Critical SimpleHelp RMM authentication bypass exploited

🔒 A critical authentication bypass in SimpleHelp's RMM software was exploited to forge a technician login token and deliver two previously unseen malware families. Researchers at Blackpoint Cyber found the flaw (CVE-2026-48558) allowed unauthenticated token forgery by skipping cryptographic signature checks in OpenID Connect. Attackers abused built-in file transfer and remote execution to deploy a Node.js loader named TaskWeaver and a cross-platform stealer called Djinn Stealer. The vulnerability received a CVSS score of 10 and was patched in late May; CISA added it to KEV on June 29.
