Summary Duplicate Advisory: OpenClaw: Nostr inbound DMs could trigger unauthenticated crypto work before sender policy enforcement ### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-65h8-27jh-q8wv. This link is maintained to preserve external references. ### Original Description OpenClaw before 2026.3.22 performs cryptographic and dispatch operations on inbound Nostr direct messages before enforcing sender and pairing policy validation. Attackers can trigger unauthorized pre-authentication computation by sending crafted DM messages, enabling denial of service through resource exhaustion.
