Hubuum client library (Rust): Authenticated requests may escape the configured base path through redirects
GitHub lists this reviewed advisory for hubuum_client. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.

source listed>= 0.0.1, < 0.6.1
## Impact The built-in async and blocking clients used reqwest's default redirect policy. `BaseUrl` constrains the initial request to the configured origin and path prefix, but redirect processing occurs after that validation. reqwest retains sensitive headers when a redirect changes only the path on the same scheme, host, and port. A redirect from a Hubuum endpoint to another path on a shared origin could therefore carry the bearer `Authorization` header outside the configured Hubuum path prefix. Exploitation requires an attacker, compromised server, or intermediary to influence a 3xx response. Cross-origin redirects are not affected because reqwest strips sensitive headers when scheme, host, or port changes. ## Patches Version 0.6.1 configures both built-in HTTP clients with `reqwest::redirect::Policy::none()`. Redirect responses are returned as 3xx API errors instead of being followed. Supplying a preconfigured reqwest client remains an explicit opt-in to that client's redirect policy. ## Workarounds On affected versions, construct a reqwest client with `reqwest::redirect::Policy::none()` and pass it through `with_http_client`. Deployments can also reduce exposure by ensur

What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
