Affected: OpenClaw

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.

Affected: npm: openclaw

## Summary Nostr inbound DM handling could perform crypto and dispatch work before sender and pairing policy enforcement, enabling unauthorized pre-auth computation.

## Affected Packages / Versions - Package: `openclaw` (npm) - Affected: < 2026.3.22 - Fixed: >= 2026.3.22 - Latest released tag checked: `v2026.3.23-2` (`630f1479c44f78484dfa21bb407cbe6f171dac87`) - Latest published npm version checked: `2026.3.23-2`

## Fix Commit(s) - `1ee9611079e81b9122f4bed01abb3d9f56206c77`

## Release Status The fix shipped in `v2026.3.22` and remains present in `v2026.3.23` and `v2026.3.23-2`.

## Code-Level Confirmation - extensions/nostr/src/channel.ts now performs authorization before decrypting and dispatching inbound DM content. - extensions/nostr/src/nostr-bus.ts adds pre-crypto authorization, size, and rate guardrails before expensive decrypt work.

OpenClaw thanks @kuranikaran for reporting.
