CVE-2025-8791Public exploitNetwork attack vector

Project takeover via client-trusted role response

Published Aug 10, 2025 · Updated Aug 13, 2025

Improper authorization in LitmusChaos Litmus 3.0 through 3.19.0 allows remote authenticated users to take over accessible projects. The web client accepts a role value from the /auth/list_projects response after it is changed from Viewer to Owner, rather than enforcing the server-assigned role for later actions. Viewer access to a project is required; successful exploitation grants owner-level actions, including changing project resources and deleting experiments.
