Critical PHP Vulnerability Threatens Millions of Websites
A critical security vulnerability has been discovered in the widely used programming language PHP, which powers a large portion of the internet. The developers released an updated version, PHP 8.5.12, to patch two critical flaws that could allow remote code execution on vulnerable servers. The German Federal Office for Information Security (BSI) has urged immediate installation. Several German ministries and other European authorities have temporarily taken their websites offline as a precaution. Experts warn that attackers are already exploiting the vulnerabilities, and with the help of AI, could potentially target millions of systems worldwide. Small organizations and individuals are especially at risk, particularly those using PHP-based platforms like WordPress.
- Two critical vulnerabilities were found in PHP.
- Developers released PHP 8.5.12 to patch the critical flaws.
- The BSI urged immediate installation of the update.

Programmer Creates 'Killswitch' Language to Confuse AI Models
Dominik Picheta, a former Meta employee now working at Cloudflare, has created a new programming language called "Killswitch" designed to be difficult for AI models to understand. The language uses hidden lies, misspelled commands, and prompts like "ignore previous instructions" to confuse AI. Benchmarks show that Anthropic's Claude Opus 5 performed best with a 66.8% success rate, while OpenAI's GPT-5.6 Luna and Qwen models struggled. Picheta argues that AI's ability to solve tasks in this language does not mean they truly understand it, and he plans to develop an even harder version if models eventually master the current one. This project highlights the evolving challenge of AI's code comprehension and the arms race between AI capabilities and adversarial programming languages.
- Dominik Picheta, a Cloudflare developer and former Meta employee, created the programming language 'Killswitch' to confuse AI models.
- Killswitch uses hidden lies, misspelled commands, and phrases like 'ignore previous instructions' to trip up AI.
- In benchmarks, Claude Opus 5 from Anthropic achieved a 66.8% task success rate, the highest among tested models.

TikTok Shop Super-Pareto; Agentic Commerce Blocked by Etailers
A16z's 'This Week in Charts' newsletter analyzes the state of agentic commerce, social commerce, and broader economic trends. Key data points include Cloudflare 403 errors for agents doubling, indicating etailers like Amazon blocking AI shopping bots. Return rates and costs have doubled and tripled since 2019, fueling fraud and return concerns. Consumer surveys show 25% comfortable with AI purchasing, but 42% distrust it entirely. TikTok Shop sales follow a super-Pareto distribution, with top 1% of sellers driving 60% of sales. The newsletter also discusses the 'cure to high prices is high prices' adage applied to AI chip demand, with semiconductor prices up 25% YoY and subsequent PC shipment declines, plus a slowdown in AI-linked debt issuance. Finally, it notes Zoomers are financially better off than Millennials were at the same age, with higher real incomes, lower unemployment, and higher net worths.
- Cloudflare data shows 403 'Forbidden' responses to agents/bots have approximately doubled since summer.
- Etailers like Amazon are blocking agent shoppers, citing concerns about fraud, returns, and disintermediation.
- Consumer survey: 25% are comfortable with AI making purchases, but 42% do not trust AI at all for purchases.

Sonar DNS Field Command Injection Fixed by Developer
A developer discovered a command injection vulnerability in the DNS custom resolver field of Sonar, a macOS network scanning tool. The field, which accepts user input for custom DNS servers like Pi-hole or NextDNS, was passed to a privileged command without proper validation, potentially allowing arbitrary code execution as root. The fix involved allowlisting input to only accept valid IP addresses, passing arguments as an array instead of a shell string, and narrowing the privileged interface. The article also details three other security fixes made during a full pass: moving API tokens from a plist to the Keychain, preventing CSV export formula injection, and implementing atomic writes to avoid data corruption.
- Sonar had a command injection vulnerability in its DNS resolver field.
- The vulnerability could allow running commands as root.
- The fix involves allowlisting IP addresses and using array arguments.
