privilege escalation remain unconfirmed.
