CISA Warns of Critical ScreenConnect Vulnerability Actively Exploited in Attacks

CISA added actively exploited ConnectWise ScreenConnect flaw CVE-2026-84869 to the KEV catalog, setting a September 14 patch deadline.

CISA added CVE-2026-84869, a critical improper privilege management and missing authorization flaw (CWE-269, CWE-862) in ConnectWise ScreenConnect, to its Known Exploited Vulnerabilities Catalog on September 11, 2026, confirming active exploitation. The flaw lets attackers transfer files to a device and execute them during an active remote ScreenConnect session without authorization or host-user confirmation, enabling payload delivery, unauthorized tools, and persistence while blending into legitimate remote-management traffic. CISA set a September 14 remediation deadline under BOD 26-04 and flagged the vulnerability as requiring forensic triage. ConnectWise has published a security bulletin, and defenders are urged to review exposure, sessions, file-transfer records, and outbound connections.

Android 0-day Vulnerability on Google Pixel Devices Actively Exploited in Attacks

Google patched CVE-2026-58704, an actively exploited Android zero-day allowing proximal privilege escalation via the Pixel cellular modem, urging the 2026-09-05 patch.

Google confirmed CVE-2026-58704, a high-severity elevation-of-privilege flaw in the Pixel cellular modem, is being exploited in limited, targeted attacks and shipped emergency fixes in the September 2026 Pixel Update Bulletin. The low-complexity bug requires no user interaction and enables proximal/adjacent privilege escalation with no additional execution privileges, phrasing Google has historically used for spyware-vendor and state-aligned zero-days. The Pixel bulletin patches 110 flaws including 12 critical RCEs, while the broader September Android update addressed roughly 180 vulnerabilities, including Wi-Fi memory-corruption bug CVE-2026-28662.

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.

Apache Superset SQL Injection Flaw Gets Public PoC Exploit

A public Python proof-of-concept exploit was released for CVE-2026-23980, an authenticated error-based SQL injection flaw in Apache Superset before 6.0.0.

A public proof-of-concept exploit repository now targets CVE-2026-23980, an error-based SQL injection affecting Apache Superset versions from 0.0.0 up to but not including 6.0.0. An authenticated user with read access can inject SQL through the sqlExpression or where parameters, potentially reaching business, customer, and security data depending on database configuration and privileges. Apache disclosed the flaw in February and urges upgrading to Superset 6.0.0; compensating controls include least-privilege database accounts, network restrictions, and log monitoring.

Marimo RCE Flaw Lets Hackers Steal AWS Credentials and Pivot to Bastion Host in 8 Seconds

Attacker exploited unauthenticated marimo WebSocket RCE CVE-2026-39987 to steal AWS credentials and SSH into a bastion host in eight seconds.

Sysdig Threat Research Team documented a real intrusion exploiting CVE-2026-39987 in marimo (versions up to 0.20.4, fixed in 0.23.0), where the unauthenticated /terminal/ws WebSocket endpoint exposed an interactive shell. Within eight seconds the attacker pulled AWS credentials from Redis, extracted an SSH private key from AWS Secrets Manager via Boto3, and authenticated to a bastion host; over nine hours the operator ran 850+ commands using a staged custom Python toolkit. Blocked EC2 Instance Connect attempts (SendSSHPublicKey to placeholder instance i-0000000000000000) provide a high-confidence detection signal.

Linux Kernel ZcopyReaper Vulnerability Lets Local Attackers Gain Root Privileges

Linux kernel RDS zero-copy flaw CVE-2026-43502 (ZcopyReaper) lets unprivileged local users gain root; fix in 7.1-rc3, public PoC published.

CVE-2026-43502, dubbed ZcopyReaper, is a Linux kernel local privilege escalation flaw in the RDS zerocopy send path, present since kernel 4.17, allowing unprivileged local attackers to gain root. NebuSec researcher Yuan Tan demonstrated root escalation on openSUSE kernel 6.4.0-150600.23.100; the fix landed in commit 44b550d88b26 with Linux 7.1-rc3 the first patched mainline release. Exploitation requires CONFIG_RDS and CONFIG_RDS_TCP but not unprivileged user namespaces, and PoC exploit material is publicly released alongside more than 20 other exploitable 2026 kernel CVEs.

Mass Scanning Targets Exposed Vite Servers to Steal AWS Keys and Azure Tokens

Attackers mass-scanned exposed Vite dev servers exploiting CVE-2026-39364 to read .env files and steal AWS keys and Azure tokens, per F5 Labs honeynet data.

Honeynet telemetry recorded 807 session-grouped attacks and roughly 32,000 raw events in August 2026 against exposed Vite development servers. CVE-2026-39364 (CVSS 7.5) is an unauthenticated file-read flaw in Vite 7.1.0 through 7.3.2 and 8.0.5 that bypasses server.fs.deny via query parameters like ?raw and ?import&raw to return files in plaintext. Attackers also probed older Vite flaws CVE-2025-30208, CVE-2025-31125, and CVE-2024-45811, and used wordlists to locate .env files, AWS credential files, Azure token stores, and Terraform state across Linux, container, and web paths. Exposed secrets could enable lateral movement or full cloud account takeover.

Hackers Exploit FortiGate SSL-VPN Flaw to Breach Thai ISP and Deploy MeshCentral Backdoor

Threat actors exploited FortiOS SSL-VPN flaw CVE-2024-21762 to breach Thai ISP Triple T Broadband, gaining root-level persistence via MeshCentral agents.

Attackers exploited CVE-2024-21762, an out-of-bounds write enabling unauthenticated RCE in FortiOS SSL-VPN, against Triple T Broadband's FortiGate 60F at mail.3bb.co.th, launching a Node.js reverse shell via a ROP payload. Hunt.io uncovered the operation through an exposed staging directory at 92.63.180[.]133:8888 containing 298 files of exploits, credential-harvesting scripts, session cookies, and a device inventory. Post-compromise, the actors deployed MeshCentral agents (device group TH-3BB, C2 www.ayuthayatech.com) running as root, plus a hidden SUID backdoor at /usr/local/bin/.rc, and also targeted an internal Pentaho/Tomcat server with Ghostcat (CVE-2020-1938). A cleanup script removed logs, shell histories, and web shells while deliberately preserving the MeshCentral agent and SUID backdoor.

One Click on a Malicious Link Lets Hackers Backdoor Sogou Input Method Users

Actively exploited one-click flaw in Sogou Input Method (CVE-2026-51990) let UNC3569 deploy the GRAYRABBIT espionage backdoor on Windows.

Gen Digital researchers found three weaknesses in Sogou Input Method's sgbiz protocol handler that chain into a one-click RCE running with the signed-in user's permissions. UNC3569 used the chain in an active intrusion, leveraging an unsandboxed Chromium 80 embedded browser, the known V8 flaw CVE-2021-38003, and DLL sideloading via 7-Zip to deploy the GRAYRABBIT backdoor. Tencent fixed the issue in version 16.3.0.3498 within 12 days of disclosure; Sogou is used by hundreds of millions of people, mainly in China.
