CVE-2025-8795Public exploitNetwork attack vector

Cross-tenant project access via trusted login response

Published Aug 10, 2025 · Updated Aug 13, 2025

Improper access control in LitmusChaos Litmus 3.0 through 3.19.0 allows remote authenticated users to access other users' projects. The /auth/login flow stores project IDs and roles in client-side response data, then subsequent requests fail to validate server-side ownership after projectID substitution. A valid low-privilege account and response interception are required; successful exploitation exposes cross-tenant data and permits project changes or deletion.
