CVE-2026-67541: Heym team-member management privilege escalation

CVE-2026-67541 · Severity: high · CVSS 8.1 · Published 2026-11-11

Heym is a platform for building and running automated systems and workflows on self-hosted infrastructure. Non-creator team members could exploit weak authorization checks to add attacker accounts to a team and then decrypt all shared credentials (API keys, OAuth tokens) without admin permission. This allows credential theft and potential account takeover of integrated services.

Technologies: Heym. Vendors: Heym.

Technical details

Team-member add/remove/update operations were gated only on team membership rather than requiring creator/admin role, and the TeamMember schema lacked a role column. Any non-creator member could seat an arbitrary account into a team, then access all credentials shared into that team since credential team-shares are scoped only by TeamMember.user_id. The fix restricts these operations to the team creator and adds regression tests.
