Perses's project query parameter authorization bypass exposes cross-project resources
### Impact _What kind of vulnerability is it?_ An authenticated user who is only a viewer on project team-a requests GET /api/v1/projects/team-a/dashboards?project=finance-secret (or simply GET /api/v1/datasources?project=finance-secret) and receives the full list of the finance-secret project's dashboards and datasource specifications, despite having no role on that project. This defeats Perses' project-level tenant isolation for all project-scoped read resources. _Who is impacted?_ Any authenticated user reads every project's dashboards, datasources, variables across tenants. ### Patches _Has the problem been patched? What versions should users upgrade to?_ ### Workarounds None
