Multiple vulnerabilities in five popular AI developer tools could allow attackers to execute code on a host machine, read and steal files, or spoof browser address bars. Researchers say flaws in OpenAI's Codex and Microsoft's VS Code remain unpatched, potentially putting developers who use affected configurations at risk. AI security startup Forever Security discovered vulnerabilities in Cursor, GitHub Copilot, Anthropic's Claude Desktop, VS Code, and Codex, and disclosed four of the flaws to the affected vendors. GitHub independently fixed the Copilot vulnerability without receiving a report from Forever Security. All five share a common security weakness: embedded browsers granted capabilities beyond those available to conventional browsers. Each tool “enriched its embedded browser beyond what a normal browser allows, and those enrichments undermined the traditional threat model - as agent input, as the authority on a tab’s own address, or as reach onto the host,” Forever researcher Gal Weizman wrote in a Thursday report. Forever dubbed this class of vulnerability “Embrace,” short for EMbedded BRowser, and said the flaws led to code execution in Cursor, data theft in Claude Desktop, Codex, and VS Code, and address bar spoofing in GitHub Copilot. Here’s what each of these looks like, starting with Cursor. Cursor: arbitrary code execution Typical web pages can’t run commands on the host computer because a web page’s JavaScript cannot talk to local apps. Cursor’s integrated browser, however, allows a page to call the agent’s composer. The agent reads this as instructions and follows them, but the instructions remain hidden from human users. This opens the coding agent up to prompt injection attacks that could allow an attacker to execute commands on the host machine. The researchers disclosed the vulnerability to Cursor on September 10, and the vendor silently patched the flaw on October 1. According to Forever, Cursor did not publish a security advisory about the issue or respond to the researchers' disclosure. Cursor also did not reply to The Register’s request for comment. GitHub Copilot: address bar spoofing Under normal browser operations, a webpage cannot change the content of the address bar. “Copilot’s browser preview works differently,” Weizman wrote. “Some pages change their address without loading a new page, and the app cannot always see that. So Copilot let the page tell the app its own address.” The app checked only whether the text looked like a web address, starting with http, https or file, but it didn’t check where the tab really pointed to. This can be abused to trick the embedded browser into displaying a spoofed URL - such as github.com/login - in the address bar, while loading a fraudulent website - like a phishing page - underneath. The researchers found the address-bar spoofing flaw in GitHub Copilot 1.1.27 on September 26. GitHub independently fixed the flaw in a later Copilot build (1.1.29) on October 13 without receiving a vulnerability report from Forever. We reached out to GitHub and did not receive a response. Claude Desktop, Codex, and VS Code: arbitrary file read All three of these vendors’ coding assistants allow local HTML files opened in the built-in browser to escape its boundaries and access other files. Both Claude Desktop and VS Code allow local pages access to their respective project folders, but the researchers found that these restrictions did not apply to web workers – a browser feature that allows JavaScript to run in a background thread, separate from the page's main thread. This means a local page can start a worker, and the worker can bypass restrictions to reach any file on the machine. Codex, however, didn’t have this same restriction, meaning a local page could read any file directly without a worker. Weizman said his team disclosed the issue to Anthropic on July 23, and the AI vendor declined the Claude Desktop bug report as invalid for a “workspace trust” gated security boundary. A day later, however, Noma Security reported the same flaw, according to Weizman, and Anthropic accepted the report as valid. Anthropic did not respond to The Register’s questions about either bug report or Forever’s timeline of events. Forever disclosed the Codex bug to OpenAI on July 27 and didn’t get a response. The flaw remains unpatched, but an OpenAI spokesperson told The Register that it's aware of the issue and working to address it. On September 10, Forever disclosed the VS Code vulnerability to Microsoft and says the vendor also labeled it as an invalid workspace trust gated security boundary issue. The researchers claim it remains unpatched. Microsoft did not respond to our request for comment.®

Some attacks take real skill. Others just need someone to leave a door open. This week has both. Exposed passwords, old bugs still getting exploited, and trusted software doing things it shouldn't. There's a strange mix of clever tricks and careless mistakes. Hackers are borrowing trust from familiar apps, websites, and AI tools. Some are using AI to speed things up.

Suspected Chinese attackers chained PHP2Shell with a Linux kernel privilege-escalation exploit to root 25 servers, including Palo Alto Networks firewalls linked to US government-affiliated organizations, according to Dream researchers. The snoops began exploiting these servers on October 23, targeting organizations across the US, Japan, Taiwan, and South Korea. The attackers also honed in on US government-affiliated firewalls. “Within hours of compromising a US government-affiliated firewall, they had tunneled into the internal network, compromised a third server using the same PHP2Shell exploit, and launched a full Active Directory attack campaign - all through a chain that started with a single unauthenticated HTTPS request to a management interface that should never have been exposed to the internet,” the Israeli AI cybersecurity startup said in a report. Plus, the attackers “likely still” have persistent, remote access to compromised organizations’ networks, Dream noted. The attackers rooted the first US government-affiliated firewall on October 23, but the device crashed shortly afterward, possibly due to around 900 MB of exploit traffic. According to Dream, it remained unresponsive despite 240 automated checks over two hours. They successfully exploited the second firewall a day later, on October 24. The compromised firewalls ran vulnerable versions of Palo Alto Networks' PAN-OS. Dream said it had been working with the vendor to investigate the compromises, and Palo Alto Networks' Unit 42 researchers independently verified the attacker's tooling and confirmed Dream's reported results. To break into the firewalls, the attackers built a custom exploit chain that includes PHP2Shell and a Fragnesia kernel flaw, and ran about 40 custom post-exploitation scripts once they were inside the targeted organizations. Total attack chain in under 15 minutes PHP2Shell, comprised of CVE-2026-109618 and CVE-2026-109619, came to light early last week, along with fears that attackers would abuse the bugs to take down most of the internet. Despite “hundreds” of PHP2Shell proof-of-concept repositories on GitHub, the first reports of successful attacks didn’t start until Saturday. Both bugs have CVSS scores of 9.2 and can be exploited without authentication to run code on vulnerable PHP servers. The PHP2Shell exploit recovered by Dream was not a copy of any known public exploit. It “appears to have been independently developed and tailored specifically for the targeted firewall platform,” the researchers wrote. The attackers combined PHP2Shell with Fragnesia (CVE-2026-46300), a high-severity local privilege-escalation vulnerability affecting the Linux kernel's XFRM ESP-in-TCP subsystem. The US Cybersecurity and Infrastructure Security Agency (CISA) added this Linux kernel bug to its catalog of Known Exploited Vulnerabilities on Wednesday. Both CISA and the FBI declined to comment. The miscreants developed a four-stage PHP2Shell exploit that allowed them to execute commands without authentication on vulnerable Palo Alto Networks firewalls. They then used Fragnesia to escalate their privileges and gain root access. The attackers targeted PAN-OS 12.1 and 12.2, which run PHP 8.0.30 with a high memory limit that enabled the exploit's memory-corruption stages. “The total chain - from unauthenticated HTTPS connection to persistent root webshell - completes in under 15 minutes,” the Dream team wrote. 4 steps to root Here’s how it works: First, they flood the servers with crafted multipart POST requests to corrupt PHP’s memory, and force a predictable memory layout. Then a second request forges the stale session ID length from the memory corruption part of the attack, forcing an out-of-bounds read and exposing the base address of libphp.so in the running process. The attackers then exhaust PHP's memory again to force mod_data=NULL, creating a stale reference they can forge in the final stage to execute commands as the nobody user. They use Fragnesia to escalate to root and plant a web shell in a publicly accessible directory on the firewall. After breaking in via the compromised firewalls, the attackers snooped around in Active Directory, stealing credentials and other sensitive information. With root access, the attackers also had the master key to decrypt the LDAP service account password, which they hardcoded into every subsequent script. They also enumerated every user and group in the domain via LDAP queries, and sprayed passwords against every user account. Attackers also tried to create backdoor AD accounts and attempted SAML signing key extraction - but Dream doesn’t know if these were successful. “The attack results - whether the password spray found valid credentials, whether the backdoor accounts were created, whether SAML keys were extracted - stayed on the management server's local filesystem and were not among the artifacts we recovered,” the researchers noted. AI tools in the attack The investigation also uncovered evidence that the attackers used AI tools, but noted that this was not a fully autonomous attack. The researchers found Anthropic's Claude Code installed, an AI-powered offensive security platform called aiscan configured with Chinese models DeepSeek and Kimi, and API keys for the FOFA reconnaissance service. FOFA is a Chinese internet asset search engine similar to Shodan. The attackers used it to identify about 19,000 internet-facing Palo Alto Networks firewalls worldwide. “The persistent tunnel into the US government organization is likely still running,” Dream warned. “And the attacker still has 19,000 fingerprinted targets they can revisit as they develop profiles for additional PAN-OS versions.”®
