ShieldCrash - ShieldBreak/CVE-2026-69414 bypass

ShieldCrash (CVE-2026-XXXXX) is a critical improper-permission-validation vulnerability that allows any authenticated low-privileged user to escalate to SYSTEM/root privileges on affected hosts. By exploiting a flaw in the way the target component validates access tokens during a specific service-restart routine, an attacker can bypass privilege boundaries and load an arbitrary payload with elevated rights, effectively taking full control of the machine.
