CISA: Critical VMware RCE flaw now exploited by ransomware gangs

CISA warns ransomware gangs now exploit critical VMware vCenter syslog RCE CVE-2026-59310, already KEV-listed after APT compromises across 47 countries.

Broadcom patched critical directory traversal flaw CVE-2026-59310 in the vCenter Syslog server on July 29, warning of unauthenticated remote code execution. QUIRSO subsequently found 361 compromised IPs across 47 countries after a suspected APT deployed a reverse SSH tool for persistence and remote access. CISA added the flaw to its KEV catalog with a three-day patch deadline for federal agencies, and over the weekend updated it to flag active abuse by ransomware gangs. Shadowserver tracks over 450 exposed vCenter servers, and CISA has tagged 26 VMware vulnerabilities as exploited in the wild over five years, nine abused by ransomware.

Hackers target exposed Vite dev servers to steal AWS, Azure secrets

Mass scanning campaign exploits CVE-2026-39364 in exposed Vite dev servers to steal AWS, Azure, and Terraform credentials.

F5 honeypots detected over 800 attacks and roughly 32,000 events in a month against internet-exposed Vite development servers, abusing CVE-2026-39364 (file access control bypass in Vite 7.1.0-7.3.2 and 8.x before 8.0.5) via parameters like ?raw and ?import&raw. Attackers used extensive wordlists to harvest .env files, AWS/Azure credentials, Terraform state, and /proc/self/environ, with double-encoded traversal to bypass WAFs. The same IPs also leveraged older Vite flaws CVE-2025-30208, actively-exploited CVE-2025-31125, and CVE-2024-45811, primarily from US, Belgium, and Netherlands using Google Cloud ranges.

Cisco patches Secure Email Gateway zero-day exploited in attacks

Cisco patches actively exploited Secure Email Gateway zero-day CVE-2026-76461 enabling unauthenticated root command execution; CISA adds it to KEV.

Cisco disclosed that a critical zero-day (CVE-2026-76461) in the email parsing logic of AsyncOS for Secure Email Gateway is being actively exploited, allowing unauthenticated remote attackers to execute arbitrary SQL statements that lead to root-level command execution on virtual and physical appliances. CISA added the flaw to its KEV catalog and ordered federal agencies to patch within three days, by September 17. Cisco also patched four other critical SEG/SEWM vulnerabilities (CVE-2026-76440, CVE-2026-76441, CVE-2026-20353, CVE-2026-76443) with no evidence of exploitation, and shared IOCs including suspicious SQL statements in mail_logs.

CISA: Hackers now exploit max severity GitLab flaw in attacks

CISA added max-severity GitLab CVE-2026-85706 to its exploited-flaws catalog after watchTowr observed probing of unpatched servers.

CISA added CVE-2026-85706, a maximum-severity GitLab flaw caused by missing authentication enforcement and improper path confinement in the repository commits API, to its actively exploited vulnerabilities catalog. Unauthenticated attackers can read credentials, secrets, and arbitrary files from vulnerable servers via a single HTTP request. GitLab patched the issue in CE/EE versions 19.3.2, 19.2.6, and 19.1, and federal agencies have three days to remediate under BOD 26-04. watchTowr reported in-the-wild probes for unpatched GitLab servers, and this is the fourth GitLab vulnerability CISA has tagged as actively exploited since November 2021.

Hackers exploit Tencent app flaw to deploy GrayRabbit malware

UNC3569 actively exploits one-click RCE in Tencent Sogou Input Method to deploy the GrayRabbit backdoor, patched in version 16.3.0.3498.

Gen Digital reports that China-aligned UNC3569 is actively exploiting CVE-2026-51990, a one-click RCE chain in Tencent Sogou Input Method for Windows, which has hundreds of millions of installations in China. The chain abuses unvalidated command-line argument injection via the sgbiz: URI handler, unrestricted URL navigation in a CEF-based webview, and an unsandboxed outdated Chromium 80 engine to gain code execution and install the GrayRabbit backdoor. The analyzed malware is a mature 64-bit variant with RC4-encoded C2 config supporting reverse shells, file transfer, and reflective plugin loading. Tencent patched the argument validation in version 16.3.0.3498, but the browser engine remains outdated and unsandboxed.
