Flowise deleted its CSV Agent after the regex guarding model-written code failed repeatedly

Flowise fixed a CVSS 9.8 remote-code bug in its CSV Agent with a stricter regex, then saw that filter fail through five more CVEs. It deleted the feature in June, and the patch history is a case against trusting a string filter to vet model-written code.

Windows DNS Server's 9.8 bug takes one unauthenticated packet to port 53

Microsoft patched CVE-2026-69730, a CVSS 9.8 remote code execution flaw in the Windows DNS Server role reachable with one unauthenticated packet to port 53. In most Active Directory shops that role runs on the domain controller, so the box answering on port 53 also holds the identity database.

Two exploited Windows privilege escalations should go first in September's record Patch Tuesday

Microsoft's record September release fixed up to 997 CVEs, including two local escalations to SYSTEM that attackers used before the patch shipped. A 7.8 score understates the step that turns a phishing foothold into control of the machine, so both go ahead of the 9.8 remote flaws.

Ten drops since April 2026, the latest handing any local user SYSTEM on fully patched Windows 11. The next scheduled fix can be 28 days out, so mitigation has to be a day-one job.
