Day 4

FortiMail zero-day lands in KEV as attacks intensify

Why it matters: A CVSS 9.8 flaw in an email security product is being exploited now and the only defense until patches land is the workaround, so teams need to apply it and hunt for compromise in the meantime.

Zimbra WSO2 and Cisco flaws pile onto urgent patch queues

Why it matters: Zimbra, WSO2 API Manager and Cisco SD-WAN Manager are all externally exposed and all carry KEV or CISA urgency, so remediation for them competes for the same short window, and WSO2 has reportedly been exploited since September 13, so exposure may already predate patching.

What moved

Three more internet-facing products hit the urgent queue: Zimbra Collaboration, WSO2 API Manager and Cisco SD-WAN Manager, all with CISA urgency attached. The FortiMail zero-day (CVE-2026-104286) stays live, with a workaround available while Fortinet's patches are still pending.

Where the discourse splits

No real disagreement in today's sources.

Worth watching

Whether Fortinet ships patches for the FortiMail flaw CVE-2026-104286, since only a workaround exists so far
Whether Zimbra Collaboration admins have moved to ZCS 10.1.20 where zimbra-snmp is in play
Cisco SD-WAN Manager exposure for CVE-2026-76504, which has no workaround and a CISA deadline of October 3, 2026

Only a few sources in this niche clear the publication-authority bar right now, so this slate is short. The rest were low-authority (SEO/aggregator/free-host) and weren't cited. Widen the window (try 'this month') or loosen source_quality to surface more.
