🔒 Datadog Security Labs disclosed an active web-traffic hijacking campaign that leverages the critical React2Shell vulnerability (CVE-2025-55182, CVSS 10.0) to inject malicious nginx configurations. Attackers use multi-stage shell scripts to create proxy_pass rules that route requests to attacker-controlled backends, focusing on Asian and government/education TLDs and Baota management panels. GreyNoise telemetry links the activity to two dominant IPs and over 1,000 unique sources.

⚠️ Researchers at Datadog Security Labs report threat actors are exploiting the React2Shell vulnerability (CVE-2025-55182) in React 19 to execute code on servers and then target NGINX instances managed with Boato Panel, focusing on several Asian TLDs and Chinese hosting. Attackers use automated, multi-stage toolkits to discover targets, persist, and write malicious NGINX configs that redirect traffic for cryptomining, credential phishing, or malware delivery. Defenses include prompt patching, locking down configuration files, maintaining configuration records, and monitoring NGINX advisories.

⚠️ Researchers at Datadog Security Labs report that threat actors are exploiting the React2Shell vulnerability to compromise servers running NGINX managed via Boato Panel and to hijack web traffic. Attackers deploy multi-stage scripts that discover targets, establish persistence, and generate malicious configuration files to redirect users or deliver malware. The campaign targets primarily Asian domains and Chinese hosting infrastructure, and unpatched React server components remain at high risk.

🔒 Multiple critical vulnerabilities in the open-source workflow platform n8n (tracked as CVE-2026-25049) allow any authenticated user who can create or edit workflows to escape sandboxing and execute arbitrary code on the host server. Independent researchers at Pillar Security, Endor Labs and SecureLayer7 identified sanitization and AST-sandboxing bypasses — including a type-confusion issue and Function-constructor exploits — enabling access to Node.js globals, the filesystem, credentials and connected cloud accounts. n8n released fixes (notably 2.4.0, later 2.5.2 and 1.123.17) and recommends immediate patching, rotating the N8N_ENCRYPTION_KEY and stored credentials, and limiting workflow creation until environments are hardened.

🛡️ Researchers disclosed a critical prompt-injection flaw, codenamed DockerDash, that allowed malicious Docker image metadata to hijack the Ask Gordon AI assistant in Docker Desktop and the Docker CLI. The vulnerability, discovered by Noma Labs, could enable remote code execution or sensitive data exfiltration by treating unverified LABEL fields as executable instructions. Docker fixed the issue in Ask Gordon version 4.50.0 (November 2025). Administrators should upgrade and apply zero-trust validation to AI toolchains and MCP/Gateway integrations.

⚠️ Noma Labs disclosed a critical vulnerability, dubbed DockerDash, in Docker's Ask Gordon AI assistant that allows unverified image metadata to be treated as executable instructions. The flaw exploits a trust failure in the Model Context Protocol (MCP) gateway: Ask Gordon reads Docker LABEL metadata, forwards the interpreted content to MCP, and MCP tools execute it without validation. Depending on deployment this can enable remote code execution (cloud/CLI) or large-scale data exfiltration and reconnaissance in Docker Desktop. Docker issued mitigations in Docker Desktop 4.50.0 and users are urged to upgrade.

🔒 VulnCheck observed active exploitation of CVE-2025-11953 (Metro4Shell), a critical RCE in the @react-native-community/cli Metro Development Server first seen on December 21, 2025. With a CVSS score of 9.8, the flaw enables unauthenticated remote command execution and was weaponized to deliver a Base64-encoded PowerShell loader that adds Microsoft Defender exclusions. The loader opens a raw TCP channel to 8.218.43.248:60124 to fetch and execute a Rust-based binary with anti-analysis checks; VulnCheck links the activity to multiple attacker IPs and describes it as operational exploitation.

🚨 Researchers report attackers are exploiting CVE-2025-11953 in the React Native Metro server to deliver malicious, cross-platform payloads to developer machines. The vulnerability stems from the /open-url endpoint accepting POST data that is passed unsanitized to the system open() call, enabling command execution on Windows and arbitrary executable launches on Unix-like hosts. JFrog disclosed the flaw in early November and it was fixed in @react-native-community/cli-server-api 20.0.0 and later, but active exploitation tracked as 'Metro4Shell' has been observed delivering base64-encoded payloads for both Windows and Linux.

🔓 Security researchers warn that attackers are exploiting the critical CVE-2025-11953 flaw in the React Native Metro server to drop malicious Windows and Linux payloads. The issue abuses the development-only /open-url HTTP endpoint, which accepts POST requests and can pass a user-supplied URL unsanitized to the system open() call. JFrog disclosed the bug and it was fixed in @react-native-community/cli-server-api v20.0.0+, but active exploitation (Metro4Shell) has been observed delivering base64 PowerShell stagers and UPX-packed binaries.

🔎 The Russia-linked threat actor APT28 has been observed exploiting CVE-2026-21509 in targeted Microsoft Office document attacks as part of Operation Neusploit. Zscaler ThreatLabz reported activity beginning on January 29, 2026, using localized lures and server-side geofilters to deliver malicious DLLs only to intended victims in Ukraine, Slovakia, and Romania. The exploit chains employ RTF/Word files that drop two distinct loaders: a C++ email stealer named MiniDoor and a more elaborate PixyNetLoader, which uses steganography and COM hijacking to deploy a Covenant Grunt implant. The campaign demonstrates focused espionage objectives, targeted evasion, and persistent C2 capabilities.

🔒 A high-severity vulnerability (CVE-2026-25253, CVSS 8.8) in OpenClaw allowed a crafted link or webpage to exfiltrate a stored gateway token and enable one-click remote code execution.
