Today, Wiz (Woogle?) released an advisory detailing an attack chain they’ve dubbed IngressNightmare, which, if left exposed and unpatched, can be exploited to achieve remote code execution by unauthenticated attackers. The advisory, covering five separate vulnerabilities, was published after a brief embargo period, once the Kubernetes folks got their patches together.

The researchers who found the Next.js middleware vulnerability (CVE-2025-29927) have released the full paper: https://zhero-web-sec.github.io/research-and-things/nextjs-and-the-corrupt-middleware
Notable is that the auth bypass requires the x-middleware-subrequest value to be one of these two forms:
middleware:middleware:middleware:middleware:middleware OR
src/middleware:src/middleware:src/middleware:src/middleware:src/middleware
Next.js dropped a CVSS 9.1 authentication bypass vulnerability (CVE-2025-29927) over the weekend. This flaw is trivially exploitable by sending the header `x-middleware-subrequest: true` and causes the request to skip all middleware processing, including any authentication steps.
Shodan reports over 300,000 services with the `X-Powered-By: Next.js` header alone.

Good morning from Bootstrap`25[1] in Austin, Texas! Haroon Meer kicks us off with "Security Products Don't Have To Suck", which makes many great points, but among those that most security industry "awards" are hot garbage play-to-win trophies, run by the same marketing agencies under a dozen aliases (but often the same Google Analytics ID):

The worst part of the Unciphered story isn't that accused-rapist Morgan Marquis-Boire was a co-founder and only his alias "Frank Davidson" was known to employees; it is that Eric Michaud co-founded the company with him and conspired to keep the team from knowing about it. Infosec has its pariahs for a reason (Cap'n Crunch, Jacob Applebaum, Morgan Marquis-Boire, and to a lesser degree Christopher Hadnagy): https://archive.ph/IQ7SK
The Tarlogic claim of backdoor functions in the ESP32 Bluetooth firmware seems overblown. The features they identified require privileged code execution and are helpful for improving open source software for these devices.

It doesn't look like Chris Hadnagy's lawsuit against DEF CON is going well: https://www.reddit.com/r/Defcon/comments/1ivo7x0/hadnagy_vs_defcon_et_al_motion_for_summary
>Hadnagy complains that Def Con’s statements harmed his reputation. But a person earns their reputation, good or bad, through their actions.
