Hackers Actively Exploit Critical WooCommerce Plugin Vulnerability to Upload PHP Backdoors
Attackers actively exploit CVE-2026-27540 (CVSS 9.8) in WooCommerce Wholesale Lead Capture plugin to upload PHP webshells; patch shipped in version 2.0.3.2.
CVE-2026-27540 (CVSS 9.8) in the WooCommerce Wholesale Lead Capture plugin affects versions 2.0.3.1 and earlier across roughly 6,000 active installations. The unauthenticated AJAX handler wwlc_file_upload_handler trusts a client-supplied file_settings allowlist, letting attackers upload shell.php for remote code execution. Wordfence has blocked more than 100,000 exploit attempts since disclosure, with spikes in June, July, and August 2026. The vendor fixed the flaw in version 2.0.3.2.

Cosmos EVM Flaw Exploited After Cosmos Labs Knew Every Blockchain Running It Was Vulnerable
Attackers exploited a critical Cosmos EVM balance bug (GHSA-7g4w-cg88-2cq2) to drain funds from six blockchains; fixed in v0.6.2 and v0.7.2.
Cosmos Labs disclosed that a critical balance-handling flaw in the shared Cosmos EVM module (GHSA-7g4w-cg88-2cq2, no CVE) was exploited to drain funds from six blockchains between August 20 and 25, 2026. The bug, reported April 25 and initially judged harmless, lets vesting accounts delegate more than their spendable balance, wrapping balances to roughly 2^256 and triggering unintended mint/burn in reconciliation, potentially halting chains or burning victims' holdings. Fixes shipped in v0.6.2 and v0.7.2 on August 19 as state-breaking coordinated network upgrades; operators who cannot upgrade must halt their chains. The post-mortem notes the team used public silent patching for a fund-threatening issue, contrary to its own bug bounty policy, and that eleven deployments had never registered with its security channels.

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.

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.

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.

Critical Cisco FMC Flaws Actively Exploited to Gain Root Access and Deploy Malware
Threat actors actively exploit Cisco FMC CVE-2026-20079 (CVSS 10.0) for root access, with clusters linked to Sandworm and Qilin ransomware.
Cisco Talos warns of active exploitation of CVE-2026-20079, a CVSS 10.0 authentication bypass in Cisco Secure Firewall Management Center allowing unauthenticated root-level code execution, and CVE-2026-20316 (CVSS 5.3), which permits login via a low-privileged static account for privilege escalation. Hotfixes are available now, with a broader hardening release planned for the week of September 14. Three post-compromise activity clusters were identified: UAT-12197 deployed a home.jsp web shell and cmd.jar command executor; UAT-11823, attributed with high confidence to a Sandworm-linked APT, deployed a Netcat reverse shell and Cyclops Blink; and UAT-11988 showed Qilin ransomware tactics including Active Directory enumeration and credential theft before deploying Qilin ransomware.

CVE-2026-16232: Check Point SmartConsole Auth Bypass
Check Point SmartConsole authentication bypass CVE-2026-16232 grants unauthenticated attackers full admin access; actively exploited and added to CISA KEV.
CVE-2026-16232 is an improper authentication flaw (CWE-287) in the Check Point SmartConsole login process that lets an unauthenticated remote attacker obtain an application token and authenticate with full administrative privileges. Exploitation requires the Management Server to be internet-reachable and the Trusted Clients list not restricted to specific administrator addresses. Check Point confirmed active exploitation affecting a small number of customers, and the vulnerability has been added to the CISA Known Exploited Vulnerabilities catalog. A hotfix is available via Check Point advisory sk185169.

SAP Commerce Cloud CVE-2026-58231 Targeted in Exploitation Attempts Days After Patch
A maximum-severity (CVSS 10.0) unauthenticated RCE flaw in SAP Commerce Cloud, CVE-2026-58231, is under active exploitation days after patching.
CVE-2026-58231, rated 10.0 on CVSS, stems from insufficient authorization checks and input validation in SAP Commerce Cloud, enabling unauthenticated arbitrary code execution. Defused Cyber's honeypots detected exploitation attempts three days after the patch, and KEVIntel independently confirmed two attempts on August 14 from a US IP address. Onapsis urges customers to patch and rebuild, with an IP Filter Set offered as a temporary workaround. No actor attribution yet, though prior SAP NetWeaver flaw CVE-2025-31324 was exploited by China-nexus and criminal groups.
