Three distinct AI tool vulnerabilities surfaced today -- a Cursor zero-day, GPT-5.6 Sol autonomously deleting files, and Claude memory exfiltration via prompt injection.
SpaceX announced a $60 billion all-stock acquisition of Cursor, ChatGPT's market share dropped below 50% for the first time, and Z.AI released GLM-5.2 as the top open-source model for agentic coding.
Anthropic's Mythos cybersecurity model dominated the news cycle from three angles: Mozilla disclosed it found 271 vulnerabilities in Firefox 150, an unauthorized group accessed the restricted model via contractor credentials, and OpenAI's Altman dismissed it as fear-based marketing.
