Akamai has disclosed CVE-2026-34354, a local privilege escalation vulnerability in the Guardicore Platform Agent and Zero Trust Client for macOS and Linux. The vulnerability leverages an unauthenticated IPC socket and a TOCTOU flaw to make root-owned files world-writable, alongside a secondary command injection vector in a diagnostic tool.
The Canadian Centre for Cyber Security released a daily digest highlighting five security advisories. Notably, Ivanti Endpoint Manager Mobile (EPMM) contains an actively exploited vulnerability (CVE-2026-6973), and critical updates were issued for Spring Cloud Config, VM2 Node.js library, Mozilla Firefox, and multiple Broadcom VMware Tanzu products.
Threat actors are actively deploying Nightmare-Eclipse proof-of-concept tools, including BlueHammer, RedSun, and UnDefend, in real-world intrusions to exploit Windows Defender race conditions for privilege escalation. The attacks, likely originating from compromised FortiGate VPN access, culminate in the deployment of BeigeBurrow, a Go-based reverse tunnel agent used for persistent command and control.
CVE-2026-31979 is a high-severity local privilege escalation vulnerability in the Himmelblau Linux-to-Azure integration suite. By exploiting a time-of-check to time-of-use (TOCTOU) symlink race condition in the shared /tmp directory, an unprivileged local attacker can hijack root-level file operations to take ownership of critical system files, potentially enabling lateral movement into cloud infrastructure.
