They grow up so fast, happy eighteen nginx RCE 🥹
⚡ An 18-year-old flaw in NGINX can let unauthenticated attackers run code or crash servers using crafted HTTP requests. Tracked as CVE-2026-42945 and named NGINX Rift, the bug affects NGINX Plus and Open Source. Patch details and mitigation steps: thehackernews.com/2026/05/18-yea…
Hacking with AI is quite boring and I confess that I missed some fun of hacking recently, but building things with AI is incredible fun I feel that I have never learned so much about Software Engineering/Architecture before, even without writing a single line of code
this is me in a few days ago
btw, some of these vulnerabilities stemmed from specific research into React Native apps. Uncovered some interesting techniques to escalate impact by abusing common mistakes in hybrid app implementations. Full technical writeup once the disclosure window closes.

@eeyitemi a lot of collisions and pretty sick bugs :)
everyone, i need your help, anyone can hook us up with the "ESXi version 9.1.0.0"? your RT is really appreciated, this is Urgent AF.
Because we train LLMs on lots of movies and books about AI uprising, or articles and tweets about dystopian fears of AI, we might be causing the threat ourselves 🤔
Our second blog post is out here: bugscale.ch/blog/here-we-g… ! We managed to install arbitrary APKs on the Samsung Galaxy S25 from an app without install permissions. For this, @SachaKozma did most of the work, but it was great looking into Samsung's cloud gaming component with him
do it :)

@ProtonDrive @bigitelif0 apple? started wrong....
I am talking about mobile... AI can speed up / help with BB (reports, PoCs).... but for finding real vulns, it’s mostly low-hanging fruit so far. So...don’t abandon a target just because Claude says so :)
There are no words.
