Critical Next.js ImageResponse Flaw Can Lead to Server Code Execution via Crafted SVG Input

A new security vulnerability in Next.js could allow attackers to run code on a server via  ImageResponse , the feature that generates Open Graph and other social preview images, Vercel said. The risk applies when an app puts values an attacker controls, such as text read from the request URL, into the image. Vercel, which develops Next.js,  fixed the flaw  on September 22 in version 16.3.6. The flaw, tracked as CVE-2026-94545 , affects Next.js 16.2.0 through 16.3.5 when ImageResponse runs on the Node.js runtime, which Next.js  uses by default . Vercel's  advisory  rates it critical, with a CVSS score of 9.5. The Edge version of ImageResponse is not affected, and neither is Next.js 15. ImageResponse uses  Satori , a Vercel library, to convert the image layout into SVG code before the final PNG is generated. Affected apps are those that "pass attacker-controlled values into SVG content, attributes, or styles during image generation", according to ...

ShinyHunters Claims FBI Breach, Says It Stole Data on Agents and Job Applicants

The cyber extortion group known as ShinyHunters on Tuesday claimed it had breached the U.S. Federal Bureau of Investigation and stolen data belonging to current and former employees at the agency. "We have compromised the FBI. We hold very sensitive data on almost ALL FBI Agents and individuals who filed an application with the FBI for a job," the group said in a statement posted on their dark web site. "Whether it be a Special Agent or any other role within your agency. The following FBI services were compromised: Criminal Justice (CJ), HR, Medlink, and more." The development was first reported by 404 Media. ShinyHunters said the FBI was targeted in response to a May 2026 public service announcement (PSA) that detailed the threat actor's targeting of Canvas , an online Learning Management System (LMS), while urging victims not to pay. The attackers, in their own counter PSA, described them as "substantial false allegations," adding, "w...

Check Point Warns of Management Server Zero-Day Exploited in Targeted Attacks

Attackers exploited a previously unknown flaw in Check Point's Security Management Server in a handful of targeted attacks on July 23,  the company said . The flaw, CVE-2026-93616 , allows an attacker who can access the server's web service to run scripts on it without logging in. Check Point released a fix on September 22 for the server that controls firewall policies for the Check Point gateways it manages. Separately,  Check Point said  attackers have been trying since September 12 to exploit a VPN flaw it  fixed on September 9 . The attempts, against a flaw tracked as CVE-2026-85102, have targeted customers of Spark, Check Point's firewall line for small businesses. When the fix came out, Check Point had no evidence the flaw was being exploited. CVE-2026-93616 is a path traversal bug in the management server's web service. The service does not properly limit which files and folders a request can reach. An attacker can use it to upload scripts to the s...

WordPress Issues Patch for Critical Flaw That Can Enable Code Execution on Some Servers

WordPress has fixed a critical flaw in its core software that lets an attacker with no account make a site load a PHP file from outside its theme folders. On some servers, that can go further, allowing the attacker to run their own code. The fix shipped on September 22 in WordPress 7.1.2, with fixes for every branch the project still supports, back to 4.7, and WordPress is telling site owners to  update now . WordPress rates the flaw as critical, assigns it a CVSS score of 9.2, and assigns it  CVE-2026-87902 . Reaching it requires no account and no action from a logged-in user. Every version from 4.7.0 through 7.1.1 is affected. That includes 7.1.1, from WordPress's  September 17 security release , so a site updated less than a week ago still needs this one. It is a separate flaw from the ones that the release fixed.

Malicious npm Package Poses as Twilio Bug-Bounty Probe, Can Exfiltrate Credentials

Cybersecurity researchers have disclosed details of a malicious npm package named "tw-pkgprobe-7731" that masquerades as a security tool targeting developers integrating Twilio into their applications, while stealthily attempting to harvest sensitive data. The package, named "tw-pkgprobe-7731," was first uploaded to the npm registry in mid-August 2026 by an npm account named "twdepprobe7731." In total, 11 versions of the package were published in quick succession on the same day over an approximately 45-minute time period. The npm user account no longer exists as of writing. "The first version of tw-pkgprobe-7731 posed as an authorized security research probe," ReversingLabs researcher Lucija Valentić said in a report published today. "Comments inside the package describe it as an 'Authorized bug-bounty research probe (Twilio HackerOne program)' that 'runs only inside Twilio's serverless packager sandbox' and ...

Microsoft Takes Down EvilTokens Device-Code Phishing Service Tied to 12,000 Inbox Compromises

Microsoft on Tuesday announced the takedown of the EvilTokens device code phishing service that it said used artificial intelligence (AI) "at every step of the attack chain." The action, carried out with authorization from the U.S. District Court for the Eastern District of Virginia, involved the efforts of Health-ISAC, alongside Cloudflare , Coinbase, OpenAI, Railway, SpyCloud, The Shadowserver Foundation, and TRM Labs. Microsoft is tracking the threat actors behind the development and support of EvilTokens as Storm-2992 . In tandem, the Metropolitan Police Service arrested two men, aged 32 and 38, on September 11, 2026, in connection with the illicit commercial operation. The tech giant described EvilTokens as a "powerful cybercrime platform" that used AI to compromise email accounts and design roadmaps for financial fraud and scams. "While EvilTokens helped cybercriminals access email accounts, at the center of the service was an AI-style chatbot t...

Critical Bifrost AI Gateway Flaw Lets Attackers Run Commands Without Credentials

A critical vulnerability in  Bifrost , an open-source AI gateway that routes requests to more than 20 LLM providers, allows an unauthenticated attacker to run arbitrary commands on the gateway server with a single HTTP request. The flaw, tracked as  CVE-2026-90898  (CVSS score: 9.8), affects all versions of the Bifrost HTTP transport before 2.1.0 when management authentication is disabled, which is the default configuration. A fix is available in transports/v2.1.0. Yuval Moravchick of  JFrog Security Research , who discovered the flaw, said an attacker can register a stdio-type MCP client through a single unauthenticated POST to the management API endpoint /api/mcp/client. Bifrost starts the specified command immediately, before any MCP handshake, as the gateway process user. On the official Docker image, that user is appuser. Because the gateway stores API keys for every connected provider, executing commands on the gateway process grants the attack...

Researcher Drops BigDiskBuster Zero-Day PoC That Blocks Microsoft Defender Updates

A zero-day proof-of-concept tool that stops Microsoft Defender from installing platform and signature updates by filling all available disk space was  published on GitHub  on September 19. The tool, called BigDiskBuster , has no patch, no CVE, and no Microsoft advisory. Its author, Abdelhamid Naceri, is a former Microsoft security researcher whose earlier Defender exploits were used in attacks. When updates are blocked, Defender keeps running, but its detection content grows stale. The researcher's screenshot shows Defender returning a generic Windows error when trying to update, but whether the failure raises an automatic alert is not clear from the proof-of-concept alone. Naceri said he was dismissed from Microsoft's Security Response Center in 2024 and has been releasing exploits without coordinating with the company since April. His first three Defender tools — BlueHammer, RedSun, and UnDefend — were all  exploited in live intrusions  before Microsoft...
