Millions of WordPress websites are at risks of being completely hijacked by the hackers due to a critical cross-site scripting (XSS) vulnerability present in the default installation of the widely used content management system. The cross-site scripting (XSS) vulnerability, uncovered by the security researcher reported by Robert Abela of Security firm  Netsparker . Wordpress vulnerability resides in Genericons webfont package that is part of default WordPress Twenty Fifteen Theme. Here comes the threat: The XSS vulnerability has been identified as a " DOM-based ," which means the flaw resides in the document object model (DOM) that is responsible for text, images, headers, and links representation in a web browser. The easy-to-exploit DOM-based Cross-Site Scripting (XSS) vulnerability occurred due to an insecure file included with Genericons that allowed the Document Object Model Environment in the victim's browser to be modified. What's DOM-Bas...

Popular password manager plugins for web browsers have been found susceptible to clickjacking security vulnerabilities that could be exploited to steal account credentials, two-factor authentication (2FA) codes, and credit card details under certain conditions. The technique has been dubbed Document Object Model ( DOM )-based extension clickjacking by independent security researcher Marek Tóth, who presented the findings at the DEF CON 33 security conference earlier this month. "A single click anywhere on an attacker-controlled website could allow attackers to steal users' data (credit card details, personal data, login credentials, including TOTP)," Tóth said . "The new technique is general and can be applied to other types of extensions." Clickjacking , also called UI redressing, refers to a type of attack in which users are tricked into performing a series of actions on a website that appear ostensibly harmless, such as clicking on buttons, when, in rea...

A maximum-severity security flaw has been disclosed in React Server Components (RSC) that, if successfully exploited, could result in remote code execution. The vulnerability, tracked as CVE-2025-55182, carries a CVSS score of 10.0. The vulnerability has been codenamed React2shell . It allows "unauthenticated remote code execution by exploiting a flaw in how React decodes payloads sent to React Server Function endpoints," the React Team said in an alert issued today. "Even if your app does not implement any React Server Function endpoints, it may still be vulnerable if your app supports React Server Components." According to cloud security firm Wiz , the issue is a case of logical deserialization that stems from processing RSC payloads in an unsafe manner. As a result, an unauthenticated attacker could craft a malicious HTTP request to any Server Function endpoint that, when deserialized by React, achieves execution of arbitrary JavaScript code on the server. ...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday formally added a critical security flaw impacting React Server Components (RSC) to its Known Exploited Vulnerabilities ( KEV ) catalog following reports of active exploitation in the wild. The vulnerability, CVE-2025-55182 (CVSS score: 10.0), relates to a case of remote code execution that could be triggered by an unauthenticated attacker without requiring any special setup. It's also tracked as React2Shell. "Meta React Server Components contains a remote code execution vulnerability that could allow unauthenticated remote code execution by exploiting a flaw in how React decodes payloads sent to React Server Function endpoints," CISA said in an advisory. The problem stems from insecure deserialization in the library's Flight protocol, which React uses to communicate between a server and client. As a result, it leads to a scenario where an unauthenticated, remote attacker can execute arbi...

The React team has released fixes for two new types of flaws in React Server Components (RSC) that, if successfully exploited, could result in denial-of-service (DoS) or source code exposure. The team said the issues were found by the security community while attempting to exploit the patches released for CVE-2025-55182 (CVSS score: 10.0), a critical bug in RSC that has since been weaponized in the wild . The three vulnerabilities are listed below - CVE-2025-55184 (CVSS score: 7.5) - A pre-authentication denial of service vulnerability arising from unsafe deserialization of payloads from HTTP requests to Server Function endpoints, triggering an infinite loop that hangs the server process and may prevent future HTTP requests from being served CVE-2025-67779 (CVSS score: 7.5) - An incomplete fix for CVE-2025-55184 that has the same impact CVE-2025-55183 (CVSS score: 5.3) - An information leak vulnerability that may cause a specifically crafted HTTP request sent to a vulnerable...

Think payment iframes are secure by design? Think again. Sophisticated attackers have quietly evolved malicious overlay techniques to exploit checkout pages and steal credit card data by bypassing the very security policies designed to stop them. Download the complete iframe security guide here .  TL;DR: iframe Security Exposed Payment iframes are being actively exploited by attackers using malicious overlays to skim credit card data. These pixel-perfect fake forms bypass traditional security, as proven by a recent Stripe campaign that has already compromised dozens of merchants. This article explores: Anatomy of the 2024 Stripe skimmer attack. Why old defenses like CSP and X-Frame-Options are failing. Modern attack vectors: overlays, postMessage spoofing, and CSS exfiltration. How third-party scripts in payment iframes create new risks. How the new PCI DSS 4.0.1 rules are forcing merchants to secure the entire page. A six-step defense strategy focusing on real-time mon...

React2Shell continues to witness heavy exploitation, with threat actors leveraging the maximum-severity security flaw in React Server Components (RSC) to deliver cryptocurrency miners and an array of previously undocumented malware families, according to new findings from Huntress. This includes a Linux backdoor called PeerBlight, a reverse proxy tunnel named CowTunnel, and a Go-based post-exploitation implant referred to as ZinFoq. The cybersecurity company said it has observed attackers targeting numerous organizations via CVE-2025-55182, a critical security vulnerability in RSC that allows unauthenticated remote code execution. As of December 8, 2025, these efforts have been aimed at a wide range of sectors, but prominently the construction and entertainment industries. The first recorded exploitation attempt on a Windows endpoint by Huntress dates back to December 4, 2025, when an unknown threat actor exploited a vulnerable instance of Next.js to drop a shell script, follo...

Phishing attacks remain a huge challenge for organizations in 2025. In fact, with attackers increasingly leveraging identity-based techniques over software exploits, phishing arguably poses a bigger threat than ever before.  Attackers are increasingly leveraging identity-based techniques over software exploits, with phishing and stolen credentials (a byproduct of phishing) now the primary cause of breaches. Source: Verizon DBIR Attackers are increasingly leveraging identity-based techniques over software exploits, with phishing and stolen credentials (a byproduct of phishing) now the primary cause of breaches. Source: Verizon DBIR Attackers are turning to identity attacks like phishing because they can achieve all of the same objectives as they would in a traditional endpoint or network attack, simply by logging into a victim's account. And with organizations now using hundreds of internet apps across their workforce, the scope of accounts that can be phished or targeted with s...

React conquered XSS? Think again. That's the reality facing JavaScript developers in 2025, where attackers have quietly evolved their injection techniques to exploit everything from prototype pollution to AI-generated code, bypassing the very frameworks designed to keep applications secure. Full 47-page guide with framework-specific defenses (PDF, free). JavaScript conquered the web, but with that victory came new battlefields. While developers embraced React, Vue, and Angular, attackers evolved their tactics, exploiting AI prompt injection, supply chain compromises, and prototype pollution in ways traditional security measures can't catch. A Wake-up Call: The Polyfill.io Attack In June 2024, a single JavaScript injection attack compromised over 100,000 websites in the biggest JavaScript injection attack of the year. The Polyfill.io supply chain attack , where a Chinese company acquired a trusted JavaScript library and weaponized it to inject malicious code, affected major pl...

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...

An unknown threat actor has been attributed to creating several malicious Chrome Browser extensions since February 2024 that masquerade as seemingly benign utilities but incorporate covert functionality to exfiltrate data, receive commands, and execute arbitrary code. "The actor creates websites that masquerade as legitimate services, productivity tools, ad and media creation or analysis assistants, VPN services, crypto, banking and more to direct users to install corresponding malicious extensions on Google's Chrome Web Store (CWS)," the DomainTools Intelligence (DTI) team said in a report shared with The Hacker News. While the browser add-ons appear to offer the advertised features, they also enable credential and cookie theft, session hijacking, ad injection, malicious redirects, traffic manipulation, and phishing via DOM manipulation. Another factor that works in the extensions' favor is that they are configured to grant themselves excessive permissions via...

If you use an Apple iPhone or a MacBook, we have a piece of alarming news for you. Turns out merely visiting a website — not just malicious but also legitimate sites unknowingly loading malicious ads as well — using Safari browser could have let remote attackers secretly access your device's camera, microphone, or location, and in some cases, saved passwords as well. Apple recently paid a $75,000 bounty reward to an ethical hacker, Ryan Pickren , who practically demonstrated the hack and helped the company patch a total of seven new vulnerabilities before any real attacker could take advantage of them. The fixes were issued in a series of updates to Safari spanning versions 13.0.5 (released January 28, 2020) and Safari 13.1 (published March 24, 2020). "If the malicious website wanted camera access, all it had to do was masquerade as a trusted video-conferencing website such as Skype or Zoom," Pickren said. When chained together, three of the reported Safari...
