CVE-2022-22965: Spring Core Remote Code Execution Vulnerability Exploited In the Wild (SpringShell) (Updated)
Attackers actively exploit Spring Framework RCE CVE-2022-22965 (SpringShell, CVSS 9.8) to deploy webshells; patches 5.3.18/5.2.20 shipped March 31, 2022.
CVE-2022-22965 enables unauthenticated remote code execution in the widely used Spring Framework (CVSS 9.8), which Unit 42 has observed being exploited in the wild. The flaw stems from getCachedIntrospectionResults exposing the class object during parameter binding, letting attackers manipulate the class loader to modify Tomcat logging and upload a JSP webshell. Public PoCs require JDK 9+, Tomcat, WAR packaging, and spring-webmvc or spring-webflux dependencies on Spring 5.3.0-5.3.17, 5.2.0-5.2.19, or older. Fixes shipped in Spring Framework 5.3.18 and 5.2.20; the related Spring Cloud Function flaw CVE-2022-22963 was patched March 29, 2022.

One Exploit Chain, Two Espionage Campaigns: Chrome and Windows Under Fire
Two China-linked APT groups reused identical Chrome/Windows zero-day chain against NGOs, deploying GRIMWIDGE backdoor and LONGTALE credential-stealing extension.
Volexity reports that China-linked actors UTA0560 and JungleBamboo (APT31/TA412) ran byte-identical Chrome/Windows exploit chains against NGOs starting September 1, 2026, combining Chrome type confusion CVE-2026-85046, WebAssembly sandbox escape CVE-2026-87491, and Windows kernel flaw CVE-2026-85880. The Chrome bug was fixed in Chromium source but not yet shipped to Chrome users, making it an effective zero-day with an unusual patch gap. UTA0560 delivered the in-memory GRIMWEDGE JScript backdoor, while JungleBamboo deployed the SUPERSTOMP loader installing LONGTALE, a malicious Chrome extension disguised as Google Gemini that steals cookies, session tokens, and keystrokes. Volexity assesses with low confidence the exploit chain was sold or shared among different Chinese end-users.

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.

Cl0p Targets 40+ Organizations Through PTC Windchill Flaw
Cl0p claims over 40 organizations including Shell and Philips were breached by exploiting critical RCE CVE-2026-12569 in PTC Windchill and FlexPLM.
Cl0p claims more than 40 organizations were victimized via CVE-2026-12569 (CVSS 9.3), a critical deserialization-based remote code execution flaw in PTC Windchill PDMlink and FlexPLM, affecting releases prior to 11.0 M030; CISA added the flaw to its KEV catalog in June. ReliaQuest found the group deployed a custom web shell that maps vault data, decrypts all credentials in the Windchill keystore, and includes a Java class loader enabling arbitrary code execution, lateral movement, persistence, and large-scale data exfiltration without extra tooling. Named victims include Shell, Philips, Fiserv, Zebra Technologies, Ingersoll Rand, Toast, Mindray, and Apple lens supplier Largan Precision, with stolen data ranging from one gigabyte to multiple terabytes per target. The campaign mirrors Cl0p's earlier mass-exploitation extortion operations against MOVEit, Cleo, GoAnywhere, and Oracle E-Business Suite.
