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.

Adobe Patches Magento Zero-Day Exploited to Deploy Rust Backdoor and PHP Web Shell

Adobe patches actively exploited Magento zero-day CVE-2026-75650 (CVSS 10.0), abused since Sept 4 to deploy a Rust backdoor and PHP web shells.

Adobe released an emergency hotfix (VULN-39341) for CVE-2026-75650 (CVSS 10.0), dubbed StyleSmuggler by Sansec, which abuses Magento's template system via PHP code injection to trigger unauthenticated remote code execution in Adobe Commerce and Magento Open Source. Exploitation began September 4, 2026, with attackers deploying a Rust-based Linux backdoor and a PHP dropper that writes a web shell; one managed server was compromised 50 minutes after the first report. Previdian honeypots recorded 12 exploitation attempts from two unique IPs in China and Romania since September 7, all unsuccessful.

Telerik UI Padding-Oracle Bug Chained to Unauthenticated RCE — Public Exploit Released

TantoSec published a working exploit chaining a Telerik UI padding oracle to unauthenticated RCE; Progress patched the flaws in July.

TantoSec's Marcio Almeida released a full exploit chain and tooling for the RadAsyncUpload control in Telerik UI for ASP.NET AJAX, turning a padding oracle (CVE-2026-13182) into unauthenticated RCE via an unguarded type-resolution flaw (CVE-2026-13181, CVSS 8.1). Exploitation requires a rendered RadAsyncUpload handler and an explicit non-default encryption key, and took roughly 127,000 oracle requests (about an hour) in lab testing. Versions 2010.1.309 through 2026.2.519 are affected; Progress fixed the chain in 2026.2.708 on July 8, 2026, and no in-the-wild exploitation has been confirmed. A separate RCE chain in RadPersistenceManager and RadDockLayout (CVE-2026-13185, -13186, -13190) was also patched but has no public exploit.
