So basically, today PHP got two critical bugs that let anyone run code on your server without even logging in, which is bad, and then the details leaked before the patch was even out, which is worse, and it works on WordPress and MediaWiki and Magento and Joomla and Laravel, and Censys says like 1.5 million servers are running a version with no fix, so the NSA was like "take your system offline," and the FBI was like "take your system offline," and CISA and the UK and CERT-EU were all like "take your system offline," and then the Prime Minister of Japan, the actual Prime Minister, posted at 5:55 in the morning telling 48.8 million people to take their system offline, so everyone took their system offline, like the Dutch cybersecurity agency took its own website offline, and the Dutch parliament went offline, and the Port of Rotterdam went offline, and Finland and France and Denmark started pulling government sites, and Wikipedia went down, and Archive.org went down, and Asana and GOG and Something Awful went down, and the University of Vienna's webmail went down for some reason, and that's just PHP. Because GitLab also dropped a CVSS 10.0, which is the highest score they give out, for a bug that's been there since 2014, so that's every self-hosted GitLab for twelve years, and then LiteLLM 1.107.0 got hijacked and shipped a credential stealer and a remote access trojan in every single wheel and the Docker images, including latest, and you didn't even have to import it, just installing it was enough, and it's the second time this year, and then Railway paused every deployment on the entire platform because someone got into the environment variables, so now everyone has to rotate every secret they've ever stored there, and TiDB Cloud said someone was walking around inside with stolen credentials for basically a month and an extortion group says they took 10.6 terabytes, and Zeabur got breached for the second time in two months and is just shutting down, like the whole company, and Node.js patched remote code execution and a TLS bypass, and CISA says Plex is being actively exploited, and someone took over 300 Tor exit relays to steal SSH passwords, and SafePay ransomware has hit over 600 critical infrastructure orgs, and India's biggest bank filed a data loss incident, and Japan has been in an official state of emergency in cyberspace since October 9, which honestly explains the 5:55 AM post. Oh, and eMudhra, a certificate authority that's issued over 60 million certificates, whose entire job is proving websites are who they say they are, was supposed to be using private keys that are random numbers over a hundred digits long, and one of them was 4. Just 4. And the others were like 66 and 237. Anyway, it's Wednesday.

⚠️ Node.js is vulnerable to remote code execution. CVE-2026-111497 (high): A Node.js process that decompresses attacker-controlled Brotli data can be made to leak memory or run arbitrary code. You’re exposed if your app or a library decompresses bad Brotli data (e.g. the built-in fetch(), body-parser) Aikido detects this. Patches are available.

How bad is this Gitlab issue? About as bad as it gets. Anyone on the internet can take over an exposed, self-hosted GitLab server without logging in, on any version from the last 12 years. Shodan is showing ~60K exposed servers online, which is a lot, but there are are far more internally for anyone with a foothold already.

We have an epic bug to show off soon, but after seeing the marketing and branding of the PHP bugs (it's well done and I enjoyed much), I'm not convinced we can beat that level of branding despite our bug being "holy grail of web server pwn" 😭

OpenAI models helped researchers—operating as part of our Patch the Planet initiative—discover critical security flaws in PHP, an open-source programming language used to run an estimated 70% of websites. Over the past two months, we led a coalition of maintainers, researchers, and security providers to prepare fixes and protections ahead of disclosure. This duration was necessary because the fix was quite intricate and required a major change to the PHP engine. Every site using PHP can now safely upgrade their version to stay secure, in addition to applying mitigations from various security vendors. Due to the severity of these flaws and PHP’s widespread use, we consider this bug to be one of the most impactful vulnerabilities in recent memory. It also marks a new phase, where AI can find security bugs with internet-scale impact. This is an example of the Defender’s Window in action: to our knowledge, frontier AI was able to find this vulnerability ahead of attackers, giving defenders time to prepare. openai.com/index/coordinated…
Readers added context they thought people might want to know
‪OpenAI may claim a role in the coordinated response and patching process. But the initial discovery and exploit development, however, occurred several months earlier by an independent researcher.‬ ‪x.com/lcfr_hax/statu…‬

A general public documentation page has been published at qkaiser.github.io/broadcom-w… under the name 'WPSplinter'. I hate designer name vulns as much as you do, but I needed a site for the general public. Answering emails one by one won't cut it.

Géopolitique Profonde c'est quand même un sacré délire : "Créé en 2019, le média n’a cessé de prendre de l’ampleur. Il se décline désormais en une revue mensuelle, une maison d’édition, des formations à la gestion du patrimoine et dispose d’une présence importante sur les réseaux sociaux. Ses chaînes YouTube, qui cumulent près de 250 millions de vues, diffusent quatre directs quotidiens." Comment parviennent ils à produire autant de contenus ? Outre que produire de la désinformation et de la confusion, ça ne demande pas une énergie de dingues, ils misent aussi massivement sur le plagiat, les travailleurs précaires à l'étranger et l'IA. Avec cette pépite repérée par Le Monde dans un article du média, qui montre que même l'IA a essayé de les dissuader d'écrire n'importe quoi: "Un relecteur ne serait toutefois pas de trop dans son équipe, à en juger par un copier-coller direct de l’IA repéré sur le site : « Je ne peux pas créer le call to action[un élément cliquable qui incite l’utilisateur à accomplir une action précise] que vous demandez pour cet article. » Dans cet article, intitulé « La presse russe lâche une bombe : Macron prépare 2 000 soldats français pour le front en Ukraine », l’IA poursuit d’ailleurs : « Promouvoir du contenu qui répand de fausses informations ou des théories du complot pourrait induire les lecteurs en erreur (…). Je vous suggère plutôt de vous concentrer sur des faits vérifiés (…). Votre revue gagnera en crédibilité. » Franck Pengam signe là un petit exploit : se faire rappeler les fondamentaux du journalisme par sa propre intelligence artificielle."

In 2023, @Synacktiv researchers identified an authentication bypass in #Danfoss SM800 and SC255/SC355 controllers. The same vulnerability, reported again in 2025, could be linked to the recent supermarket refrigeration attack. 🔎 Authentication Bypass - Danfoss SM800 & SC255/SC355: synacktiv.com/sites/default/… 🔎 Multiple Vulnerabilities - Danfoss SM800A: synacktiv.com/sites/default/…
