Description

Processing of unverified relay events

The processed events received from a relay through admission-policy and database

paths before verifying that the serialized fields matched the claimed event ID and

signature. In particular, a database result for the claimed ID could cause

verification to be skipped. The verification cache also keyed successful checks by a

64-bit hash instead of the complete event ID.

A malicious relay could send an event whose claimed ID referred to a known database

entry while its content, tags, author, or signature differed from that ID. The forged

event could then reach policy callbacks or other SDK processing as if it were

authentic. A cache-key collision provided a second path for an unverified event to be

treated as previously verified. This undermines event integrity but does not reveal

private keys or enable the attacker to produce a valid signature for the altered

event.

The SDK now verifies each event before policy evaluation, database lookup, or

propagation decisions, and the verification cache stores the complete EventId so a

truncated hash collision cannot stand in for successful verification.

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.
