No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Hermes WebUI before 0.51.521 validates the workspace of an imported session under the active named profile but constructs the Session object without setting its profile in the /api/session/import handler, so the imported session is persisted with a null profile. Because a null profile is treated as the default profile by the profile authorization check, a user on the default profile can export the imported session transcript and use its session identifier to read files from the named profile's workspace, defeating the application's profile isolation.
