CVE-2026-28450: OpenClaw < 2026.2.12 - Unauthenticated Profile Tampering via Nostr Plugin HTTP Endpoints

• Severity: high (CVSS 8.2 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-03-05 · updated 2026-06-17
• Weakness: CWE-306

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's private key when the gateway HTTP port is accessible beyond localhost.

Affected products

• OpenClaw: before 2026.2.12 — fixed in 2026.2.12

How to fix

Upgrade to a fixed version: OpenClaw 2026.2.12. Check the vendor advisory for mitigations.
