The browser has become the main interface to GenAI for most enterprises: from web-based LLMs and copilots, to GenAI‑powered extensions and agentic browsers like ChatGPT Atlas. Employees are leveraging the power of GenAI to draft emails, summarize documents, work on code, and analyze data, often by copying/pasting sensitive information directly into prompts or uploading files.

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 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

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.
The vulnerability in question is CVE-2025-58360 (CVSS score: 8.2), an unauthenticated XML External Entity (XXE) flaw that affects all versions prior to

This week’s cyber stories show how fast the online world can turn risky. Hackers are sneaking malware into movie downloads, browser add-ons, and even software updates people trust. Tech giants and governments are racing to plug new holes while arguing over privacy and control. And researchers keep uncovering just how much of our digital life is still wide open.

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

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

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.

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

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
