AI finds subtle architecture-level bugs, not just the memory exploits ASan can catch

Responding to Joshua Saxe, stanislavfort argues that vulnerabilities deterministically verifiable via an ASan crash are the less interesting kind—ones classic fuzzing could in principle catch. From his hands-on work, the most valuable AI-discovered vulnerabilities are subtle logical flaws in how a codebase is architected, citing CVE-2025-66491 discovered by AISLEInc as an example. He adds that their attacks on Cursor, Visual Studio, and Antigravity were emphatically nothing an ASan would ever catch.
