Heym 0.0.55 before 0.0.121 Credential Theft via error_workflow_id Field

Published Oct 14, 2026 · updated Oct 14, 2026 · heymrun heym

Heym from 0.0.55 before 0.0.121 contains a privilege escalation vulnerability that allows shared collaborators to overwrite a workflow's error_workflow_id because the field is missing from OWNER_ONLY_EXECUTION_FIELDS.
