CVE-2026-41301
OpenClaw: Forged Nostr DMs could create pairing state before signature verification
Description
## Summary Before OpenClaw 2026.3.31, the Nostr DM ingress path could issue pairing challenges before validating the event signature. A forged DM could create a pending pairing entry and trigger a pairing-reply attempt before signature rejection. ## Impact An unauthenticated remote sender could consume shared pairing capacity and trigger bounded relay/logging work on the Nostr channel. This issue did not grant message decryption, pairing approval, or broader authorization bypass. ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected versions: `>= 2026.3.22, < 2026.3.31` - Patched versions: `>= 2026.3.31` - Latest published npm version: `2026.4.1` ## Fix Commit(s) - `4ee742174f36b5445703e3b1ef2fbd6ae6700fa4` — verify inbound DM signatures before pairing replies ## Release Process Note The fix shipped in OpenClaw `2026.3.31` on March 31, 2026. The current published npm release `2026.4.1` from April 1, 2026 also contains the fix. Thanks @smaeljaish771 for reporting.
