AES-GCM Nonce Length Validation Flaw in Go Standard Library

Publication date: 2026-10-23

Last updated on: 2026-10-23

Assigner: Eclipse Foundation

Description
`AesGcmCryptor.Open` passed a caller-supplied nonce straight to `cipher.AEAD.Open` without checking its length. The Go standard library **panics** rather than returning an error when a GCM nonce is not exactly `NonceSize()` bytes, so a JWE carrying a wrong-sized IV crashes the decrypting goroutine.
