CVE-2026-28450

OpenClaw < 2026.2.12 - Unauthenticated Profile Tampering via Nostr Plugin HTTP Endpoints

Assigner: VulnCheck
Reserved: 27.02.2026 Published: 05.03.2026 Updated: 09.03.2026

OpenClaw versions prior to 2026.2.12 with the optional Nostr plugin enabled expose unauthenticated HTTP endpoints at /api/channels/nostr/:accountId/profile and /api/channels/nostr/:accountId/profile/import that allow reading and modifying Nostr profiles without gateway authentication. Remote attackers can exploit these endpoints to read sensitive profile data, modify Nostr profiles, persist malicious changes to gateway configuration, and publish signed Nostr events using the bot's private key when the gateway HTTP port is accessible beyond localhost.
