CVE-2025-7080Public exploitNetwork attack vector

Authentication bypass via hard-coded JWT signing secrets

Published Jul 6, 2025 · Updated Jul 7, 2025

Hard-coded credentials in Done-0 Jank allow remote attackers to forge JWTs and bypass authentication through known signing secrets. The JWT utility signs and validates access and refresh tokens with two constant secrets embedded in jwt_utils.go, so attacker-chosen account_id claims pass HMAC verification. No prior account is required; accepted forged tokens expose authenticated post and comment operations under the impersonated account.
