LikeC4 uses React and Next.js: which contain known RCE vulnerabilities, as seen in CVE-2025-55182. [2025-12-15] Edit: the last fixes published by React were not thorough, a new set of fix releases completes the mitigation; see https://react.dev/blog/2025/12/11/denial-of-service-and-source-code-exposure-in-react-server-components

If you use a smartphone, browse the web, or unzip files on your computer, you are in the crosshairs this week. Hackers are currently exploiting critical flaws in the daily software we all rely on—and in some cases, they started attacking before a fix was even ready. Below, we list the urgent updates you need to install right now to stop these active threats. ⚡ Threat of the Week Apple and

The pro-Russian hacktivist group known as CyberVolk (aka GLORIAMIST) has resurfaced with a new ransomware-as-a-service (RaaS) offering called VolkLocker that suffers from implementation lapses in test artifacts, allowing users to decrypt files without paying an extortion fee. According to SentinelOne, VolkLocker (aka CyberVolk 2.x) emerged in August 2025 and is capable of targeting both Windows

The Preset configuration feature of Vuetify is vulnerable to Prototype Pollution due to the internal 'mergeDeep' utility function used to merge options with defaults. Using a specially-crafted, malicious preset can result in polluting all JavaScript objects with arbitrary properties, which can further negatively affect all aspects of the application's behavior. This can lead to a wide range of security issues, including resource exhaustion/denial of service or unauthorized access to data. If the application utilizes Server-Side Rendering (SSR), this vulnerability could affect the whole server process. This issue affects Vuetify versions greater than or equal to 2.2.0-beta.2 and less than 3.0.0-alpha.10. Note: Version 2.x of Vuetify is End-of-Life and will not receive any updates to address this issue. For more information see here https://v2.vuetifyjs.com/en/about/eol/ .

It was found that the fix addressing [CVE-2025-55184](https://github.com/advisories/GHSA-2m3v-v2m8-q956) in React Server Components was incomplete and did not fully prevent denial-of-service attacks in all payload types. This affects React package versions 19.0.2, 19.1.3, and 19.2.2 and frameworks that use the affected packages, including Next.js 13.x, 14.x, 15.x and 16.x using the App Router. The issue is tracked upstream as [CVE-2025-67779](https://www.cve.org/CVERecord?id=CVE-2025-67779). A malicious HTTP request can be crafted and sent to any Server Function endpoint that, when deserialized, can enter an infinite loop within the React Server Components runtime. This can cause the server process to hang and consume CPU, resulting in denial of service in unpatched environments.

### Impact `@vitejs/plugin-rsc` vendors `react-server-dom-webpack`, which contained a vulnerability in versions prior to 19.2.3. See details in React repository's advisory https://github.com/facebook/react/security/advisories/GHSA-7gmr-mq3h-m5h9 ### Patches Upgrade immediately to `@vitejs/plugin-rsc@0.5.7` or later.

## Impact It was found that the fix to address [CVE-2025-55184](https://github.com/facebook/react/security/advisories/GHSA-2m3v-v2m8-q956) in React Server Components was incomplete and does not prevent a denial of service attack in a specific case. We recommend updating immediately. The vulnerability exists in versions 19.0.2, 19.1.3, and 19.2.2 of: - [react-server-dom-webpack](https://www.npmjs.com/package/react-server-dom-webpack) - [react-server-dom-parcel](https://www.npmjs.com/package/react-server-dom-parcel) - [react-server-dom-turbopack](https://www.npmjs.com/package/react-server-dom-turbopack?activeTab=readme) These issues are present in the patches published on December 11th, 2025. ## Patches Fixes were back ported to versions 19.0.3, 19.1.4, and 19.2.3. If you are using any of the above packages please upgrade to any of the fixed versions immediately. If your app’s React code does not use a server, your app is not affected by this vulnerability. If your app does not...

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) 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
