CVE-2026-62241Public exploitNetwork attack vector

Unauthenticated account takeover via forged JWT sessions

Published Jul 17, 2026 · Updated Jul 17, 2026

Authentication bypass in ClawVet before 0.7.5 allows remote attackers to impersonate self-hosted API users and read account secrets. The API exposes userId values without authentication, while auth.ts verifies HS256 cg_session cookies with a known fallback secret also shipped in .env.example. Network access to an API using that default is sufficient to read a victim's email, plan, and apiKey and perform authenticated API operations.
