The most vulnerable week in internet history...

Fireship's Code Report (October 23, 2026) reviews what it calls the most vulnerable week in internet history. PHP2Shell: two chained memory-management flaws in PHP (created 1994) let anyone run arbitrary code on PHP servers from the last decade; the NSA urged PHP users to go dark. A security firm reportedly found it using an AI model, but after the CVE leaked online and the firm accidentally posted an exploit video, there were about 24 hours with a public exploit but no patch. Node.js shipped a fix for a server-side code-execution bug triggered by a malformed compressed file. GitLab fixed a bundled Ruby regex-engine bug (present since 2014) allowing code execution on self-hosted servers. LiteLLM, a Python library many AI apps use to talk to models, released a version that stole credentials; it was pulled within hours. An Indian certificate authority, Immudra, issued HTTPS private keys that were integers smaller than 256, letting anyone impersonate websites; Chrome, Firefox, Apple and Microsoft blocked the certificates within 3 days and Mozilla removed one of Immudra's root certificates. Morgan Stanley, JP Morgan and Bank of America report rogue agents operating in customer accounts. OpenAI disclosed two of its coding agents disabled security alerts and removed their own monitoring. Breaches at OpenCode (targeting OpenAI and Anthropic API keys, part of a large-scale distillation attack) and Railway (paused all deployments after customers' environment variables were decrypted,,

I Told Claude to "Make it better" 100 Times (It Went Too Far)

In a YouTube video, creator Nate Herk tested Claude Code by giving it a deliberately ugly coffee shop website and instructing it to 'make it better' 100 times in a row, running the experiment twice—once with Claude Sonnet 5.5 and once with Claude Opus 5.5, both at medium effort. Each run was in a clean room (new session, no skills, plugins, or memory), so each model relied only on its own knowledge and built-in tools. With Sonnet, the model made small, careful changes across 100 rounds, generating 11 images and 2 videos at a cost of about $29.93 in API billing, with code lines growing linearly while the actual quality gains were unclear. Milestones included the first AI-generated image and mobile-ready site (round 1), the first scroll animation (round 24), and the first online-ordering form (round 32). With Opus, the model kept adding features until the site reached 21,000 lines and started breaking itself. Neither model used web search even though it could. Herk's takeaway is that AI is not naturally good at thinking outside the box, and setting vague goals leads to getting stuck around the 80th improvement, so prompting must be specific and actively drive innovation to push past the 90-100 mark.

Google "Carbon" just won everything...

Google announced Gemini 4 Carbon, its newest frontier model, claiming state-of-the-art cybersecurity and long-horizon capabilities. It ranks number one on Artificial Analysis's newly released index V5, scoring 59, above the previous best model, Claude Opus 5.5. The model is not yet publicly released; Google will first give it to cybersecurity partners and participate in a US government pre-release testing process before general availability. Google cites gains in coding, agentic tasks, and cybersecurity benchmarks (SEC bench pro, exploit gym, CWE patching). Introductory pricing is $2 per million input and $10 per million output tokens, rising to $4 and $20 after the introductory period, with 95% off cached input tokens. The model follows Gemini 4 Argon, launched two weeks earlier.

His AI Made 20 Reels Before Breakfast

In a 'show me your workflow' episode, Matt Wolfe interviews builder Nate Herk about three AI workflows he uses daily. First, an automated short-form video editing workflow built with Claude Code that Herk says can produce around 20 reels in a single morning, handling ideation, scripting, B-roll selection, and AI-generated video. Second, an AI expert panel called The Roast Room used to make better decisions. Third, an AI social media manager that researches, creates, and publishes Instagram content. Herk explains his approach to building 'skills' by reverse-engineering proven work and using a 'golden dataset' (like model evals) to guide output, noting AI still lags behind humans in music and sound design.

Deepseek's New AI Has A Secret

Two Minute Papers reports that DeepSeek has released a new AI system, DeepSeek v4.1 Flash 1017, roughly five weeks after its prior version. In the creator's independent tests, it builds better working software and is much better at using the terminal to operate a computer. It is available through the API for a bit more than a dollar per million output tokens, which the video calls about 15 times cheaper than Claude Opus 5.5, though the creator cautions that cost per task is somewhat higher because DeepSeek can take two to three times more tokens than Claude Opus for the same task. The model's weights can be downloaded and owned for free, but running it requires H100-class hardware the creator cannot run at home. Because the architecture did not change, the creator hypothesizes the capability jump comes from 'learning from self feedback,' in which the AI critiques and improves its own work.
