Our research team has released h3fuzz:
a fork of ffuf with HTTP/3 support and a web UI for content discovery, based on PortSwigger's Turbo Intruder research.
It reaches 120k requests per second on local benchmarks, and we cover why that rarely holds up against real targets.
You can read more here:

New research from our team: we chained an unauthenticated bulk import, an XXE buried in a nested dependency and leaked IMS credentials into full pre-auth RCE on Adobe Experience Manager Cloud.
We also cover how AI models helped (and didn't) during the audit.

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:

We are beyond giddy to be releasing tturl, the HTTP/2 CLI for finding tiny timing differences and winning request races. Our Director of Research @justinsteven can't wait to tell you all about it at @BSidesCbr today, 3:15PM on the main stage 😎

Seems that wp2shell PoCs are now floating around the internet, so we've published our blog post including our research methodology for finding the bug as well as a deep dive into the chain itself - slcyber.io/research-center/e…
Our research team discovered a critical pre-authentication RCE inside ServiceNow by bypassing their scripting sandbox (CVE-2026-6875). You can read more here: slcyber.io/research-center/s…
Our security research team discovered a pre-authentication arbitrary file read as root in cPanel (CVE-2026-29205) — a path traversal in cpdavd that we made exploitable by abusing Dovecot's + alias handling to create attacker-controlled directory names on disk.
We've updated cpanel2shell-scanner to cover both issues. Writeup and tool in replies.

Our team discovered a vulnerability in Salesforce Marketing Cloud that allowed us to leak PII of subscribers and emails sent through SFMC, without any auth. Assigned CVE-2026-22585, CVE-2026-22586, CVE-2026-22582, CVE-2026-22583, CVE-2026-2298. Read our writeup here: slcyber.io/research-center/g…
We've released a high fidelity detection technique for CVE-2026-41940 (cPanel/WHM auth bypass). You can find the research post here: slcyber.io/research-center/h… and the tool here: github.com/assetnote/cpanel2… All other scanners and detection mechanisms so far will lead to false negatives.
Our team reverse engineered the Magento PolyShell pre-auth RCE - actively exploited in the wild. No auth needed to land a PHP webshell. RCE depends on server config, but the file persists regardless. Props to @sansecio for the heads up. slcyber.io/research-center/m… @SLCyberSec

Reverse engineering large enterprise apps means wading through hundreds of vendor dependencies. We got tired of it, so we built Hyoketsu to fix it - open source, with a pre-calculated 13GB NuGet + Maven hash database.

Our security research team created a high fidelity check for the Next.js/RSC RCE (CVE-2025-55182 & CVE-2025-66478). Read more on our blog here: slcyber.io/research-center/h…
Our Security Research team discovered a critical vulnerability in Oracle Identity Manager, that leads to RCE without authentication. A patch was released 30 days ago by Oracle (CVE-2025-61757), and we highly recommend applying it. Our research post here: slcyber.io/research-center/b…
Our Security Researcher @softpoison_ published his first research post, reverse engineering CVE-2025-54236 (SessionReaper) - a critical unauthenticated RCE in Magento. From understanding @Blaklis_'s original discovery, we wrote up our analysis here: slcyber.io/assetnote-securit…
Our Security Research team presented on Finding Critical Vulnerabilities in Adobe Experience Manager at @BSidesCbr late last month. We’ve published our research detailing the internals of AEM and how we discovered seven CVEs ranging in criticality here: slcyber.io/assetnote-securit….
Earlier this year, our Security Research team discovered a high-risk secondary context path traversal issue in Omnissa Workspace One UEM (CVE-2025-25231). We also developed a chain to RCE on instances in the wild. You can read our detailed research here: slcyber.io/assetnote-securit…
