    This story was originally published on HackerNoon at: https://hackernoon.com/ai-can-remember-your-chats-remembering-your-life-is-much-harder.

For AI to become truly useful in everyday life, it needs memory that goes beyond chat history. Building that memory means solving four key challenges: deciding what to remember, retrieving the right experience, connecting moments over time, and learning from corrections as people and circumstances change. At Looki, we’re exploring how visual evidence, supported by audio, chat, location, and other context, can create AI memory that is grounded in what actually happened—and remains understandable, verifiable, and correctable.

    From Global Allowlist to RCE: Breaking Down CVE-2026-50023 in yt-dlp

    This story was originally published on HackerNoon at: https://hackernoon.com/from-global-allowlist-to-rce-breaking-down-cve-2026-50023-in-yt-dlp. How a shortcut-extension exception in yt-dlp's CVE-2024-38519 fix opened the door to CVE-2026-50023, and what the follow-up bug teaches us. Check more stories related to tech-stories at: https://hackernoon.com/c/tech-stories.

This story was written by: @pavanchow. Learn more about this writer by checking @pavanchow's about page, and for more stories, please visit hackernoon.com. A fix for filename sanitization kept dangerous extensions on a global allowlist. I bypassed it by crafting an HLS manifest that forced yt-dlp to write a malicious .desktop file during a standard subtitle download. The patch moved the exception to the feature boundary, but a follow-up CVE proved the class was not fully closed.
