What happened
October 2026 security news roundup covering critical vulnerabilities and active exploitation across UEFI/EDK2 firmware, PHP, Plex, Zimbra, TLS certificate infrastructure, Tor exit nodes, and Internet-exposed IoT systems. It also highlights phishing, mercenary spyware delivered through zero-click exploits, AI-agent abuse and protocol risks, data breaches, and privacy failures. Multiple reports describe remotely exploitable flaws, certificate authority or registry compromises, credential interception, malware deployment, and theft of sensitive data.
