A vulnerability in aimhubio/aim version 3.25.0 allows for a denial of service through the misuse of the sshfs-client. The tracking server, which is single-threaded, can be made unresponsive by requesting it to connect to an unresponsive socket via sshfs. The lack of an additional timeout setting in the sshfs-client causes the server to hang for a significant amount of time, preventing it from responding to other requests.
The code has a synchronous call to a remote resource, but there is no timeout for the call, or the timeout is set to infinite.
This issue can prevent the product from running reliably, since an outage for the remote resource can cause the product to hang. If the relevant code is reachable by an attacker, then this reliability problem might introduce a vulnerability.
