Our research team discovered two vulnerabilities in Discourse: a pre-authentication cache poisoning to sitewide XSS (CVE-2026-55674), and an arbitrary file read (RCE) chaining a JPEG race condition with ImageMagick and Ghostscript (CVE-2026-55420). You can read more here:

Recently, I've been looking at DOMPurify again, trying to find ways to bypass 3.x.x after browsers started encoding attrs during serialization.

I ended up with a nice ≤3.2.6 Safari default-configuration bypass using only SMIL tags/attrs :D

Excited to disclose my research allowing RCE in Kubernetes

It allows running arbitrary commands in EVERY pod in a cluster using a commonly granted "read only" RBAC permission. This is not logged and and allows for trivial Pod breakout.

Unfortunately, this will NOT be patched.

🚨 RCE in #Livewire (CVE-2025-54068)!

Our specialists uncovered a critical flaw allowing remote code execution without the APP_KEY, exploiting Livewire’s hydration mechanism + PHP’s loose typing.

🔗 Patch now! (v3.6.4+)

Thrilled to finally share what I’ve been building for over a year: Vulnotes👾,a reporting tool for pentesters who are tired of clunky, incomplete solutions.

Vulnotes was born from countless hours writing reports and hearing the same frustrations from friends and colleagues.

I didn’t manage to get a place for the CCC this year… I’m looking for two. If you’re selling one or know someone who is, please contact me 🙏

I'm happy to release a script gadgets wiki inspired by the work of @slekies, @kkotowicz, and @sirdarckcat in their Black Hat USA 2017 talk! 🔥

The goal is to provide quick access to gadgets that help bypass HTML sanitizers and CSPs 👇

I'm very happy to finally share the second part of my DOMPurify security research 🔥

This article mostly focuses on DOMPurify misconfigurations, especially hooks, that downgrade the sanitizer's protection (even in the latest version)!
