What happened
Security-focused digest covering hidden capabilities and cryptographic backdoors in AI model weights, geopolitical and safety-related behavior in Qwen3-Coder, critically weak eMudhra TLS certificate keys, critical unauthenticated remote-code-execution vulnerabilities in PHP, a possible Cellebrite iPhone radio zero-day, adaptive AI CAPTCHA solving, and backdoors in modified open-weight models. The most urgent items are the PHP vulnerabilities and compromised TLS certificates; the AI model supply-chain and hidden-capability research represent significant emerging risks.
