Please be sure you don’t take your eye off the big node.js/brotli vulnerability while php2shell was sucking all the air from the room. https://www.aikido.dev/blog/python-packages-vulnerable-node2shell-brotli-cve-2026-111497
RE: https://fosstodon.org/@keepassxc/117320648185069600
🚨Attention! Yesterday, we published new 2.8.0-1 binaries for macOS (DMG) and Linux (AppImage) to fix three separate upstream Qt bugs on macOS and to ship an updated version of Brotli that fixes CVE-2026-111497.
The new version will not show up as an update automatically, but we recommend everyone to install it from https://keepassxc.org/download/ until the release of 2.8.1.
Ubuntu still considers the #brotli RCE (CVE-2026-111497) as "medium" priority:

CVE-2026-111497 is classified as CWE-787. Can *anyone* confirm that it works with ASLR enabled, or was that *completely omitted* from all reports?

Evolving threat 🚨 CVE-2026-111497, previously known to affect Node.js (node2shell) and Python has evolved into “HTTP2Shell.”
https://www.aikido.dev/blog/python-packages-vulnerable-node2shell-brotli-cve-2026-111497
Uh oh: ⚠️ Brotli is a widely used compression library from Google. On Wednesday, October 21st NodeJS disclosed CVE-2026-111497, dubbed “node2shell,” wherein a Node.js process that decompresses attacker-controlled Brotli data can be made to leak memory or run arbitrary code. On Thursday, Python disclosed that Python packages were vulnerable to CVE-2026-111497 as well.

2/3 Also done today:
Checked the Node.js October security release (Brotli CVE-2026-111497). Our streaming server never decompresses untrusted Brotli data, so the risk is low. We'll update as soon as the FreeBSD package is out.
The streaming server now properly verifies the database's TLS certificate.
Rewrote our rc.d scripts the way rc.subr intends: supervisor pidfile, automatic restart after a crash, and "service restart" works on the first try. Background: https://blog.hofstede.it/freebsd-foundationals-rcd-the-service-framework-that-fits-in-your-head/
Package updates on the host and in all jails
nginx: separate cache directories, a nearby DNS resolver (thousands of DNS errors gone) and a catch-all for unknown hostnames
We retired our Tor onion service
Lots of small cleanups after a deep health check
CVE-2026-111497 is a memory-corruption flaw in Google’s Brotli decoder, used by software including Bun, Python Brotli and brotlicffi, Envoy, Istio, Node.js and cdxgen.
Crafted compressed data can corrupt program memory and potentially lead to code execution.
Imperva researchers demonstrated code execution on an unpatched Node.js build; similar execution has not been shown on the other affected software, and no real-world attacks have be…
Node2Shell Brotli vuln (CVE-2026-111497) evolves to HTTP2Shell, as libraries and apps using HTTP are affected.

"The public PoC's own author states it plainly: the highest verified result is bounded command execution, demonstrated only on a deliberately non-PIE, ASLR-off local harness — not a portable remote exploit."

If you are looking for detection rules for recent vulnerabilities, you can use rulezet
https://rulezet.org/vulnerability/CVE-2026-109618
It's pretty nifty.
#rulezet #opensource #opendata #cybersecurity #detectionengineering
FYI: CVE: CVE (Common Vulnerabilities and Exposures) is the public list giving each disclosed software flaw a unique ID such as CVE-2026-109618, run by MITRE since 1999. https://ppc.land/cve/ #CVE #CyberSecurity #Vulnerabilities #MITRE #SoftwareSecurity
This came up through my local ham radio group email (from ZL3TUX) so I felt it worth to spread here too:
"
FYI the Pi-Star firmware is vulnerable to the recent PHP vulnerability:
https://www.ncsc.govt.nz/alerts/cve-2026-109618-and-cve-2026-109619-affecting-php/
If you haven't already, upgrade PHP using APT in the normal Debian way then reboot. Backup first to be on the safe side: these SD cards have a hard life being mostly unshielded near the RF pin on the MMDVM hats.
$ rpi-rw
$ sudo mount -o remount,rw /boot/firmware/
$ sudo apt update
$ sudo apt dist-upgrade
I've tested the above steps using the latest image (4.3.7) on a Pi Zero here and it takes about an hour. Hopefully an official updated image will be available soon.
"
To be fair I have no idea what Pi-star is nor does, or what an MMDVM hat is. :-)
Hope that helps someone.

🚨 A crafted OpenAPI document can turn generated TypeScript clients into a code execution path; CVE-2026-108551
PoC: https://github.com/Zombie-Kaiser/CVE-2026-108551-POC
The flaw affects openapi-typescript-codegen and stems from unsafe interpolation inside Handlebars templates. An attacker who controls an OpenAPI document can inject JavaScript through values such as path keys, parameter names, server URLs, or version fields.
CVSS: 9.3 Critical
Affected: openapi-typescript-codegen ≤ 0.31.0
Impact: Arbitrary JavaScript execution when generated clients are imported or affected service methods are called
The PoC demonstrates how malicious OpenAPI input can survive client generation and execute once the generated code is used.
