CVE-2024-8135Network attack vector

Authentication bypass via hard-coded JWT signing key

Published Aug 24, 2024 · Updated Aug 26, 2024

Hard-coded signing key in token.go in Go-Tribe gotribe through cd3ccd32cd77852c9ea73f986eaf8c301cfb6310 allows remote attackers to forge JWTs. pkg/token/token.go initializes config.key to a source-visible constant, and Sign passes that value to SignedString for HS256 token generation. Knowledge of the published key is sufficient to mint tokens containing attacker-chosen identity claims, enabling unauthenticated impersonation wherever the application trusts those tokens.
