From Third-Party to First-Party: Measuring and Protecting against Modern Web Tracking Mechanisms

Web user tracking has always been a cat-and-mouse game between privacy-conscious users and trackers. Recently, this conflict has driven a shift from third-party tracking toward first-party tracking FPT and server-side tracking SST. By relocating tracking logic to the browser's first-party context...

GHSA-9R4W-JG96-92MV Go-Attestation: Hash injection into trusted measurement list via unskipped SignatureHeaderSize vendor bytes in parseEfiSignatureList()

Summary parseEfiSignatureList in attest/internal/events.go does not skip SignatureHeaderSize vendor bytes before reading EFISIGNATURELIST signature entries, violating UEFI specification section 31.4.1.
