pascoej
Platform security specialist
Summary
pascoej works primarily on WebKit's credential and identity surface — WebAuthn, ASCredential integration, and the new Digital Credentials / OpenID4VP request parsing — alongside a steady stream of CMake and Cocoa build-system maintenance. The security fixes cluster tightly around that same surface: a missing message check on security origin in WebAuthn IPC, null-deref and crash fixes in PIN callbacks, bounds checks in SPKI/PKCS8 key import, and two safe-browsing races where navigation and downloads proceeded before the lookup returned. Systematic-variant candidate: OpenID4VP request parsing was just moved into the web content process behind an off-by-default flag, so the attacker-controlled parsing path is new, lightly exercised, and sits next to code that has already yielded an origin message-check bug — worth enabling the flag and fuzzing the signed/multisigned request parsers.
