Cybersecurity Laurenceo Intelligence CISA · United States

A state-linked actor is still exploiting long-known flaws, which suggests that unpatched legacy and edge systems remain a dependable way in. The three-day federal deadline gives private organisations a useful benchmark for how fast to act on these specific entries. Asset inventories should be checked for forgotten appliances and self-hosted development tools.

What Happened

The Hacker News reported that on 8 October 2026 CISA added five vulnerabilities to its Known Exploited Vulnerabilities catalog after they were abused by the China-linked actor Flax Typhoon. The flaws include older vulnerabilities in GNU Bash (Shellshock), Ivanti Pulse Connect Secure and GitLab. US federal agencies must patch the affected software or stop using it by 11 October 2026.
