Networking infrastructure leads Wednesday's disclosures, with two CVSS 10 flaws in Cisco Catalyst SD-WAN (CVE-2026-20127 and CVE-2026-20182) confirmed under active exploitation alongside the related SD-WAN Manager issue CVE-2026-20262. The set totals 28 vulnerabilities, including 2 rated critical (down 93% from 30) and 26 high-priority (down 58% from 62). The remaining critical entries affect web applications, namely CVE-2026-49774 (CVSS 9.9) in Filipe Nasc RD Station and CVE-2026-40750 (CVSS 9.9) in the themagnifico52 Kids Online Store. Active exploitation extends beyond Cisco to Ivanti Sentry (CVE-2026-10520), Oracle PeopleSoft PeopleTools (CVE-2026-35273), and the Joomla Content Editor (CVE-2026-48907), indicating attacker interest in both edge gateways and content-management plugins. No patches were available across the disclosed set at publication, so organizations should prioritize mitigation, access restriction, and monitoring while fixes are pending.
Immediate action: Prioritize Cisco Catalyst SD-WAN and SD-WAN Manager, Ivanti Sentry, and Oracle PeopleSoft PeopleTools, which face active exploitation at CVSS 9.5 and above. With no patches currently available, restrict management-interface access, apply vendor workarounds, and increase monitoring on affected systems until fixes ship.
