CVE-2026-58174
Hermes WebUI < 0.51.521 - Cross-Profile Authorization Bypass via Unset Session Profile on Import
Description
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.
