Google has released security updates to address a vulnerability in its Chrome browser for which an exploit exists in the wild. The zero-day vulnerability, tracked as CVE-2025-6554 (CVSS score: N/A), has been described as a type confusing flaw in the V8 JavaScript and WebAssembly engine. "Type confusion in V8 in Google Chrome prior to 138.0.7204.96 allowed a remote attacker to perform arbitrary

Orkes Conductor v3.21.11 allows remote attackers to execute arbitrary OS commands through unrestricted access to Java classes.

In Akka through 2.10.6, akka-cluster-metrics uses Java serialization for cluster metrics.

### Summary Arbitrary HTML can be inserted into the DOM by inserting a payload into any allowed attribute of the `<tabber>` tag. ### Details The `args` provided within the wikitext as attributes to the `<tabber>` tag are passed to the TabberComponentTabs class: https://github.com/StarCitizenTools/mediawiki-extensions-TabberNeue/blob/3a23b703ce36cfc4128e7921841f68230be4059a/includes/Tabber.php#L76 In TabberComponentTabs, the attributes are validated before being supplied to the Tabs template. https://github.com/StarCitizenTools/mediawiki-extensions-TabberNeue/blob/3a23b703ce36cfc4128e7921841f68230be4059a/includes/Components/TabberComponentTabs.php#L15-L31 However, the validation is insufficient. What `Sanitizer::validateTagAttributes` does is call `validateAttributes`, which ``` * - Discards attributes not on the given list * - Unsafe style attributes are discarded * - Invalid id attributes are re-encoded ``` However, the attribute values are expected to be escaped when inserte...

## Summary ## The Markdown preview function of File Browser v2.32.0 is vulnerable to *Stored Cross-Site-Scripting (XSS)*. Any JavaScript code that is part of a Markdown file uploaded by a user will be executed by the browser ## Impact ## A user can upload a malicious Markdown file to the application which can contain arbitrary HTML code. If another user within the same scope clicks on that file, a rendered preview is opened. JavaScript code that has been included will be executed. Malicious actions that are possible include: * Obtaining a user's session token * Elevating the attacker's privileges, if the victim is an administrator (e.g., gaining command execution rights) ## Vulnerability Description ## Most Markdown parsers accept arbitrary HTML in a document and try rendering it accordingly. For instance, if one creates a file called `xss.md` with the following content: ```markdown # Hallo <b>foo</b> <img src="xx" onerror=alert(9)> <i>bar</i> ``` Bold and italic text ...

### Summary A stored XSS is present in Gogs which allows client-side Javascript code execution. ### Details Gogs Version: ``` docker images REPOSITORY TAG IMAGE ID CREATED SIZE gogs/gogs latest fe92583bc4fe 10 hours ago 99.3MB ``` Application version: `0.14.0+dev` Local setup using: ```bash # Pull image from Docker Hub. docker pull gogs/gogs # Create local directory for volume. sudo mkdir -p /var/gogs # Use `docker run` for the first time. docker run --name=gogs -p 10022:22 -p 10880:3000 -v /var/gogs:/data gogs/gogs ``` The vulnerability is caused by the usage of a vulnerable and outdated component: `pdfjs-1.4.20` under public/plugins/.

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** To succesfully exploit this vulnerability, an attacker would need existing ability to execute Javascript in the impacted process.

### Summary A critical XML External Entity (XXE) vulnerability exists in the xunit-xml-plugin used by Allure 2. The plugin fails to securely configure the XML parser (`DocumentBuilderFactory`) and allows external entity expansion when processing test result .xml files. This allows attackers to read arbitrary files from the file system and potentially trigger server-side request forgery (SSRF). ### Details In `\allure2-main\plugins\xunit-xml-plugin\src\main\java\io\qameta\allure\xunitxml\XunitXmlPlugin.java` the application uses `DocumentBuilderFactory` without disabling DTDs or external entities. By generating a report with a malicious xml file within it, an attacker can perform XXE to leverage SSRF, or to read system files. ### PoC To recreate this vulnerability, you need to install allure for command-line (In my POC I used a Windows 11 Machine). 1. Create a folder called `allure`, and within it, create a malicious XML file. I will attach my SSRF and file reading payloads, however...

Cybersecurity researchers have detailed two now-patched security flaws in SAP Graphical User Interface (GUI) for Windows and Java that, if successfully exploited, could have enabled attackers to access sensitive information under certain conditions. The vulnerabilities, tracked as CVE-2025-0055 and CVE-2025-0056 (CVSS scores: 6.0), were patched by SAP as part of its monthly updates for January

Cybersecurity researchers have uncovered a fresh batch of malicious npm packages linked to the ongoing Contagious Interview operation originating from North Korea. According to Socket, the ongoing supply chain attack involves 35 malicious packages that were uploaded from 24 npm accounts. These packages have been collectively downloaded over 4,000 times. The complete list of the JavaScript
