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...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has urged federal agencies to patch the recent React2Shell vulnerability by December 12, 2025, amid reports of widespread exploitation. The critical vulnerability, tracked as CVE-2025-55182 (CVSS score: 10.0), affects the React Server Components (RSC) Flight protocol. The underlying cause of the issue is an unsafe deserialization that allows an attacker to inject malicious logic that the server executes in a privileged context. It also affects other frameworks, including Next.js, Waku, Vite, React Router, and RedwoodSDK. "A single, specially crafted HTTP request is sufficient; there is no authentication requirement, user interaction, or elevated permissions involved," Cloudforce One, Cloudflare's threat intelligence team, said . "Once successful, the attacker can execute arbitrary, privileged JavaScript on the affected server." Since its public disclosure on December 3, 2025, the shortcoming...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added a high-severity security flaw impacting OSGeo GeoServer to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation in the wild.

Cybersecurity researchers have disclosed details of a new fully-featured Windows backdoor called NANOREMOTE that uses the Google Drive API for command-and-control (C2) purposes. According to a report from Elastic Security Labs, the malware shares code similarities with another implant codenamed FINALDRAFT (aka Squidoor) that employs Microsoft Graph API for C2. FINALDRAFT is attributed to a threat cluster known as REF7707 (aka CL-STA-0049, Earth Alux, and Jewelbug). "One of the malware's primary features is centered around shipping data back and forth from the victim endpoint using the Google Drive API," Daniel Stepanic, principal security researcher at Elastic Security Labs, said. "This feature ends up providing a channel for data theft and payload staging that is difficult for detection. The malware includes a task management system used for file transfer capabilities that include queuing download/upload tasks, pausing/resuming file transfers, canceling file...

As enterprises refine their strategies for handling Non-Human Identities (NHIs), Robotic Process Automation (RPA) has become a powerful tool for streamlining operations and enhancing security. However, since RPA bots have varying levels of access to sensitive information, enterprises must be prepared to mitigate a variety of challenges. In large organizations, bots are starting to outnumber human employees, and without proper identity lifecycle management, these bots increase security risks. RPA impacts Identity and Access Management (IAM) by managing bot identities, enforcing least-privilege access and ensuring auditability across all accounts. Continue reading to learn more about RPA, its challenges with IAM and best practices organizations should follow to secure RPA within IAM. What is Robotic Process Automation (RPA)? Robotic Process Automation (RPA) uses bots to automate repetitive tasks that are traditionally performed by human users. In the context of IAM, RPA plays an ess...

An advanced persistent threat (APT) known as WIRTE has been attributed to attacks targeting government and diplomatic entities across the Middle East with a previously undocumented malware suite dubbed AshTag since 2020 . Palo Alto Networks Unit 42 is tracking the activity cluster under the name Ashen Lepus . Artifacts uploaded to the VirusTotal platform show that the threat actor has trained its sights on Oman and Morocco, indicating an expansion in operational scope beyond the Palestinian Authority, Jordan, Iraq, Saudi Arabia, and Egypt. The company told The Hacker News said it has observed "scores of unique lures" disseminated across the Middle East, indicating a "persistent and wide-reaching campaign" confined to government and diplomatic entities in the region. More than a dozen entities are estimated to have been targeted, although it's suspected that the real number could be higher. "Ashen Lepus remained persistently active throughout the Israel...

A high-severity unpatched security vulnerability in Gogs has come under active exploitation, with more than 700 compromised instances accessible over the internet, according to new findings from Wiz. The flaw, tracked as CVE-2025-8110 (CVSS score: 8.7), is a case of file overwrite in the file update API of the Go-based self-hosted Git service. A fix for the issue is said to be currently in the works. The company said it accidentally discovered the zero-day flaw in July 2025 while investigating a malware infection on a customer's machine. "Improper symbolic link handling in the PutContents API in Gogs allows local execution of code," according to a description of the vulnerability in CVE.org. The cloud security company said CVE-2025-8110 is a bypass for a previously patched remote code execution flaw ( CVE-2024-55947 , CVSS score: 8.7) that allows an attacker to write a file to an arbitrary path on the server and gain SSH access to the server. CVE-2024-55947 was add...

Google on Wednesday shipped security updates for its Chrome browser to address three security flaws, including one it said has come under active exploitation in the wild. The vulnerability, rated high in severity, is being tracked under the Chromium issue tracker ID " 466192044 ." Unlike other disclosures, Google has opted to keep information about the CVE identifier, the affected component, and the nature of the flaw under wraps. However, a GitHub commit for the Chromium bug ID has revealed that the issue resides in Google's open-source Almost Native Graphics Layer Engine ( ANGLE ) library, with the commit message stating "Metal: Don't use pixelsDepthPitch to size buffers. pixelsDepthPitch is based on GL_UNPACK_IMAGE_HEIGHT, which can be smaller than the image height." This indicates the problem is likely a buffer overflow vulnerability in ANGLE's Metal renderer triggered by improper buffer sizing, which could lead to memory corruption, program cra...

Huntress is warning of a new actively exploited vulnerability in Gladinet's CentreStack and Triofox products stemming from the use of hard-coded cryptographic keys that have affected nine organizations so far. "Threat actors can potentially abuse this as a way to access the web.config file, opening the door for deserialization and remote code execution," security researcher Bryan Masters said . The use of hard-coded cryptographic keys could allow threat actors to decrypt or forge access tickets, enabling them to access sensitive files like web.config that can be exploited to achieve ViewState deserialization and remote code execution, the cybersecurity company added. The vulnerability has not been assigned a CVE identifier. At its core, the issue is rooted in a function named "GenerateSecKey()" present in "GladCtrl64.dll" that's used to generate the cryptographic keys necessary to encrypt access tickets containing authorization data (i.e., User...

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...

New research has uncovered exploitation primitives in the .NET Framework that could be leveraged against enterprise-grade applications to achieve remote code execution. WatchTowr Labs, which has codenamed the "invalid cast vulnerability" SOAPwn , said the issue impacts Barracuda Service Center RMM, Ivanti Endpoint Manager (EPM), and Umbraco 8. But the number of affected vendors is likely to be longer given the widespread use of .NET. The findings were presented today by watchTowr security researcher Piotr Bazydlo at the Black Hat Europe security conference, which is being held in London. SOAPwn essentially allows attackers to abuse Web Services Description Language (WSDL) imports and HTTP client proxies to execute arbitrary code in products built on the foundations of .NET due to errors in the way they handle Simple Object Access Protocol ( SOAP ) messages. "It is usually abusable through SOAP clients, especially if they are dynamically created from the attacker-c...

Three security vulnerabilities have been disclosed in the Peripheral Component Interconnect Express (PCIe) Integrity and Data Encryption ( IDE ) protocol specification that could expose a local attacker to serious risks. The flaws impact PCIe Base Specification Revision 5.0 and onwards in the protocol mechanism introduced by the IDE Engineering Change Notice (ECN), according to the PCI Special Interest Group ( PCI-SIG ). "This could potentially result in security exposure, including but not limited to, one or more of the following with the affected PCIe component(s), depending on the implementation: (i) information disclosure, (ii) escalation of privilege, or (iii) denial of service," the consortium noted . PCIe is a widely used high-speed standard to connect hardware peripherals and components, including graphics cards, sound cards, Wi-Fi and Ethernet adapters, and storage devices, inside computers and servers. Introduced in PCIe 6.0, PCIe IDE is designed to secure data ...
