Three Critical Vulnerabilities in Adobe Campaign Classic Allow Arbitrary Code Execution
Adobe has disclosed three critical vulnerabilities in Adobe Campaign Classic that could allow attackers to execute arbitrary code on affected systems.
The flaws impact both Windows and Linux versions. Adobe published a security advisory on August 25, 2026, detailing two OS command injection vulnerabilities tracked as CVE-2026-76197 and CVE-2026-76195, as well as one server-side request forgery (SSRF) vulnerability identified as CVE-2026-76193.
All three issues received the highest possible CVSSv3.1 base score of 10.0 and are rated Critical. Successful exploitation could lead to full compromise of the Campaign Classic instance.
Adobe has released patched version 7.4.4 build 9401 for both Windows and Linux. The update applies to on-premises deployments as well as the on-premises components used in hybrid environments.
No in-the-wild attacks have been observed at the time of disclosure. Nevertheless, Adobe assessed the exploitation risk as high and assigned the highest remediation priority of 1, advising organizations to apply the update within 72 hours.

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.
