Cisco email security boxes can be rooted by... an email

Attackers actively exploit critical Cisco Secure Email Gateway flaw CVE-2026-76461, turning a malicious email into unauthenticated root access.

Cisco Secure Email Gateway appliances are being actively exploited via CVE-2026-76461, a CVSS 9.8 AsyncOS flaw requiring no authentication—a crafted email can yield root command execution with no workarounds. Cisco's PSIRT became aware of active exploitation in September; some Secure Email Cloud customers showed indicators of compromise and all cloud devices were upgraded to AsyncOS 16.5.0-780. The bug is in CISA's KEV catalog with federal agencies ordered to remediate by September 17; Shadowserver counted 400+ exposed appliances. Fixes are available in AsyncOS 15.5.5-014, 16.0.4-302, and 16.5.0-780, and attackers with root may tamper with logs to hide activity.

Hackers Actively Exploiting Gitea n-day RCE Vulnerability in the Wild to Hijack Instances

Chinese-speaking Red Heron actors mass-exploit Gitea n-day RCE CVE-2026-60004 to steal source code, credentials, and pivot into victim networks.

Acronis Threat Research Unit reports active in-the-wild exploitation of Gitea RCE CVE-2026-60004 (CVSS 9.8, versions 1.17-1.27.0, fixed in 1.27.1) by a Chinese-speaking actor dubbed Red Heron. The actor scanned 1,386 Gitea servers across seven countries, held a separate list of 477 Taiwan-based targets, and confirmed victims in Canada, Argentina, Taiwan, the US, and Sri Lanka. Intrusions deployed the JITTERLY Linux implant with the SIXZUT LD_PRELOAD rootkit, stole password hashes and SSH keys, and in one case gained root admin access to a three-node Proxmox cluster.
