Description

n8n is an open source workflow automation platform. Prior to 1.123.55, 2.25.7, and 2.26.2, a member-level user with editor access to a shared workflow could reference credentials they do not own via specific public API endpoints. Credential ownership checks were only enforced partially leading to cross-user credential access. This issue affects instances where workflow sharing is enabled and at least one workflow has been shared with a member-level user as an Editor. This vulnerability is fixed in 1.123.55, 2.25.7, and 2.26.2.

Affected configurations

• n8n n8n (< 1.123.55) • n8n n8n (>= 2.0.0 < 2.25.7) • n8n n8n (>= 2.26.0 < 2.26.2)
