CYBER THREAT INTELLIGENCE BRIEFING
Microsoft observed attackers compromising exposed LiteLLM, RAGFlow, and Kestra workloads to steal secrets, establish persistence, execute commands, access data, and deploy XMRig. ShinyHunters also reportedly exploited CVE-2026-35273 before Oracle's out-of-band alert, while active attacks compromised Gitea and Zimbra servers.
ShinyHunters reportedly used the CVSS 9.8, unauthenticated remote-code-execution flaw in Oracle PeopleSoft Enterprise PeopleTools as a zero-day, compromising more than 300 instances across over 100 organizations. Nissan confirmed a related breach, universities were disproportionately affected, and exploitation preceded Oracle's alert.
CISA added CVE-2026-60004 to KEV as attackers executed commands and deployed a miner-like payload on vulnerable Gitea servers; Gitea 1.27.1 fixes the flaw. Attackers exploiting CVE-2026-73570 compromised at least 274 internet-facing Zimbra servers. Tenable and SentinelOne found that their datasets converged on 79% of vendor attack surfaces, while complex high-priority flaws stayed unpatched 24 days longer on average.
Editorial: Recommended Actions
01
PRIORITY
Inventory Oracle PeopleSoft Enterprise PeopleTools 8.61 and 8.62 immediately, restrict exposure, and investigate affected systems for compromise tied to CVE-2026-35273. ShinyHunters reportedly exploited this CVSS 9.8 unauthenticated RCE as a zero-day, compromising more than 300 instances at over 100 organizations, including Nissan and universities.
02
PRIORITY
Upgrade every Gitea server running versions 1.17 through 1.27.0 to Gitea 1.27.1 and examine exposed hosts for unauthorized command execution or miner-like payloads. Attackers are actively exploiting critical RCE flaw CVE-2026-60004, and CISA has added it to the Known Exploited Vulnerabilities catalog.
03
PRIORITY
Upgrade Zimbra Collaboration Suite to 10.1.20 and prioritize internet-facing deployments with zimbra-snmp and SNMP notifications enabled. CVE-2026-73570 permits unauthenticated command injection and remote code execution under those configurations, and attackers have already compromised at least 274 exposed servers.
04
PRIORITY
Remove LiteLLM, RAGFlow, and Kestra management interfaces from unnecessary public exposure, restrict access, and monitor command execution and secret access. Microsoft observed attackers compromising exposed workloads to harvest secrets, establish persistence, access data, and deploy XMRig; the LiteLLM intrusion likely chained CVE-2026-42271 and CVE-2026-48710.
05
PRIORITY
Prioritize remediation and compromise review for Zimbra CVE-2025-66376 and exposed Outlook Web Access systems, especially in government, defense, nuclear, research, aerospace, finance, and telecommunications. Russian state-backed Laundry Bear actively used zero-click email exploits to steal messages, session tokens, and credentials; viewing a crafted email can trigger compromise without interaction.
