Cybersecurity researchers have disclosed a now-patched, high-severity security flaw in Cursor, a popular artificial intelligence (AI) code editor, that could result in remote code execution (RCE). The vulnerability, tracked as CVE-2025-54135 (CVSS score: 8.6), has been addressed in version 1.3 released on July 29, 2025. It has been codenamed CurXecute by Aim Labs, which previously disclosed EchoLeak . "Cursor runs with developer‑level privileges, and when paired with an MCP server that fetches untrusted external data, that data can redirect the agent's control flow and exploit those privileges," the Aim Labs Team said in a report shared with The Hacker News. "By feeding poisoned data to the agent via MCP, an attacker can gain full remote code execution under the user privileges, and achieve any number of things, including opportunities for ransomware, data theft, AI manipulation and hallucinations, etc." In other words, the remote code execution can trigg...

Three different ClickFix campaigns have been found to act as a delivery vector for the deployment of a macOS information stealer called MacSync . "Unlike traditional exploit-based attacks, this method relies entirely on user interaction – usually in the form of copying and executing commands – making it particularly effective against users who may not appreciate the implications of running unknown and obfuscated terminal commands," Sophos researchers Jagadeesh Chandraiah, Tonmoy Jitu, Dmitry Samosseiko, and Matt Wixey said . It's currently not known if the campaigns are the work of the same threat actor. The use of ClickFix lures to distribute the malware was also flagged by Jamf Threat Labs in December 2025. The details of the three campaigns are as follows - November 2025: A campaign that used OpenAI's ChatGPT Atlas web browser as bait, delivered via sponsored search results on Google, to direct users to a fake Google Sites URL with a download button that, whe...

Cybersecurity researchers have discovered a vulnerability in Google's agentic integrated development environment (IDE), Antigravity, that could be exploited to achieve code execution. The flaw, since patched, combines Antigravity's permitted file-creation capabilities with an insufficient input sanitization in Antigravity's native file-searching tool, find_by_name, to bypass the program's Strict Mode , a restrictive security configuration that limits network access, prevents out-of-workspace writes, and ensures all commands are being run within a sandbox context . "By injecting the -X (exec-batch) flag through the Pattern parameter [in the find_by_name tool], an attacker can force fd to execute arbitrary binaries against workspace files," Pillar Security researcher Dan Lisichkin said in an analysis. "Combined with Antigravity's ability to create files as a permitted action, this enables a full attack chain: stage a malicious script, then trigger ...

Cybersecurity researchers have disclosed details of a now-patched vulnerability in the popular figma-developer-mcp Model Context Protocol ( MCP ) server that could allow attackers to achieve code execution. The vulnerability, tracked as CVE-2025-53967 (CVSS score: 7.5), is a command injection bug stemming from the unsanitized use of user input, opening the door to a scenario where an attacker can send arbitrary system commands. "The server constructs and executes shell commands using unvalidated user input directly within command-line strings. This introduces the possibility of shell metacharacter injection (|, >, &&, etc.)," according to a GitHub advisory for the flaw. "Successful exploitation can lead to remote code execution under the server process's privileges." Given that the Framelink Figma MCP server exposes various tools to perform operations in Figma using artificial intelligence (AI)-powered coding agents like Cursor, an attacker co...

A vulnerability in GitHub Codespaces could have been exploited by bad actors to seize control of repositories by injecting malicious Copilot instructions in a GitHub issue. The artificial intelligence (AI)-driven vulnerability has been codenamed RoguePilot by Orca Security. It has since been patched by Microsoft following responsible disclosure. "Attackers can craft hidden instructions inside a GitHub issue that are automatically processed by GitHub Copilot, giving them silent control of the in-codespaces AI agent," security researcher Roi Nisimi said in a report. The vulnerability has been described as a case of passive or indirect prompt injection where a malicious instruction is embedded within data or content that's processed by the large language model (LLM), causing it to produce unintended outputs or carry out arbitrary actions. The cloud security company also called it a type of AI-mediated supply chain attack that induces the LLM to automatically execute ...

OpenClaw has fixed a high-severity security issue that, if successfully exploited, could have allowed a malicious website to connect to a locally running artificial intelligence (AI) agent and take over control. "Our vulnerability lives in the core system itself – no plugins, no marketplace, no user-installed extensions – just the bare OpenClaw gateway, running exactly as documented," Oasis Security said in a report published this week. The flaw has been codenamed ClawJacked by the cybersecurity company. The attack assumes the following threat model: A developer has OpenClaw set up and running on their laptop, with its gateway , a local WebSocket server, bound to localhost and protected by a password. The attack kicks in when the developer lands on an attacker-controlled website through social engineering or some other means. The infection sequence then follows the steps below - Malicious JavaScript on the web page opens a WebSocket connection to localhost on the ...

A previously unknown vulnerability in OpenAI ChatGPT allowed sensitive conversation data to be exfiltrated without user knowledge or consent, according to new findings from Check Point. "A single malicious prompt could turn an otherwise ordinary conversation into a covert exfiltration channel, leaking user messages, uploaded files, and other sensitive content," the cybersecurity company said in a report published today. "A backdoored GPT could abuse the same weakness to obtain access to user data without the user's awareness or consent." Following responsible disclosure, OpenAI addressed the issue on February 20, 2026. There is no evidence that the issue was ever exploited in a malicious context. While ChatGPT is built with various guardrails to prevent unauthorized data sharing or generate direct outbound network requests , the newly discovered vulnerability bypasses these safeguards entirely by exploiting a side channel originating from the Linux runtime ...

A security weakness has been disclosed in the artificial intelligence (AI)-powered code editor Cursor that could trigger code execution when a maliciously crafted repository is opened using the program. The issue stems from the fact that an out-of-the-box security setting is disabled by default, opening the door for attackers to run arbitrary code on users' computers with their privileges. "Cursor ships with Workspace Trust disabled by default, so VS Code-style tasks configured with runOptions.runOn: 'folderOpen' auto-execute the moment a developer browses a project," Oasis Security said in an analysis. "A malicious .vscode/tasks.json turns a casual 'open folder' into silent code execution in the user's context." Cursor is an AI-powered fork of Visual Studio Code, which supports a feature called Workspace Trust to allow developers to safely browse and edit code regardless of where it came from or who wrote it. With this option disab...

Cybersecurity researchers have discovered a malicious npm package that masquerades as an OpenClaw installer to deploy a remote access trojan (RAT) and steal sensitive data from compromised hosts. The package, named " @openclaw-ai/openclawai ," was uploaded to the registry by a user named "openclaw-ai" on March 3, 2026. It has been downloaded 178 times to date. The library is still available for download as of writing. JFrog, which discovered the package, said it's designed to steal system credentials, browser data, crypto wallets, SSH keys, Apple Keychain databases, and iMessage history, as well as install a persistent RAT with remote access capabilities, SOCKS5 proxy, and live browser session cloning. It's tracking the activity under the name GhostClaw. "The attack is notable for its broad data collection, its use of social engineering to harvest the victim's system password, and the sophistication of its persistence and C2 [command-and-contro...

Cybersecurity researchers have discovered a set of 10 malicious npm packages that are designed to deliver an information stealer targeting Windows, Linux, and macOS systems. "The malware uses four layers of obfuscation to hide its payload, displays a fake CAPTCHA to appear legitimate, fingerprints victims by IP address, and downloads a 24MB PyInstaller-packaged information stealer that harvests credentials from system keyrings, browsers, and authentication services across Windows, Linux, and macOS," Socket security researcher Kush Pandya said . The npm packages were uploaded to the registry on July 4, 2025, and accumulated over 9,900 downloads collectively - deezcord.js dezcord.js dizcordjs etherdjs ethesjs ethetsjs nodemonjs react-router-dom.js typescriptjs zustand.js The multi-stage credential theft operation manifested in the form of various typosquatted packages impersonating popular npm libraries such as TypeScript, discord.js, ethers.js, nodemon, react...

Two Google Chrome extensions have turned malicious after what appears to be a case of ownership transfer , offering attackers a way to push malware to downstream customers, inject arbitrary code, and harvest sensitive data. The extensions in question, both originally associated with a developer named "akshayanuonline@gmail.com" (BuildMelon), are listed below - QuickLens - Search Screen with Google Lens (ID: kdenlnncndfnhkognokgfpabgkgehodd) - 7,000 users ShotBird - Scrolling Screenshots, Tweet Images & Editor (ID: gengfhhkjekmlejbhmmopegofnoifnjp) - 800 users While QuickLens is no longer available for download from the Chrome Web Store, ShotBird remains accessible as of writing. ShotBird was originally launched in November 2024, with its developer, Akshay Anu S (@AkshayAnuOnline), claiming on X that the extension is suitable for "creating professional, studio-like visuals," and that all processing happens locally. According to research published by mo...

A Türkiye-affiliated threat actor exploited a zero-day security flaw in an Indian enterprise communication platform called Output Messenger as part of a cyber espionage attack campaign since April 2024. "These exploits have resulted in a collection of related user data from targets in Iraq," the Microsoft Threat Intelligence team said . "The targets of the attack are associated with the Kurdish military operating in Iraq, consistent with previously observed Marbled Dust targeting priorities." The activity has been attributed to a threat group it tracks as Marbled Dust (formerly Silicon), which is also known as Cosmic Wolf, Sea Turtle, Teal Kurma, and UNC1326. The hacking crew is believed to have been active since at least 2017, although it wasn't until two years later that Cisco Talos documented attacks targeting public and private entities in the Middle East and North Africa. Early last year, it was also identified as targeting telecommunication, media, in...

Cybersecurity researchers have disclosed a high-severity security flaw in the artificial intelligence (AI)-powered code editor Cursor that could result in remote code execution. The vulnerability, tracked as CVE-2025-54136 (CVSS score: 7.2), has been codenamed MCPoison by Check Point Research, owing to the fact that it exploits a quirk in the way the software handles modifications to Model Context Protocol (MCP) server configurations. "A vulnerability in Cursor AI allows an attacker to achieve remote and persistent code execution by modifying an already trusted MCP configuration file inside a shared GitHub repository or editing the file locally on the target's machine," Cursor said in an advisory released last week. "Once a collaborator accepts a harmless MCP, the attacker can silently swap it for a malicious command (e.g., calc.exe) without triggering any warning or re-prompt." MCP is an open-standard developed by Anthropic that allows large language mode...

In what's the latest instance of a software supply chain attack, unknown threat actors managed to compromise Toptal's GitHub organization account and leveraged that access to publish 10 malicious packages to the npm registry. The packages contained code to exfiltrate GitHub authentication tokens and destroy victim systems, Socket said in a report published last week. In addition, 73 repositories associated with the organization were made public. The list of affected packages is below - @toptal/picasso-tailwind @toptal/picasso-charts @toptal/picasso-shared @toptal/picasso-provider @toptal/picasso-select @toptal/picasso-quote @toptal/picasso-forms @xene/core @toptal/picasso-utils @toptal/picasso-typograph All the Node.js libraries were embedded with identical payloads in their package.json files, attracting a total of about 5,000 downloads before they were removed from the repository. The nefarious code has been found to specifically target the preinstall and p...

Cyber threats are no longer coming from just malware or exploits. They’re showing up inside the tools, platforms, and ecosystems organizations use every day. As companies connect AI, cloud apps, developer tools, and communication systems, attackers are following those same paths. A clear pattern this week: attackers are abusing trust. Trusted updates, trusted marketplaces, trusted apps, even trusted AI workflows. Instead of breaking security controls head-on, they’re slipping into places that already have access. This recap brings together those signals — showing how modern attacks are blending technology abuse, ecosystem manipulation, and large-scale targeting into a single, expanding threat surface. ⚡ Threat of the Week OpenClaw announces VirusTotal Partnership — OpenClaw has announced a partnership with Google's VirusTotal malware scanning platform to scan skills that are being uploaded to ClawHub as part of a defense-in-depth approach to improve the security of the agen...

Cybersecurity researchers have discovered a critical security vulnerability in artificial intelligence (AI) company Anthropic's Model Context Protocol ( MCP ) Inspector project that could result in remote code execution (RCE) and allow an attacker to gain complete access to the hosts. The vulnerability, tracked as CVE-2025-49596 , carries a CVSS score of 9.4 out of a maximum of 10.0. "This is one of the first critical RCEs in Anthropic's MCP ecosystem, exposing a new class of browser-based attacks against AI developer tools," Oligo Security's Avi Lumelsky said in a report published last week. "With code execution on a developer's machine, attackers can steal data, install backdoors, and move laterally across networks - highlighting serious risks for AI teams, open-source projects, and enterprise adopters relying on MCP." MCP, introduced by Anthropic in November 2024, is an open protocol that standardizes the way large language model (LLM) appli...

The threat actors behind the Rhadamanthys information stealer have added new advanced features to the malware, including using artificial intelligence (AI) for optical character recognition (OCR) as part of what's called "Seed Phrase Image Recognition." "This allows Rhadamanthys to extract cryptocurrency wallet seed phrases from images, making it a highly potent threat for anyone dealing in cryptocurrencies," Recorded Future's Insikt Group said in an analysis of version 0.7.0 of the malware. "The malware can recognize seed phrase images on the client side and send them back to the command-and-control (C2) server for further exploitation." First discovered in the wild in September 2022, Rhadamanthys has emerged as one of the most potent information stealers that are advertised under the malware-as-a-service (MaaS) model, alongside Lumma and others. The malware continues to have an active presence despite suffering bans from underground forum...

The maintainers of the nx build system have alerted users to a supply chain attack that allowed attackers to publish malicious versions of the popular npm package and other auxiliary plugins with data-gathering capabilities. "Malicious versions of the nx package, as well as some supporting plugin packages, were published to npm, containing code that scans the file system, collects credentials, and posts them to GitHub as a repo under the user's accounts," the maintainers said in an advisory published Wednesday. Nx is an open-source, technology-agnostic build platform that's designed to manage codebases. It's advertised as an "AI-first build platform that connects everything from your editor to CI [continuous integration]." The npm package has over 3.5 million weekly downloads. The list of affected packages and versions is below. These versions have since been removed from the npm registry. The compromise of the nx package took place on August 26, 20...

ThreatsDay Bulletin is back on The Hacker News, and this week feels off in a familiar way. Nothing loud, nothing breaking everything at once. Just a lot of small things that shouldn’t work anymore but still do. Some of it looks simple, almost sloppy, until you see how well it lands. Other bits feel a little too practical, like they’re already closer to real-world use than anyone wants to admit. And the background noise is getting louder again, the kind people usually ignore. A few stories are clever in a bad way. Others are just frustratingly avoidable. Overall, it feels like quiet pressure is building in places that matter. Skim it or read it properly, but don’t skip this one.
