description

SolarWinds Observability Self-Hosted has an authorization-control flaw. A user with limited permissions may be able to view or modify information beyond the access they were assigned.

mitigation

Restrict access to the deployment to trusted users, remove unnecessary low-privilege accounts, and review authorization-related activity for unexpected access. Apply a vendor update when SolarWinds publishes a fixed release; no fixed version is recorded in the available advisory data.
