Original description The description as published by the source.
JweDirectDecryptorBlock.Decrypt read a 64-bit plaintext length from the _thales_aad protected-header field and used it without any validation. A truncated field panics binary.BigEndian.Uint64, an oversized value drives an unbounded allocation, and a value larger than the decrypted block panics with a slice-bounds error.
