Three Active Fires, One 'Triage by Exploitability' Rule
The 622-CVE headline is noise; the signal is four internet-facing and identity-tier exploitation paths that outrank your entire backlog.
Triage by exploitability, not headline volume. This ledger leaves no other option. The SonicWall SMA1000 flaw is the sharpest: an unauthenticated, internet-facing SSRF scored CVSS 10, confirmed in multiple incidents, with no workaround but the hotfix. SonicWall published log-based IOCs. Watch for unexpected requests to /__api__/login and /wsproxy. That lets you tell whether you were breached before patching. Assume breach. Hunt first.
The two Microsoft zero-days matter for where they live. CVE-2026-56155 (AD FS) sits on the federated-identity layer. Treat active exploitation as a possible Golden SAML token-forgery event and review token-issuance logs for the prior two weeks after applying the KB. CVE-2026-56164 (SharePoint Server) is a network-reachable auth bypass. Hunt for webshells and anomalous file access. Both landed inside a record 622-CVE release. A working PoC, LegacyHive, for a User Profile Service EoP dropped within hours of the patch. The monthly-cadence assumption is dead.
| Threat | ID / Severity | Vector | Action |
|---|---|---|---|
| SonicWall SMA1000 | CVSS 10.0 | Unauth internet-facing SSRF | Hotfix now + hunt IOCs |
| Microsoft AD FS | CVE-2026-56155 | Federated identity, exploited | Patch + Golden SAML hunt |
| Microsoft SharePoint | CVE-2026-56164 | Network auth bypass, exploited | Patch + webshell hunt |
| ServiceNow | CVE-2026-6875 | Pre-auth RCE, Rhino escape | Verify fix + retro-hunt |
ServiceNow rounds out the fires. CVE-2026-6875 abuses GlideRecord query filters to escape the Rhino sandbox and run unsandboxed code. Mitigated within 24 hours. That stops future exploitation and nothing else. Confirm your instance received the Guarded Script and retro-hunt for prior pre-auth GlideRecord activity, new admin accounts, and commands on connected proxy servers.
Patch SonicWall first and the two exploited Microsoft zero-days next — the other 620 CVEs can wait for your KEV feed.
What to do
Patch or isolate every internet-facing SonicWall SMA1000 appliance immediately, then hunt logs for requests to /__api__/login and /wsproxy to confirm pre-patch compromise.
Fast-track CVE-2026-56155 (ADFS) and CVE-2026-56164 (SharePoint) ahead of the other 620 CVEs, and retro-hunt ADFS token-issuance logs for Golden SAML before declaring the patch sufficient.
Confirm your ServiceNow instance received the CVE-2026-6875 mitigation and hunt for anomalous pre-auth GlideRecord activity and new admin accounts.
