[RSS] Critical RCE Vulnerability CVE-2025-11953 Puts React Native Developers at Risk

"The Metro development server [..] binds to external interfaces by default [...] The server%27s /open-url endpoint handles a POST request that includes a user-input value that is passed to the unsafe open() function provided by the open NPM package, which will cause OS command execution."

Randomly Scheduled Reminder: You should use a tool like Loqseq or Obsidian to keep notes and a journal of your life, work, and what you're doing. Future you will thank you. Having those details handy and searchable comes in handy in so many ways.

NEW: This is how former L3Harris Trenchant boss Peter Williams was able to steal zero-days worth millions of dollars and sell them to a Russian broker, based on court documents and interviews with his former colleagues. 

A former Trenchant employee told me that “no one had any supervision over [Williams] at all. He was kind of allowed to do things the way he wanted to.”

“He was, in my opinion, perceived to be beyond reproach,” the former employee, who has knowledge of Trenchant's IT systems, told me.

I love reverse-engineering because it allows me to dismantle structures of control.

Here's an example of Google's AI reporting security vulnerabilities in this codec:

https://issuetracker.google.com/issues/440183164

We take security very seriously but at the same time is it really fair that trillion dollar corporations run AI to find security issues on people's hobby code? Then expect volunteers to fix.
https://bird.makeup/users/ffmpeg/statuses/1983949866725437791

Arguably the most brilliant engineer in FFmpeg left because of this. He reverse engineered dozens of codecs by hand as a volunteer.

Then security "researchers" and corporate employees came along repeatedly insisted "critical" security issues were fixed immediately waving their CVEs.

This was hugely demotivating to the fun and enjoyment of reverse engineering.

An out-of-band (OOB) security update that patches an actively exploited Windows Server Update Service (WSUS) vulnerability has broken hotpatching on some Windows Server 2025 devices.

This week on #OpenSourceSecurity I talk to @ottok about his blog post about detecting an attack like xz in Debian

It's a fascinating conversation about a very complicated topic

There are things that could be detected, but this one would have been very very difficult

This year Binarly has also expanded their sponsorship to the creation of a new Firmware Security Learning Path! https://ost2.fyi/OST2_LP_FWSEC.pdf

This captures current and future plans for classes involving security in the deep-dark of firmware! But Binarly is starting to give visibility into what's going on there with their binary analysis platform.

It is decided, the final round of #BSidesVienna tickets will be in 7 days from now on Sunday 09.11.2025 at 7 pm. That is 19:00 o'clock Vienna time UTC+1!
