Deserialization, bypass auth, and TLS gone astray Separate products, separate vendors, separate attack terrain Microsoft, SimpleHelp, Node.js — three different doors of pain Update your SharePoint instance, revoke those OIDC flows Pin your Node.js runtime, verify where your hostname goes The threat intelligence community flagged all three this week Defenders who move fastest are the ones attackers cannot breach [Chorus] Critical vulnerabilities, CVSS scoring high Patch your endpoints, audit your configs, don't let the window slide CVE numbers burning through the threat intelligence feed July third, twenty-twenty-six — remediation is the creed [Outro] Forty-five-six-five-nine, forty-eight-five-five-eight Forty-eight-nine-thirty — memorize them, don't hesitate Three attack surfaces waiting on a system near your team Patch the stack, lock the tokens, validate every TLS stream
