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...

Security teams are still catching malware. The problem is what they're not catching. More attacks today don't arrive as files. They don't drop binaries. They don't trigger classic alerts. Instead, they run quietly through tools that already exist inside the environment — scripts, remote access, browsers, and developer workflows. That shift is creating a blind spot. Join us for a deep-dive technical session with the Zscaler Internet Access team. They will reveal how to unmask "hidden-in-plain-sight" tactics, why traditional defenses fall short, and exactly what needs to change. Secure your spot for the live session ➜ In this session, experts will cover: "Living off the Land" Attacks: These use trusted system tools like PowerShell, WMI, or remote desktop. File-based detection often sees nothing wrong because, technically, nothing new was installed. Fileless "Last Mile" Reassembly Attacks: Obfuscated HTML and JavaScript can e...

Open-source workflow automation platform n8n has warned of a maximum-severity security flaw that, if successfully exploited, could result in authenticated remote code execution (RCE).

Users are advised to upgrade to this version or later to completely address the vuln...

Non-human employees are becoming the future of cybersecurity, and enterprises need to prepare accordingly. As organizations scale Artificial Intelligence (AI) and cloud automation, there is exponential growth in Non-Human Identities (NHIs), including bots, AI agents, service accounts and automation scripts. In fact, 51% of respondents in ConductorOne's 2025 Future of Identity Security Report said the security of NHIs is now just as important as that of human accounts. Yet, despite their presence in modern organizations, NHIs often operate outside the scope of traditional Identity and Access Management (IAM) systems. This growing dependence on non-human users creates new attack surfaces that organizations must urgently prepare for. Without full visibility and proper oversight, NHIs may have over-permissioned standing access and static credentials, making them valuable targets for cybercriminals. To secure NHIs with the same precision as human identities, organizations must develop mo...

Veeam has released security updates to address multiple flaws in its Backup & Replication software, including a "critical" issue that could result in remote code execution (RCE). The vulnerability, tracked as CVE-2025-59470, carries a CVSS score of 9.0. "This vulnerability allows a Backup or Tape Operator to perform remote code execution (RCE) as the postgres user by sending a malicious interval or order parameter," it said in a Tuesday bulletin. According to Veeam's documentation, a user with a Backup Operator role can start and stop existing jobs; export backups; copy backups; and create VeeamZip backups. A Tape Operator user, on the other hand, can run tape backup jobs or tape catalog jobs; eject tapes; import and export tapes; move tapes to a media pool; copy or erase tapes; and set a tape password. In other words, these roles are considered highly privileged, and organizations should already be taking adequate protections to prevent them from bei...

Threat actors engaging in phishing attacks are exploiting routing scenarios and misconfigured spoof protections to impersonate organizations' domains and distribute emails that appear as if they have been sent internally. "Threat actors have leveraged this vector to deliver a wide variety of phishing messages related to various phishing-as-a-service (PhaaS) platforms such as Tycoon 2FA ," the Microsoft Threat Intelligence team said in a Tuesday report. "These include messages with lures themed around voicemails, shared documents, communications from human resources (HR) departments, password resets or expirations, and others, leading to credential phishing." While the attack vector is not necessarily new , the tech giant said it has witnessed a surge in the use of the tactic since May 2025 as part of opportunistic campaigns targeting a wide variety of organizations across multiple industries and verticals. This includes a campaign that has employed spoofed e...

A newly discovered critical security flaw in legacy D-Link DSL gateway routers has come under active exploitation in the wild. The vulnerability, tracked as CVE-2026-0625 (CVSS score: 9.3), concerns a case of command injection in the "dnscfg.cgi" endpoint that arises as a result of improper sanitization of user-supplied DNS configuration parameters. "An unauthenticated remote attacker can inject and execute arbitrary shell commands, resulting in remote code execution," VulnCheck noted in an advisory. "The affected endpoint is also associated with unauthenticated DNS modification ('DNSChanger') behavior documented by D-Link , which reported active exploitation campaigns targeting firmware variants of the DSL-2740R, DSL-2640B, DSL-2780B, and DSL-526B models from 2016 through 2019." The cybersecurity company also noted that exploitation attempts targeting CVE-2026-0625 were recorded by the Shadowserver Foundation on November 27, 2025. Some of ...

Cybersecurity researchers have discovered two new malicious extensions on the Chrome Web Store that are designed to exfiltrate OpenAI ChatGPT and DeepSeek conversations alongside browsing data to servers under the attackers' control. The names of the extensions, which collectively have over 900,000 users, are below - Chat GPT for Chrome with GPT-5, Claude Sonnet & DeepSeek AI (ID: fnmihdojmnkclgjpcoonokmkhjpjechg, 600,000 users) AI Sidebar with Deepseek, ChatGPT, Claude, and more. (ID: inhcgfpbfdjbjogdfjbclgolkmhnooop, 300,000 users) The findings come weeks after Urban VPN Proxy , another extension with millions of installations on Google Chrome and Microsoft Edge, was caught spying on users' chats with artificial intelligence (AI) chatbots. This tactic of using browser extensions to stealthily capture AI conversations has been codenamed Prompt Poaching by Secure Annex. The two newly identified extensions "were found exfiltrating user conversations and all ...

The CERT Coordination Center (CERT/CC) has disclosed details of an unpatched security flaw impacting TOTOLINK EX200 wireless range extender that could allow a remote authenticated attacker to gain full control of the device. The flaw, CVE-2025-65606 (CVSS score: N/A), has been characterized as a flaw in the firmware-upload error-handling logic, which could cause the device to inadvertently start an unauthenticated root-level telnet service. CERT/CC credited Leandro Kogan for discovering and reporting the issue.  "An authenticated attacker can trigger an error condition in the firmware-upload handler that causes the device to start an unauthenticated root telnet service, granting full system access," CERT/CC said . Successful exploitation of the flaw requires an attacker to be already authenticated to the web management interface to access the firmware-upload functionality. CERT/CC said the firmware-upload handler enters an "abnormal error state" when certain ...

Source: Securonix Cybersecurity researchers have disclosed details of a new campaign dubbed PHALT#BLYX that has leveraged ClickFix -style lures to display fixes for fake blue screen of death ( BSoD ) errors in attacks targeting the European hospitality sector. The end goal of the multi-stage campaign is to deliver a remote access trojan known as DCRat , according to cybersecurity company Securonix. The activity was detected in late December 2025. "For initial access, the threat actors utilize a fake Booking.com reservation cancellation lure to trick victims into executing malicious PowerShell commands, which silently fetch and execute remote code," researchers Shikha Sangwan, Akshay Gaikwad, and Aaron Beardslee said . The starting point of the attack chain is a phishing email impersonating Booking.com that contains a link to a fake website (e.g., "low-house[.]com"). The messages warn recipients of unexpected reservation cancellations, urging them to click the ...

The Invisible Half of the Identity Universe Identity used to live in one place - an LDAP directory, an HR system, a single IAM portal. Not anymore. Today, identity is fragmented across SaaS, on-prem, IaaS, PaaS, home-grown, and shadow applications. Each of these environments carries its own accounts, permissions, and authentication flows. Traditional IAM and IGA tools govern only the nearly managed half of this universe - the users and apps that have been fully onboarded, integrated, and mapped. Everything else remains invisible: the unverified, non-human, unprotected mass of identities we call identity dark matter. Every new or modernized app demands onboarding - connectors, schema mapping, entitlement catalogs, and role modeling - work that consumes time, money, and expertise. Many applications never make it that far. The result is fragmentation: unmanaged identities and permissions operating outside corporate governance. And beyond the human layer lies an even larger challenge...

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.
