CyberRota Analysis
AI-GeneratedThe vulnerability affects the @libp2p/gossipsub component in JavaScript versions 15.0.0 to 16.0.5, allowing unauthenticated attackers to impersonate RSA peer IDs by manipulating message signatures. This can lead to unauthorized data being processed under false attribution, impacting systems that rely on message origin for validation, authorization, or logging. Organizations utilizing affected versions should prioritize patching to version 16.0.5 to mitigate the risk of exploitation.

Original NVD Description
libp2p is a JavaScript implementation of the libp2p networking stack. From 15.0.0 until 16.0.5, @libp2p/gossipsub uses the default StrictSign policy in packages/gossipsub/src/utils/buildRawMessage.ts, where validateToRawMessage verifies a signature with attacker-controlled msg.key but skips binding that key to msg.from when the claimed author is an RSA peer ID that does not inline a public key. An unauthenticated attacker can place a victim RSA peer ID in msg.from, sign the message with the attacker's private key, and supply the attacker's public key in msg.key, causing the message to be accepted and propagated as authored by the victim. Applications that trust message.from for validators, authorization, accounting, moderation, reputation, or audit logging can process attacker-controlled data under false origin attribution. The issue is fixed in version 16.0.5.
