Description

Wallet event parsers accept unauthenticated events

The NIP-47 response and notification parsers and the NIP-60 wallet event parsers

decrypted relay-provided events before verifying their kind, computed event ID,

signature, and expected wallet public key. The decryption peer was derived from the

untrusted event author, so successful decryption did not prove that the configured

wallet created the event.

An attacker can sign an event with their own key and derive the corresponding shared

secret with the victim's public key. A malicious relay delivering that event could

therefore cause attacker-chosen encrypted content to be parsed as a response,

notification, token, spending record, or quote from the configured wallet. This can

corrupt wallet state or cause an application to act on forged wallet data. The issue

does not expose the victim's private key or decrypt events authored by the legitimate

wallet.

The affected parsers now verify the event kind, ID, signature, and exact configured

wallet author before attempting decryption or parsing the plaintext.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity high, availability none.
