Title
OpenClaw < 2026.3.22 - Unauthenticated Cryptographic Work in Nostr Inbound DM Handling
Summary
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.
