CVE-2026-28450

Severity CVSS v4.0:

HIGH

Type:

CWE-306 Missing Authentication for Critical Function

Publication date:

05/03/2026

Last modified:

09/03/2026

Description

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&#39;s private key when the gateway HTTP port is accessible beyond localhost.
