### Summary In Bagisto v2.3.7, the TinyMCE image upload functionality allows an attacker with sufficient privileges (e.g. admin) to upload a crafted SVG file containing embedded JavaScript. When viewed, the malicious code executes in the context of the admin/user’s browser. ### Details The underlying problem is that SVG is XML/markup, so when it is uploaded and then directly rendered or embedded, script or event handlers within are allowed to run unless sanitized. In Bagisto, the integration of TinyMCE’s image upload (or media manager) may accept SVG files without sanitizing or rejecting unsafe content. When the SVG is later included (inline or via object/embed) in content displayed in admin or UI, the browser may execute the script portion of the SVG. The application might not validate the file content (i.e. inspect the SVG XML) or strip <script>, onload, onclick, foreignObject, xlink:href injection, objects/embed tags, etc. ### PoC Navigate to any forms with TinyMCE editor.

### Summary In Bagisto v2.3.7, the TinyMCE image upload functionality allows an attacker with sufficient privileges (e.g. admin) to upload a crafted HTML file containing embedded JavaScript. When viewed, the malicious code executes in the context of the admin/user’s browser. ### Details The application blocks the uploading of HTML files; however, if the backend detected that the content of the .png file is HTML or JavaScript, the file extension will be automatically converted from .png to .html. When the HTML is viewed, it will execute the JavaScript code. ### PoC Created a html file, renamed the extension to .png, and uploaded the file. It was converted to HTML file in the backend. When opened in another tab, the JavaScript code will execute. <img width="1605" height="702" alt="image" src="https://github.com/user-attachments/assets/bd9406aa-2380-464f-ac21-32d483639969" /> <img width="1358" height="314" alt="image" src="https://github.com/user-attachments/assets/e5a64a5a-39fb-4fdb-ad...

### Summary LibreNMS <= 25.8.0 contains a **Stored Cross-Site Scripting (XSS)** vulnerability in the Alert Transports management functionality. When an administrator creates a new Alert Transport, the value of the `Transport name` field is stored and later rendered in the **Transports** column of the **Alert Rules** page without proper input validation or output encoding. This leads to arbitrary JavaScript execution in the admin’s browser. ### Details * **Injection point:** `Transport name` field in `/alert-transports`. * **Execution point:** **Transports** column in `/alert-rules`. * **Scope:** Only administrators can create Alert Transports, and only administrators can view the affected Alert Rules page. Therefore, both exploitation and impact are limited to admin users. ### Steps to reproduce 1. Log in with an administrator account. 2. Navigate to: ``` http://localhost:8000/alert-transports ``` 3. Click **Create alert transport** and provide the following values: ...

A financially motivated threat actor codenamed UNC5142 has been observed abusing blockchain smart contracts as a way to facilitate the distribution of information stealers such as Atomic (AMOS), Lumma, Rhadamanthys (aka RADTHIEF), and Vidar, targeting both Windows and Apple macOS systems. "UNC5142 is characterized by its use of compromised WordPress websites and 'EtherHiding,' a technique used

Cisco Talos has uncovered a new attack linked to Famous Chollima, a threat group aligned with North Korea (DPRK).

The online world is changing fast. Every week, new scams, hacks, and tricks show how easy it’s become to turn everyday technology into a weapon. Tools made to help us work, connect, and stay safe are now being used to steal, spy, and deceive. Hackers don’t always break systems anymore — they use them. They hide inside trusted apps, copy real websites, and trick people into giving up control
