Insikt Group flagged 82 high-impact CVEs for October 2026, 52 with a Very Critical score, and a table of 69 actively exploited or weaponised issues, with Citrix and Microsoft making up about 15%. Notable entries include PHP2Shell (CVE-2026-109618 and CVE-2026-109619, PHP), Palo Alto PAN-OS, Fortinet, Ivanti Connect Secure and Cisco products. Defenders should prioritise KEV-listed items and deploy the Nuclei templates where relevant, and verify any public PoC before testing, as the PoCs were not validated by the authors.
