## Technical details

Missing authorization (CWE-862) in the operationGet handler for GET /1.0/operations/{uuid} allows any authenticated client to retrieve operations from any project, regardless of certificate restrictions. The handler performs no permission check before rendering the operation object, unlike the operationDelete and operationsGet handlers in the same codebase. An attacker with a project-restricted certificate and knowledge of a target operation UUID can bypass authorization and read command lines, environment variables with embedded secrets, and websocket credentials.

## Affected products

- LXC Incus before 6.0.7; 6.1.0 before 7.0.2; 7.1.0 before 7.5.0
