## Impact Applications meeting these two conditions are at risk of arbitrary JavaScript code execution, even if "safe mode" [expressionInterpreter](https://vega.github.io/vega/usage/interpreter/) is used. 1. Use `vega` in an application that attaches both `vega` library and a `vega.View` instance similar to the Vega [Editor](https://github.com/vega/editor) to the global `window`, or has any other satisfactory function gadgets in the global scope 2. Allow user-defined Vega `JSON` definitions (vs JSON that was is only provided through source code) ## Patches - With Vega v6, use `vega-selections@6.1.2` (requires ESM) - With Vega v5, use `vega-selections@5.6.3` (No ESM needed) ## Workarounds - Do not attach `vega` or `vega.View` instances to global variables or the window as the editor used to do [here](https://github.com/vega/editor/blob/e102355589d23cdd0dbfd607a2cc5f9c5b7a4c55/src/components/renderer/renderer.tsx#L239) . This is a development-only debugging practice that should n...

Security experts at Zenity Labs warn that Anthropic’s new agentic browser extension, Claude in Chrome, could bypass traditional web security, exposing private data and login tokens to potential hijackers.

Improper Restriction of XML External Entity Reference vulnerability in Apache SIS. It is possible to write XML files in such a way that, when parsed by Apache SIS, an XML file reveals to the attacker the content of a local file on the server running Apache SIS. This vulnerability impacts the following SIS services: * Reading of GeoTIFF files having the GEO_METADATA tag defined by the Defense Geospatial Information Working Group (DGIWG). * Parsing of ISO 19115 metadata in XML format. * Parsing of Coordinate Reference Systems defined in the GML format. * Parsing of files in GPS Exchange Format (GPX). This issue affects Apache SIS from versions 0.4 through 1.5 inclusive. Users are recommended to upgrade to version 1.6, which will fix the issue. In the meantime, the security vulnerability can be avoided by launching Java with the javax.xml.accessExternalDTD system property sets to a comma-separated list of authorized protocols. For example: java -Djavax.xml.ac...

### Summary Affected Components: ``` org.msgpack.core.MessageUnpacker.readPayload() org.msgpack.core.MessageUnpacker.unpackValue() org.msgpack.value.ExtensionValue.getData() ``` A denial-of-service vulnerability exists in MessagePack for Java when deserializing .msgpack files containing EXT32 objects with attacker-controlled payload lengths. While MessagePack-Java parses extension headers lazily, it later trusts the declared EXT payload length when materializing the extension data. When ExtensionValue.getData() is invoked, the library attempts to allocate a byte array of the declared length without enforcing any upper bound. A malicious .msgpack file of only a few bytes can therefore trigger unbounded heap allocation, resulting in JVM heap exhaustion, process termination, or service unavailability. This vulnerability is triggered during model loading / deserialization, making it a model format vulnerability suitable for remote exploitation. ### PoC ``` import msgpack import struct imp...

The year opened without a reset. The same pressure carried over, and in some places it tightened. Systems people assume are boring or stable are showing up in the wrong places. Attacks moved quietly, reused familiar paths, and kept working longer than anyone wants to admit. This week’s stories share one pattern. Nothing flashy. No single moment. Just steady abuse of trust — updates, extensions,

Action captions in Vaadin accept HTML by default but were not sanitized, potentially allowing Cross-site Scripting (XSS) if caption content is derived from user input. In Vaadin Framework 7 and 8, the Action class is a general-purpose class that may be used by multiple components. The fixed versions sanitize captions by default and provide an API to explicitly enable HTML content mode for backwards compatibility. In Vaadin 23 and newer, the Action class is only used by the Spreadsheet component. The fixed versions sanitize HTML using Jsoup with a relaxed safelist. Vaadin 14 is not affected as Spreadsheet component was not supported. Users of affected versions should apply the following mitigation or upgrade. Releases that have fixed this issue include: Product version Vaadin 7.0.0 - 7.7.49 Vaadin 8.0.0 - 8.29.1 Vaadin 23.1.0 - 23.6.5 Vaadin 24.0.0 - 24.8.13 Vaadin 24.9.0 - 24.9.6 Mitigation Upgrade to 7.7.50 Upgrade to 8.30.0 Upgrade to 23.6.6 Upgrade to 24.8.14 or 24.9.7 Upgrade...

Cybersecurity researchers have disclosed details of a new Python-based information stealer called VVS Stealer (also styled as VVS $tealer) that's capable of harvesting Discord credentials and tokens. The stealer is said to have been on sale on Telegram as far back as April 2025, according to a report from Palo Alto Networks Unit 42. "VVS stealer's code is obfuscated by Pyarmor," researchers

## Security Advisory: Stored XSS Leading to Admin Account Takeover **Affected Versions:** ≤ 5.1.0 **Vulnerability Type:** CWE-79: Stored Cross-Site Scripting --- ## Summary A lower-privileged user with campaign management permissions can inject malicious JavaScript into campaigns or templates. When a higher-privileged user (Super Admin) views or previews this content, the XSS executes in their browser context, allowing the attacker to perform privileged actions such as creating backdoor admin accounts. The attack can be weaponized via the **public archive feature**, where victims simply need to visit a link - no preview click required. --- ## Required Attacker Permissions ``` campaigns:manage - Create/edit campaigns campaigns:get - View campaigns lists:get_all - Access lists templates:get - Access templates ``` **Note:** These are common permissions for content managers who are not full admins. --- ## Attack Vectors ### Vector 1: Raw HTML (Direct ...

### Summary A stored Cross-Site Scripting (XSS) vulnerability exists in Bagisto 2.3.8 within the CMS page editor. Although the platform normally attempts to sanitize `<script>` tags, the filtering can be bypassed by manipulating the raw HTTP POST request before submission. As a result, arbitrary JavaScript can be stored in the CMS content and executed whenever the page is viewed or edited. This exposes administrators to a high-severity risk, including complete account takeover, backend hijacking, and malicious script execution. ### Details Bagisto’s CMS editor includes an HTML sanitation mechanism intended to protect against script injection by wrapping raw script content in `<div>` elements. However, this mechanism is applied only to requests submitted through the UI. When the CMS update request is intercepted and modified at the HTTP level, the sanitation layer fails to strip or encode embedded `<script>` tags. Because the back-end trusts the manipulated request, the malicious scri...

SignalK Server exposes two features that can be chained together to steal JWT authentication tokens without any prior authentication. The attack combines WebSocket-based request enumeration with unauthenticated polling of access request status. **Unauthenticated WebSocket Request Enumeration**: When a WebSocket client connects to the SignalK stream endpoint with the `serverevents=all` query parameter, the server sends all cached server events including `ACCESS_REQUEST` events that contain details about pending access requests. The `startServerEvents` function iterates over `app.lastServerEvents` and writes each cached event to any connected client without verifying authorization level. Since WebSocket connections are allowed for readonly users (which includes unauthenticated users when `allow_readonly` is true), attackers receive these events containing request IDs, client identifiers, descriptions, requested permissions, and IP addresses. **Unauthenticated Token Polling**: The acces...
