Open a repository in Cursor on Windows and, if a file named git.exe is sitting in the project root, Cursor runs it. No click, no approval dialog, no warning that anything in the folder is about to execute. Whatever that binary does, it does as you, with your source, your SSH keys and your cloud tokens. Cursor keeps re-running it for as long as the project stays open. No prompt injection, no agent, no model in the loop, and no prior access to the machine: opening the folder is the entire exploit, and the result is arbitrary code execution as the logged-in user. AI security firm Mindgard reported the flaw to Cursor on December 15, 2025 and  published full technical details  on Tuesday, seven months later. There is still no patch, and Cursor has published no advisory for the issue. The mechanism takes about a sentence. Cursor checks several locations for a Git binary when a project loads, and one of them is the workspace itself. Process Monitor output in t...

Four compromised npm packages in the @asyncapi namespace have been observed distributing a multi-stage botnet loader, according to findings from OX Security , SafeDep , Socket , and StepSecurity . The affected packages are listed below - @asyncapi/generator-helpers@1.1.1 @asyncapi/generator-components@0.7.1 @asyncapi/generator@3.3.1 @asyncapi/specs(v6.11.2, v6.11.2-alpha.1) "The compromised packages deploy an obfuscated first-stage payload that downloads an encrypted second-stage payload, identified as Miasma, from IPFS," Socket said. The poisoned packages ship a hidden JavaScript implant, with each of them containing an injected source file that decodes to the same second-stage downloader. Unlike previous iterations that leveraged install hooks to trigger the execution of a JavaScript payload, the malicious code in this case is run when the infected module is loaded by Node.js, after which it launches a detached background node that downloads and execute...

SonicWall has warned of active exploitation of two zero-day vulnerabilities impacting Secure Mobile Access (SMA) 1000 series appliances, one of which could be exploited to achieve arbitrary command execution. The vulnerabilities are listed below - CVE-2026-15409 (CVSS score: 10.0) - A Server-side request forgery (SSRF) vulnerability that a remote unauthenticated attacker could exploit to potentially cause the appliance to make requests to an unintended location. CVE-2026-15410 (CVSS score: 7.2) - A post-authentication code injection vulnerability rooted in the Appliance Management Console (AMC) that a remote authenticated attacker could exploit to execute arbitrary operating system commands as administrator under certain conditions. SonicWall said it has "investigated multiple cases indicating the active exploitation of the vulnerabilities," urging customers to apply the fixes as soon as possible. The patches are available in the following versions - 1...

Microsoft shipped its largest Patch Tuesday on record today, and two of the fixes close holes that attackers are already exploiting. The release covers 622 of Microsoft's own CVEs by its  Security Update Guide  count, more than triple  June's previous high of around 200 . Those two live bugs are the ones to grab first. Microsoft credits incident responders for both. Both are elevation-of-privilege flaws in identity and collaboration infrastructure: CVE-2026-56164 in on-premises SharePoint Server and CVE-2026-56155 in Active Directory Federation Services. Neither is one of the splashy remote code execution criticals. They are privilege bugs in two systems that matter more than their scores suggest: the company document store, and the box that signs its logins. The two zero-days to patch first CVE-2026-56164 , a SharePoint Server flaw Microsoft says is being exploited in attacks, lets an unauthenticated attacker escalate privileges over the ne...

SAP has rolled out updates to address multiple vulnerabilities as part of its July 2026 security updates, including a critical flaw in SAP NetWeaver Application Server ABAP. The vulnerability in question is CVE-2026-44747 (CVSS score: 9.9), an out-of-bounds write flaw that allows an authenticated attacker to leverage logical errors in memory management to cause a memory corruption that could lead to unauthorized data access, modification, or system unavailability. "As a temporary workaround the note proposes to disable all ICF nodes with a specific property in transaction SICF," SAP security firm Onapsis said . "Since the workaround will disable opening transactions in SAP GUI for HTML, it is not an option for all customers and it is strongly recommended to install the patching ABAP Kernel version." Also addressed by SAP are two other critical vulnerabilities - CVE-2026-27690 (CVSS score: 9.1) - An HTTP request/response smuggling flaw in SAP Approuter...

Any other browser extension that can run a script on claude.ai can still trigger Claude for Chrome tasks aimed at your Gmail, your latest Google Doc and its comments, and your Calendar. Both this and ClaudeBleed need a rogue extension that can already run a script on claude.ai; the difference is scope. Anthropic restricted the arbitrary-prompt path in May as part of its response to the  ClaudeBleed  flaw, boxing external callers into a fixed set of tasks, but  Manifold Security  says the gap is still open in v1.0.80, the current release, eight versions later. If you run Claude for Chrome and any other extension that can touch claude.ai, you are in scope. In the default "ask before acting" mode, the forged task still hits an approval box you have to click. If you switched on "Act without asking," the hands-off automation mode, it runs with no prompt at all. The quickest guard is to turn "Act without asking" off and review any extension with permissio...

Cybersecurity researchers have flagged a previously undocumented Rust-based remote access trojan (RAT) codenamed LabubaRAT that masquerades as NVIDIA software to blend into target environments. "LabubaRAT creates a reusable foothold for hands-on activity," Blackpoint Cyber researchers Sam Decker and Nevan Beal said in an analysis published today. "Once deployed, it can profile the host, identify security tools, receive operator commands, move files, capture screenshots, and proxy traffic through the affected system." The implant also supports multiple communication methods, including HTTPS, WebView2, and DNS tunneling, allowing attackers to maintain access to compromised hosts even if one pathway is detected and closed off. There are some signs that LabubuRAT is being offered under a malware-as-a-service (MaaS) model. The starting point of the attack chain is an executable named "nvidia-sysruntime.exe," which impersonates NVIDIA's container ru...

Cybersecurity researchers have disclosed details of two access control-related flaws impacting the RabbitMQ message broker service that could allow attackers to leak OAuth client secrets, expose enterprise messaging infrastructure to takeover risks, and bypass tenant boundaries. Miggo's security team, which discovered and reported the flaws, said one "leaks the broker's confidential OAuth secret to an unauthenticated attacker in a single request, a direct path to full broker takeover in the configurations that use that secret." The second vulnerability allows any logged-in user to silently read other tenants' data. Both shortcomings are said to have been present in the codebase since early 2024, impacting RabbitMQ release lines from 3.13.0 and later. They have been addressed in versions 4.3.0, 4.2.6, 4.1.11, 4.0.20, and 3.13.15. There is no evidence of active exploitation of either of the vulnerabilities prior to the public disclosure.
