CVE-2024-5127 — Lunary Lunary security vulnerability

Medium CVSS 5.4

In lunary-ai/lunary versions 1.2.2 through 1.2.25, an improper access control vulnerability allows users on the Free plan to invite other members and assign them any role, including those intended for Paid and Enterprise plans only. This issue arises due to insufficient backend validation of roles and permissions, enabling unauthorized users to join a project and potentially exploit roles and permissions not intended for their use. The vulnerability specifically affects the Team feature, where the backend fails to validate whether a user has paid for a plan before allowing them to send invite links with any role assigned. This could lead to unauthorized access and manipulation of project settings or data.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
