Description
Heym builds and runs agentic systems and business-process automations on self-hosted infrastructure. Prior to version 0.0.70, team-member management (add / remove / update) is gated only on team membership, not on the team creator/admin role — and TeamMember has no role column. Any non-creator member can seat an attacker account into the team; because credential team-shares are scoped only by TeamMember.user_id, the newly-added attacker can then decrypt every credential shared into that team (provider API keys, OAuth tokens. This issue has been patched in version 0.0.70.
