Exploited in August 2026: 26 KEV Additions, 18 With an EPSS Under 1%
A month of CISA KEV additions read against our CVE catalog: 18 of 26 exploited vulnerabilities score under 1% on EPSS today, 4 had no CVSS score when CISA added them, and CISA gave 18 of them a three-day deadline. The numbers, the method, and what they mean for a patch queue.
CVE-2026-63077 Puts Unauthenticated RCE on Every TeamCity On-Premises Server
A deserialization flaw in the agent polling protocol gives attackers TeamCity server privileges without credentials. JetBrains patched in 2025.11.7 and 2026.1.3 — CISA KEV and a 3-day federal deadline mean hunt now, not after the next release train.
CVE-2026-9198 Gives Unauthenticated RCE in IBM Langflow OSS Agent Control Planes
A SUPERUSER token minted through /api/v1/auto_login chains with Python exec() in /api/v1/validate/code. Langflow 1.10.1 fixes the flaw — but internet-exposed instances need hunting now, not after the next sprint.
CISA KEV Adds Arista VeloCloud and FortiOS Flaws: Why CVSS Is the Wrong Sort Order
On 27 July 2026 CISA added a CVSS 10.0 command injection in Arista VeloCloud Orchestrator and a medium-severity FortiOS patch bypass to KEV. The pairing shows why exposure and persistence beat severity when ordering a patch queue.
