Researchers Disclose Full Remote Vehicle Takeover Chain in Major Automaker Connected Platform
Security researchers Shubs and Sam Curry have published a detailed account of a multi-stage attack that grants complete remote control over any connected vehicle belonging to a major undisclosed automaker in Australia and other large markets.
The researchers began by downloading and decompiling the official Android application. Analysis of the resulting code revealed that nearly all client functionality communicated with subdomains under redacted-telematics.com.au. One of these subdomains, admintool.redacted-telematics.com.au, exposed a test harness administrative interface whose entire JavaScript bundle was served publicly.
Inspection of the bundle disclosed numerous API endpoints that required no authentication beyond hardcoded keys embedded in the client. These endpoints allowed user account lookup by email address, retrieval of subscriber GUIDs from VIN numbers, and extraction of personal data including email addresses registered with the ForgeRock identity platform.
Further reconnaissance located an exposed ForgeRock OpenIDM instance at openidm.redacted-identity.com.au. Although protected by a Web Application Firewall, the instance accepted path traversal sequences such as /static%2f..%2fopenidm/ that bypassed WAF rules while still being processed correctly by the OpenIDM servlet container.
Using credentials discovered in a third-party JavaScript bundle, the researchers obtained administrative JWT tokens. They could then issue PATCH requests to reset passwords on any user profile. A subsequent Resource Owner Password Credentials flow against login.redacted-identity.com.au produced valid id_tokens that were exchanged for mobile application access tokens, completely bypassing multi-factor authentication.
With a valid application token the researchers could invoke the /v1/remote/route/command endpoint on api.redacted-telematics.com.au and remotely unlock, lock, honk, or start the engine of any vehicle associated with the compromised account.
The full attack chain required only a license plate number, publicly available VIN lookup services, and the discovered identity system weaknesses. No physical access or specialized hardware was necessary.

Nightmare Eclipse Publishes SignDrop Zero-Day in Windows CLFS Driver
Security researcher Abdelhamid Naseri, known as Nightmare Eclipse, has disclosed a new zero-day vulnerability named SignDrop affecting the Common Log File System (CLFS) driver in Windows. The flaw allows attackers to bypass authentication protections introduced by Microsoft in October 2025 and escalate privileges on affected systems. SignDrop exploits the way CLFS handles .cnpf authentication file creation when a new log file is generated, enabling a privileged process to open the file later and create it with SYSTEM rights. The technique can also be abused against any antivirus or EDR engine to disable self-protection mechanisms by making file creation requests appear to originate from the legitimate security process itself. Nightmare Eclipse confirmed the issue works on Windows 11 26H2, Windows 11 26H2 Experimental, and Windows Server 2025 Experimental, impacting an estimated 80 percent of Windows installations. No workaround exists other than waiting for a Microsoft patch, as disabling CLFS protections would reintroduce memory corruption risks. The researcher previously released multiple other zero-days, including BigDiskBuster and RoguePlanet targeting Microsoft Defender.
Telegram Patches RCE Vulnerabilities in HTML Widgets After Researcher Demonstrates Calculator Exploit
Telegram introduced HTML widgets for bots in early November, allowing JavaScript execution inside messages via the QuickJS engine. Security researcher V12 quickly demonstrated remote code execution by launching the system calculator on Android. Pavel Durov responded that no vulnerability existed because the user had to first start the bot, yet server-side fixes were deployed anyway. Multiple use-after-free and use-after-return bugs were identified in QuickJS and QuickJS-ng, some discovered with AI assistance from Claude Fable 5.1 and Mythos 5.2. Telegram isolated the widget engine into a separate process on Android, added syscall filtering, and limited nested graphical effects to prevent crashes. Desktop clients received the fixes across versions 7.4.2 and 7.4.3, while widgets were temporarily restricted server-side. Users are advised to update to Android 13.2.2 or Desktop 7.4.3 and avoid unknown bots.
Telegram Patches Critical QuickJS Sandbox Escape Vulnerability in Android Update 13.2.2
Telegram has released version 13.2.2 for Android to address a high-severity vulnerability in its HTML widgets for bots. The flaw resided in the QuickJS JavaScript engine within Telegram's QuickJS-ng fork and allowed scripts in ordinary messages to break out of the sandbox and execute native code on the device. The root cause was improper handling of the await using construct inside non-async functions, which triggered a use-after-return condition by freeing local variable references while nested functions still accessed the stack. The vulnerable code entered the QuickJS-ng main branch on May 16 as part of explicit resource management support. Security researcher Andreas Rösler discovered the issue during an AI-assisted audit with Anthropic's Claude model that identified 27 findings total. The patch enforces a syntax error on the invalid construct and was merged on November 10, the same day the Android release became available. Although reported against Android 13.2.1, the bug affected every platform using the affected engine fork.
Node.js Patches 16 Vulnerabilities Exposing TLS Private Keys and Cross-Connection Data
The Node.js project has released fixes addressing 16 vulnerabilities, seven of which are rated high severity. The most critical issue, CVE-2026-123864, allows an unauthenticated client to read memory from other HTTPS connections, potentially exposing TLS private keys and requests belonging to other users. Three supported release lines were affected, and exploitation requires a specific application code pattern involving res.flushHeaders() and res.end() calls before the request body is fully received. Additional high-severity flaws include CVE-2026-123863, which crashes HTTP/2 servers, CVE-2026-123866 that leaks server memory chunks to clients, and CVE-2026-123865 that causes permanent memory and file descriptor leaks in HTTP/2 servers. Several other CVEs affect TLS renegotiation, SNI callbacks, and file streaming functions. The project states that end-of-life branches including 20.x and 25.x remain vulnerable with no patches available.
