Cybersecurity researchers have disclosed details of yet another maximum-severity security flaw in n8n , a popular workflow automation platform, that allows an unauthenticated remote attacker to gain complete control over susceptible instances. The vulnerability, tracked as CVE-2026-21858 (CVSS score: 10.0), has been codenamed Ni8mare by Cyera Research Labs. Security researcher Dor Attias has been acknowledged for discovering and reporting the flaw on November 9, 2025. "A vulnerability in n8n allows an attacker to access files on the underlying server through execution of certain form-based workflows," n8n said in an advisory published today. "A vulnerable workflow could grant access to an unauthenticated remote attacker. This could result in exposure of sensitive information stored on the system and may enable further compromise depending on deployment configuration and workflow usage." With the latest development, n8n has disclosed four critical vulnerabili...

Popular artificial intelligence (AI)-powered Microsoft Visual Studio Code (VS Code) forks such as Cursor, Windsurf, Google Antigravity, and Trae have been found to recommend extensions that are non-existent in the Open VSX registry, potentially opening the door to supply chain risks when bad actors publish malicious packages under those names. The problem, according to Koi , is that these integrated development environments (IDEs) inherit the list of officially recommended extensions from Microsoft's extensions marketplace. These extensions don't exist in Open VSX. The VS Code extension recommendations can take two different forms: file-based, which are displayed as toast notifications when users open a file in specific formats, or software-based, which are suggested when certain programs are already installed on the host. "The problem: these recommended extensions didn't exist on Open VSX," Koi security researcher Oren Yomtov said. "The namespaces were u...

A new critical security vulnerability has been disclosed in n8n, an open-source workflow automation platform, that could enable an authenticated attacker to execute arbitrary system commands on the underlying host. The vulnerability, tracked as CVE-2025-68668 , is rated 9.9 on the CVSS scoring system. It has been described as a case of a protection mechanism failure. Cyera Research Labs' Vladimir Tokarev and Ofek Itach have been credited with discovering and reporting the flaw, which has been codenamed N8scape . It affects n8n versions from 1.0.0 up to, but not including, 2.0.0, and allows an authenticated user with permission to create or modify workflows to execute arbitrary operating system commands on the host running n8n. The issue has been addressed in version 2.0.0. "A sandbox bypass vulnerability exists in the Python Code Node that uses Pyodide," an advisory for the flaw states . "An authenticated user with permission to create or modify workflows can exp...

Users of the " @adonisjs/bodyparser " npm package are being advised to update to the latest version following the disclosure of a critical security vulnerability that, if successfully exploited, could allow a remote attacker to write arbitrary files on the server. Tracked as CVE-2026-21440 (CVSS score: 9.2), the flaw has been described as a path traversal issue affecting the AdonisJS multipart file handling mechanism. "@adonisjs/bodyparser" is an npm package associated with AdonisJS, a Node.js framework for developing web apps and API servers with TypeScript. The library is used to process AdonisJS HTTP request body . "If a developer uses MultipartFile.move() without the second options argument or without explicitly sanitizing the filename, an attacker can supply a crafted filename value containing traversal sequences, writing to a destination path outside the intended upload directory," the project maintainers said in an advisory released last week. ...

Cybersecurity researchers have disclosed details of what appears to be a new strain of Shai Hulud on the npm registry with slight modifications from the previous wave observed last month. The npm package that embeds the novel Shai Hulud strain is " @vietmoney/react-big-calendar ," which was uploaded to npm back in March 2021 by a user named "hoquocdat." It was updated for the first time on December 28, 2025, to version 0.26.2. The package has been downloaded 698 times since its initial publication. The latest version has been downloaded 197 times. Aikido, which spotted the package, said it has not spotted any major spread or infections following the release of the package. "This suggests we may have caught the attackers testing their payload," security researcher Charlie Eriksen said . "The differences in the code suggests that this was obfuscated again from the original source, not modified in place. This makes it highly unlikely to be a copy-ca...

A recently disclosed security vulnerability in MongoDB has come under active exploitation in the wild, with over 87,000 potentially susceptible instances identified across the world. The vulnerability in question is CVE-2025-14847 (CVSS score: 8.7), which allows an unauthenticated attacker to remotely leak sensitive data from the MongoDB server memory. It has been codenamed MongoBleed . "A flaw in zlib compression allows attackers to trigger information leakage," OX Security said . "By sending malformed network packets, an attacker can extract fragments of private data." The problem is rooted in MongoDB Server's zlib message decompression implementation ("message_compressor_zlib.cpp"). It affects instances with zlib compression enabled, which is the default configuration. Successful exploitation of the shortcoming could allow an attacker to extract sensitive information from MongoDB servers, including user information, passwords, and API keys. ...

Cybersecurity researchers have disclosed details of what has been described as a "sustained and targeted" spear-phishing campaign that has published over two dozen packages to the npm registry to facilitate credential theft. The activity, which involved uploading 27 npm packages from six different npm aliases, has primarily targeted sales and commercial personnel at critical infrastructure-adjacent organizations in the U.S. and Allied nations, according to Socket. "A five-month operation turned 27 npm packages into durable hosting for browser-run lures that mimic document-sharing portals and Microsoft sign-in, targeting 25 organizations across manufacturing, industrial automation, plastics, and healthcare for credential theft," researchers Nicholas Anderson and Kirill Boychenko said .

A critical security flaw has been disclosed in LangChain Core that could be exploited by an attacker to steal sensitive secrets and even influence large language model (LLM) responses through prompt injection. LangChain Core (i.e., langchain-core ) is a core Python package that's part of the LangChain ecosystem, providing the core interfaces and model-agnostic abstractions for building applications powered by LLMs. The vulnerability, tracked as CVE-2025-68664, carries a CVSS score of 9.3 out of 10.0. Security researcher Yarden Porat has been credited with reporting the vulnerability on December 4, 2025. It has been codenamed LangGrinch . "A serialization injection vulnerability exists in LangChain's dumps() and dumpd() functions," the project maintainers said in an advisory. "The functions do not escape dictionaries with 'lc' keys when serializing free-form dictionaries." "The 'lc' key is used internally by LangChain to mark ser...

A critical security vulnerability has been disclosed in the n8n workflow automation platform that, if successfully exploited, could result in arbitrary code execution under certain circumstances. The vulnerability, tracked as CVE-2025-68613 , carries a CVSS score of 9.9 out of a maximum of 10.0. Security researcher Fatih Çelik has been credited with discovering and reporting the flaw. The package has about 57,000 weekly downloads, according to statistics on npm. "Under certain conditions, expressions supplied by authenticated users during workflow configuration may be evaluated in an execution context that is not sufficiently isolated from the underlying runtime," the maintainers of the npm package said . "An authenticated attacker could abuse this behavior to execute arbitrary code with the privileges of the n8n process. Successful exploitation may lead to full compromise of the affected instance, including unauthorized access to sensitive data, modification of w...

Cybersecurity researchers have disclosed details of a new malicious package on the npm repository that works as a fully functional WhatsApp API, but also contains the ability to intercept every message and link the attacker's device to a victim's WhatsApp account. The package, named " lotusbail ," has been downloaded over 56,000 times since it was first uploaded to the registry by a user named "seiren_primrose" in May 2025. Of these, 711 downloads took place over the last week. The library is still available for download as of writing. Under the cover of a functional tool, the malware "steals your WhatsApp credentials, intercepts every message, harvests your contacts, installs a persistent backdoor, and encrypts everything before sending it to the threat actor's server," Koi Security researcher Tuval Admoni said in a report published over the weekend. Specifically, it's equipped to capture authentication tokens and session keys, messa...

Cybersecurity researchers have discovered a new malicious NuGet package that typosquats and impersonates the popular .NET tracing library and its author to sneak in a cryptocurrency wallet stealer. The malicious package, named " Tracer.Fody.NLog ," remained on the repository for nearly six years. It was published by a user named "csnemess" on February 26, 2020. It masquerades as " Tracer.Fody ," which is maintained by " csnemes ." The package continues to remain available as of writing, and has been downloaded at least 2,000 times, out of which 19 took place over the last six weeks for version 3.2.4.  "It presents itself as a standard .NET tracing integration but in reality functions as a cryptocurrency wallet stealer," Socket security researcher Kirill Boychenko said . "Inside the malicious package, the embedded Tracer.Fody.dll scans the default Stratis wallet directory, reads *.wallet.json files, extracts wallet data, and exf...

Multiple security vulnerabilities have been disclosed in the open-source private branch exchange (PBX) platform FreePBX, including a critical flaw that could result in an authentication bypass under certain configurations. The shortcomings, discovered by Horizon3.ai and reported to the project maintainers on September 15, 2025, are listed below - CVE-2025-61675 (CVSS score: 8.6) - Numerous authenticated SQL injection vulnerabilities impacting four unique endpoints (basestation, model, firmware, and custom extension) and 11 affected parameters that enable read and write access to the underlying SQL database CVE-2025-61678 (CVSS score: 8.6) - An authenticated arbitrary file upload vulnerability that allows an attacker to exploit the firmware upload endpoint to upload a PHP web shell after obtaining a valid PHPSESSID and run arbitrary commands to leak the contents of sensitive files (e.g., "/etc/passwd") CVE-2025-66039 (CVSS score: 9.3) - An authentication bypass vulne...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added a high-severity security flaw impacting OSGeo GeoServer to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation in the wild.

The following...

Cybersecurity researchers have discovered two new extensions on Microsoft Visual Studio Code (VS Code) Marketplace that are designed to infect developer machines with stealer malware. The VS Code extensions masquerade as a premium dark theme and an artificial intelligence (AI)-powered coding assistant, but, in actuality, harbor covert functionality to download additional payloads, take screenshots, and siphon data. The captured information is then sent to an attacker-controlled server. "Your code. Your emails. Your Slack DMs. Whatever's on your screen, they're seeing it too," Koi Security's Idan Dardikman said . "And that's just the start. It also steals your WiFi passwords, reads your clipboard, and hijacks your browser sessions." The names of the extensions are below - BigBlack.bitcoin-black (16 installs) - Removed by Microsoft on December 5, 2025  BigBlack.codo-ai (25 installs) - Removed by Microsoft on December 8, 2025 Microsoft's l...

A critical security flaw has been disclosed in Apache Tika that could result in an XML external entity ( XXE ) injection attack. The vulnerability, tracked as CVE-2025-66516 , is rated 10.0 on the CVSS scoring scale, indicating maximum severity. "Critical XXE in Apache Tika tika-core (1.13-3.2.1), tika-pdf-module (2.0.0-3.2.1) and tika-parsers (1.13-1.28.5) modules on all platforms allows an attacker to carry out XML External Entity injection via a crafted XFA file inside of a PDF," according to an advisory for the vulnerability.

This, in tur...

A maximum-severity security flaw has been disclosed in React Server Components (RSC) that, if successfully exploited, could result in remote code execution. The vulnerability, tracked as CVE-2025-55182, carries a CVSS score of 10.0. The vulnerability has been codenamed React2shell . It allows "unauthenticated remote code execution by exploiting a flaw in how React decodes payloads sent to React Server Function endpoints," the React Team said in an alert issued today. "Even if your app does not implement any React Server Function endpoints, it may still be vulnerable if your app supports React Server Components." According to cloud security firm Wiz , the issue is a case of logical deserialization that stems from processing RSC payloads in an unsafe manner. As a result, an unauthenticated attacker could craft a malicious HTTP request to any Server Function endpoint that, when deserialized by React, achieves execution of arbitrary JavaScript code on the server. ...

Three critical security flaws have been disclosed in an open-source utility called Picklescan that could allow malicious actors to execute arbitrary code by loading untrusted PyTorch models, effectively bypassing the tool's protections. Picklescan , developed and maintained by Matthieu Maitre (@mmaitre314), is a security scanner that's designed to parse Python pickle files and detect suspicious imports or function calls, before they are executed. Pickle is a widely used serialization format in machine learning, including PyTorch , which uses the format to save and load models. But pickle files can also be a huge security risk , as they can be used to automatically trigger the execution of arbitrary Python code when they are loaded. This necessitates that users and organizations load trusted models, or load model weights from TensorFlow and Flax. The issues discovered by JFrog essentially make it possible to bypass the scanner, present the scanned model files as safe, and e...

Cybersecurity researchers have discovered vulnerable code in legacy Python packages that could potentially pave the way for a supply chain compromise on the Python Package Index (PyPI) via a domain takeover attack. Software supply chain security company ReversingLabs said it found the "vulnerability" in bootstrap files provided by a build and deployment automation tool named "zc.buildout." "The scripts automate the process of downloading, building, and installing the required libraries and tools," security researcher Vladimir Pezo said . "Specifically, when the bootstrap script is executed, it fetches and executes an installation script for the package Distribute from python-distribute[.]org – a legacy domain that is now available for sale in the premium price range while being managed to drive ad revenue." The PyPI packages that include a bootstrap script that accesses the domain in question include tornado, pypiserver, slapos.core, roman, x...

The second wave of the Shai-Hulud supply chain attack has spilled over to the Maven ecosystem after compromising more than 830 packages in the npm registry. The Socket Research Team said it identified a Maven Central package named org.mvnpm:posthog-node:4.18.1 that embeds the same two components associated with Sha1-Hulud: the "setup_bun.js" loader and the main payload "bun_environment.js." The company told The Hacker News that org.mvnpm:posthog-node:4.18.1 was the only Java package identified so far. "This means the PostHog project has compromised releases in both the JavaScript/npm and Java/Maven ecosystems, driven by the same Shai Hulud v2 payload," the cybersecurity company said in a Tuesday update. It's worth noting that the Maven Central package is not published by PostHog itself. Rather, the "org.mvnpm" coordinates are generated via an automated mvnpm process that rebuilds npm packages as Maven artifacts. The Maven Central said...

Cybersecurity researchers have uncovered critical remote code execution vulnerabilities impacting major artificial intelligence (AI) inference engines, including those from Meta, Nvidia, Microsoft, and open-source PyTorch projects such as vLLM and SGLang. "These vulnerabilities all traced back to the same root cause: the overlooked unsafe use of ZeroMQ (ZMQ) and Python's pickle deserialization," Oligo Security researcher Avi Lumelsky said in a report published Thursday. At its core, the issue stems from what has been described as a pattern called ShadowMQ , in which the insecure deserialization logic has propagated to several projects as a result of code reuse. The root cause is a vulnerability in Meta's Llama large language model (LLM) framework ( CVE-2024-50050 , CVSS score: 6.3/9.3) that was patched by the company last October. Specifically, it involved the use of ZeroMQ's recv_pyobj() method to deserialize incoming data using Python's pickle module. ...
