Unpatched Kaltura mwEmbed Flaws Could Let Remote Attackers Read Files and Run Code

Unpatched Kaltura mwEmbed Flaws Could Let Remote Attackers Read Files and Run Code

Aug 26, 2026 Vulnerability / Web Security
The CERT Coordination Center (CERT/CC) has disclosed two unpatched vulnerabilities in Kaltura's HTML5 video player library that allow a remote, unauthenticated attacker to read arbitrary files from a server and execute code on it. The flaws, tracked as CVE-2026-19913 and CVE-2026-19912 , both stem from the same unsafe deserialization in the mwEmbedLoader.php endpoint of the mwEmbed player library, which Kaltura also distributes as html5lib. Neither requires authentication or a Kaltura session token, and network access to the endpoint is the only precondition CERT/CC states. No patch is available, and CERT/CC said it was "unable to reach Kaltura to coordinate these vulnerabilities." Administrators are advised to restrict or disable external access to the endpoint and to enforce a strict allow-list for the ServiceUrl parameter that permits only legitimate backend API URLs. No exploitation had been reported at the time of writing, and neither CVE appeared in CISA...
Claude Opus 4.6 Bypasses Gym Booking Limit, Cancels Other Users' Reservations in Tests

Claude Opus 4.6 Bypasses Gym Booking Limit, Cancels Other Users' Reservations in Tests

Aug 26, 2026 AI Security / Application Security
Aikido Security has published research that recreates the Australian gym-booking incident in a synthetic environment, finding that Claude Opus 4.6, running on the OpenClaw agent harness, exploited a client-side-only booking restriction in 9 of 10 runs. The original incident was first reported by ABC News on August 10, based on chat logs and screenshots the user supplied. He had asked an OpenClaw agent running Opus 4.6 to book him into a gym class. The agent booked sessions months beyond the window the site allowed. It then tested, without being asked, whether the same API would let it cancel another member's waitlist entry. The test removed the person holding the top place and moved the user up one position. The agent told him it could not add the member back. Aikido's test system is a single-page web application backed by a GraphQL API carrying the two flaws described in the original incident. The seven-day booking window is enforced only in the frontend, and the cancel...

A Malicious Webpage Could Poison Your Local AI Model Behind NVIDIA NemoClaw

Aug 25, 2026 AI Security / Vulnerability
Oasis Security has disclosed a weakness in NVIDIA NemoClaw that could let an attacker-controlled webpage take unauthenticated control of the local Ollama instance serving an AI agent and plant hidden instructions inside the model itself. The findings were shared with The Hacker News ahead of publication, and the report says Oasis Security reported them to NVIDIA's Product Security Incident Response Team (PSIRT) beforehand. The research carries no CVE identifier. No exploitation has been reported as of August 25, 2026. Oasis Security's head of research, Elad Luz, told The Hacker News that NemoClaw v0.0.35 fixed the issue on macOS and Linux. There is no fix on the Windows and WSL path, according to Luz, where v0.0.34 added a Windows installation that carries a warning instead. NemoClaw is NVIDIA's open source reference stack for running agents such as OpenClaw inside its OpenShell sandboxes, and Ollama is one of its supported local inference backends. The report des...

24 npm Packages Abuse unpkg Mirrors to Host Fake Cloudflare CAPTCHA Pages

Aug 25, 2026 Phishing / Threat Intelligence
Cybersecurity researchers have disclosed details of a new campaign that uses a cluster of 24 npm packages as free phishing infrastructure for redirecting to ClickFix-style fake CAPTCHA pages. "While the malware is simply a single HTML page inside the npm package, and while downloading it wouldn't do harm, the threat actor’s use of npm isn't to infect developers who install it, but to use the registry and its mirrors as a safe, validated storage for the malware," OX Security researchers Moshe Siman Tov Bustan and Vitalii Chepurko said . The list of npm packages, some of which are still available for download, is below - bgzxcuite2 prezdentkxheiw egair0810 mnteckets airdzticket egypt0811 passport811 vxhjkseuiaqkb ndmushdkeqe ndmxchdjxn2 ndmfguyhoxc3 mjsdqwocvn m2fcsfyjkuxb m3fdfocdoewn @worrisome/reutil testdgdbcsd tesgfvbncsdbcv mndsxcusiwlk1 mn2adskhweox mn3sadkoiewu mn4xcouzvhus mbxcnsuwgs1 s...

Shipping More AI Code Than You Can Secure? Watch How to Control Remediation Debt

Aug 24, 2026 AI Security / Webinar
If your developers are using AI coding tools, you are probably already seeing the upside: faster development, more code, and less time spent on routine work. The harder part is what comes after. AI can also introduce open-source packages at a pace your security team was never built to handle. More dependencies mean more vulnerabilities to review, more remediation work, and a backlog that can quietly keep growing. Our latest AI Coding and Open Source Risk webinar examines what this means for security and engineering teams, drawing on data from 300 enterprise leaders. The Real Problem Is What AI Adds to Your Stack AI coding itself is not the issue. The problem is how quickly generated code can bring new open-source components into your environment. A developer can add a dependency in minutes. Your team may then need to assess vulnerabilities, licensing, maintenance, ownership, and whether that package should be there at all. That work does not disappear just because the co...

The Outsized Shadow: Why 5% of AI Users Are Your Biggest Security Risk

The Outsized Shadow: Why 5% of AI Users Are Your Biggest Security Risk

Aug 24, 2026 Artificial Intelligence / Browser Security
Big security risks come in small packages. While enterprise security teams focus on policing the proliferation of employees using ChatGPT and Claude for quick drafting tasks, a more urgent threat is posed by a handful of AI super-adopters who are quietly hardcoding unvetted tools into critical business operations. According to new research published by Akamai, the top 5% of enterprise power users interact with AI models at 12 times the rate of the bottom 50% of the workforce. The findings, published in Akamai’s State of the Internet: Enterprise AI Usage Risk Report 2026 , are based on real-world usage and telemetry data as well as research and threat analysis.  These AI super-adopters are creating a disproportionate security risk by expanding the use of shadow AI, increasing opportunities for data leakage, and introducing autonomous AI agents that operate within the enterprise but outside its established guardrails. “Small groups of AI power users are casting outsized shado...

New Cryptographic Context Injection Attack Could Let Web Pages Steal Grok Chat Data

New Cryptographic Context Injection Attack Could Let Web Pages Steal Grok Chat Data

Aug 20, 2026 Artificial Intelligence / Data Security
Adversa AI has disclosed an attack technique that it says can cause xAI's Grok chatbot to send a user's name, approximate location, subscription tier, and the prompts from the ongoing conversation to an attacker-controlled server after the user asks it to summarize an ordinary web page. The AI security company, which has codenamed the technique "Cryptographic Context Injection ," said the transfer completed without a confirmation step and with no visible warning in its proof-of-concept demonstration. There is no patch, no CVE identifier, and no user-facing workaround, and the writeup does not report any exploitation in the wild. Asked which build was tested, Adversa told The Hacker News the target was the Grok web chat at grok.com running Grok 4.5 Fast, and that the attack was reproduced once on August 19, 2026. The writeup gives no success rate. The company said it has attempted the attack 20 times since June with a 40% success rate, and that the failures cam...

Isolated-vm Flaw Lets Sandboxed JavaScript Escape to Host for Potential RCE

Aug 20, 2026 Vulnerability / Application Security
Cybersecurity researchers have disclosed a critical security flaw in isolated-vm , a popular open-source sandbox with more than 2,900 stars and 190 forks on GitHub, that could allow attackers to escape the confines of the isolated environment. The vulnerability (" GHSA-864f-rcv7-6rh4 "), which has yet to be assigned a CVE identifier, impacts all versions of the library before and including 7.0.0. It has been patched in versions 6.2.0 and 7.0.1 released earlier this month. Isolated-vm is a Node.js library for running untrusted JavaScript inside a V8 Isolate , an independent instance of the Google V8 JavaScript engine, allowing multiple sandboxed JavaScript environments to run concurrently without sharing data or interfering with each other. The npm package has witnessed nearly 1 million downloads over the past week. Because each V8 Isolate has a separate state and maintains its own heap, it is not possible to directly pass JavaScript objects from the main Node.js threa...
CDN Tsunami Attack Abuses HTTP/3 Translation for Up to 350x DoS Amplification

CDN Tsunami Attack Abuses HTTP/3 Translation for Up to 350x DoS Amplification

Aug 20, 2026 Web Security / Vulnerability
Cybersecurity researchers have disclosed two denial-of-service (DoS) attacks that exploit how major content delivery networks (CDNs) convert client-facing HTTP/3 traffic into HTTP/1.1 requests to the websites they front, amplifying a low-bandwidth request stream by up to 350x against the origin server. The attacks, collectively named " CDN Tsunami ," were evaluated against Alibaba, Baidu, Cloudflare, Amazon CloudFront, Fastly, and Tencent. All six were found susceptible to the bandwidth variant and five to the connection variant, with Cloudflare unaffected by the latter because it buffers the complete request before opening a connection to the origin. The attack requires a website hosted on one of the six providers, with HTTP/3 serving at the edge, and no configuration changes on the website's part. The paper lists HTTP/3 as enabled by default at Cloudflare and CloudFront. However,  Cloudflare's documentation  describes HTTP/3 as available on all plans and pr...
NASA AIT-GUI Flaws Could Let Unauthenticated Attackers Issue Spacecraft Commands

NASA AIT-GUI Flaws Could Let Unauthenticated Attackers Issue Spacecraft Commands

Aug 20, 2026 Vulnerability / Critical Infrastructure
Security researchers at Cycode have disclosed a chain of flaws in AIT-GUI, the browser-based operator console for NASA/JPL's open-source AMMOS Instrument Toolkit, that allow an unauthenticated attacker to issue arbitrary commands to the software's spacecraft and instrument command bus. The chain, tracked as GHSA-p9r8-2q67-fp86 and rated 9.4 on the CVSS v3.1 scoring system, impacts AIT-GUI versions 2.5.1 and earlier, with the advisory listing version 2.5.2 as the fixed release. The advisory, published August 13, 2026, states that no CVE has been assigned to it. The AMMOS Instrument Toolkit is a framework for building ground data systems, the software that sends commands to instruments and spacecraft and processes the telemetry coming back down. AIT-GUI is its operator console, and the endpoints in question relay operator commands to a command bus. "The blast radius of an unauthenticated POST is measured in issued instrument commands, not defaced pages," Cycode ...
Elementor Pro Flaw Could Let Unauthenticated Attackers Upload PHP and Execute Code

Elementor Pro Flaw Could Let Unauthenticated Attackers Upload PHP and Execute Code

Aug 20, 2026 Vulnerability / Web Security
Cybersecurity researchers have disclosed details of a critical flaw in the Elementor Pro WordPress plugin that, if successfully exploited, could lead to remote code execution. The vulnerability, tracked as CVE-2026-32475 , carries a CVSS score of 9.0 out of 10.0. It has been described as a case of unrestricted upload of a file with a dangerous type. "The flaw lives in the Forms module's File Upload field, where the extension check and the file-move step run in two separate loops with different handling of empty file entries," Patchstack said . "By submitting two file parts for the same field, an unauthenticated attacker skips the extension blocklist entirely and writes a PHP file into a public directory." This discrepancy in how it validates the file's extension and moves the uploaded file to a public directory when empty file entries are processed turns a restricted file-upload field into an unauthenticated remote code execution primitive. Succes...
Cloudflare Workers Spectre Attack Leaks JWT From Co-Located Worker at 12 Bits/Second

Cloudflare Workers Spectre Attack Leaks JWT From Co-Located Worker at 12 Bits/Second

Aug 19, 2026 Cloud Security / Vulnerability
Cybersecurity researchers have disclosed details of a  remote Spectre attack  against Cloudflare Workers that leaked a JSON Web Token (JWT) from a co-located Worker in the production environment at up to 12 bits per second, 360 times the rate of an earlier attack demonstrated in 2021. The end-to-end experiment used an attacker Worker and a victim Worker controlled by the researchers, with the JWT intentionally placed in the victim's memory. The research paper stated that no customer data was accessed. Cloudflare said the attack has already been mitigated in production after it improved Dynamic Process Isolation (DyPrIs), integrated the  V8 Sandbox , and deployed Memory Protection Keys (MPK)-based in-process isolation, adding that it found no indicators of active exploitation over the last three years. "We demonstrate that the production implementation of DyPrIs was insufficient," the researchers said in  the paper . Cloudflare Workers runs code from multiple...
Clop-Linked Windchill Web Shell Decrypts Credentials and Maps Engineering Data

Clop-Linked Windchill Web Shell Decrypts Credentials and Maps Engineering Data

Aug 19, 2026 Vulnerability / Ransomware
A JavaServer Pages (JSP) web shell deployed following the exploitation of a critical security flaw in PTC Windchill and FlexPLM servers is specifically designed for the enterprise Product Lifecycle Management (PLM) software, according to new findings from ReliaQuest. The cybersecurity company characterized the web shell as a fully equipped extortion platform capable of mapping sensitive vault data, decrypting every credential in the Windchill keystore, and running additional code by means of a custom Java class loader, turning the tool into a backdoor for remote access and post-exploitation activity, such as lateral movement, ransomware, or persistence. While threat actors are typically known to deploy lightweight web shells (or reuse open-source variants like Behinder or China Chopper) as a way to maintain remote access to compromised systems and enable basic command execution capabilities, the latest development signals the use of a bespoke web shell that's tailored to the ...
