Denial Of Service Openclaw

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.

Analysis

OpenClaw before 2026.3.22 processes cryptographic operations on inbound Nostr direct messages prior to validating sender identity and pairing status, allowing unauthenticated remote attackers to trigger denial of service through resource exhaustion by sending crafted messages. CVSS 6.9 reflects moderate impact with low integrity and availability degradation; no public exploit code or active exploitation has been confirmed.
