The Brotli RCE in Node.js is brutal! CVE-2026-111497 affects all three supported major lines: 22.0.0-22.23.3, 24.0.0-24.22.0, and 26.0.0-26.12.0. One sleepless night with GLM-5.3 and DeepSeek V4.1 Flash 1017, plus $26.80 in tokens, and I had a reliable PoC across those versions on Linux arm64 and x86_64 with ASLR and UV_THREADPOOL_SIZE independent vectors for all 84 builds. But I wouldn't call it suitable for blind black-box testing. I ran 14,877 fresh exploit attempts - every ARM target against every ARM and x86 profile, each in a fresh lab. Wrong profiles are destructive: 58.3% crashed the lab (56.4% ARM profiles, 60.2% x86 profiles replayed on ARM). And HTTP-only fingerprinting was useless: all 87 builds returned byte-identical responses, so you cannot safely guess the profile without force/out-of-band info. Bug bounty hunters, please do not spray profiles at production :) Nine years ago, when I started my career as a Node.js SWE, I never imagined that an ordinary body-parser setup on a Node.js runtime could become an RCE entry point. 2026 keeps surprising me. And it's making me look at attack surfaces differently... Huge respect to the researchers who found this bug

UPDATE: Israeli company we caught delivering zero-click infections is #1 bidder on Starlink ads in 105 countries. Data from @trendai_RSRCH suggests worldwide surveillance op targeting @Starlink users. 1/ By @razhael reuters.com/business/media-t…
🚨NEW INVESTIGATION: zero-click mercenary spyware hacking via targeted ads. A normal-looking ad loads. If you're a target, you're infected. No click needed. To protect yourself, block ads now. First time it's been confirmed in the wild. We call it #AdFection. Candiru spyware infections at @AJEnglish. 45+ devices infected. Same ad pipeline operated by Israeli company Discover-Tech reached NATO, European Parliament, dozens of gov networks & critical infrastructure incl US nuclear giant Westinghouse. Confiant, which worked with us, found signs ads were displayed at US @DeptofWar, IAEA & ICC.

Announcing 3 Critical vulns for hundreds of millions of IoT, Firewalls, OT, and Military devices including: Palo Alto Networks, Comcast, D-Link, HP, Canon, Honeywell, GE, Oracle, Siemens, Rockwell, Digi, Lockheed Martin, Boeing... The vulns are with GoAhead Web Server which is a backend library used by these devices. There's a patch available from GoAhead but that doesn't mean there's a patch available for the devices yet -- that's up to the manufacturer. - TLS traffic over DHE ciphers have a 1-byte secret, "04", meaning anyone can decrypt connections to these devices and steal login credentials and session tokens if the client negotiated with DHE ciphers like the latest TLS_DHE_RSA_WITH_CHACHA20_POLY1305_SHA256, which is extremely likely. - LibreSSL mTLS has been completely bypassed, meaning anyone can connect over mTLS. If you have one of these devices listening on the internet and are expecting mTLS to protect it from attackers, take it offline or patch asap. - OpenSSL Certificate Revocation Lists (CRLs) are not enforced, meaning if a user device is stolen or compromised, and you revoke that mTLS cert, nothing actually happens. There are a lot of other attacks this can be used for. These are critical because these types of devices run our world. Water systems, electricity, military, firewalls, critical infrastructure. foxio.io/blog/choose-your-ba…

Our demo shows PHP2Shell giving a shell on MediaWiki, Symfony, Laravel, and phpBB. We’ve confirmed exploits work on pre-patch releases of PHP 8.2–8.5. If you haven’t updated, assume attackers can compromise your server, and that exploitation will only get easier.
Update: Our PHP exploit is now production-grade. * stock php.ini-production, display_errors=off, normal memory_limit, multi-worker, ASLR, under load * ARM64 + x86-64 targets * MediaWiki, WordPress, phpBB, Laravel * Apache/mod_php and nginx/php-fpm -> root

KillaBoi ha publicado un exploit de PHP2Shell que, según dice, consigue ejecución remota de código con ASLR activado. github.com/KillaBoi/StealMyB… El desarrollo está relacionado con un desafío público de seguridad resuelto el 25 de octubre a las 15:47 UTC, por el que recibió aproximadamente 2.000 dólares en Bitcoin. La diferencia respecto a los PoC anteriores es que ahora existe código público acompañado de una explicación técnica detallada y resultados de laboratorio reproducibles. Lo que ha probado: - Agotamiento de memoria durante el procesamiento de peticiones multipart. - Divulgación de direcciones del heap mediante cookies de sesión. - Divulgación de una dirección de código PHP para superar ASLR. - Construcción de una estructura interna falsa que provoca una llamada a la función PHP system(). Pero, la imagen Docker utilizada, aunque llevaba la etiqueta php:8.4.26-fpm-alpine3.23, se ejecutó con php -S, no PHP-FPM, por tanto no es reproducible en Apache + PHP-FPM. El propio KillaBoi dice que los desplazamientos de memoria usados dependen de la compilación y que el exploit no funciona directamente contra una imagen Debian PHP-FPM con la misma versión de PHP. A pesar de la mejora de su PoC, es una pequeña trampa, porque sigue sin demostrar que se pueda atacar exitosamente un PHP-FPM Este, como explicaba ayer, es el desafío que falta para que PHP2Shell acabe siendo un problema de dimensiones apocalípticas. Seguimos vigilantes.
