Vulnerability details
parisneo/lollms-webui is vulnerable to authentication bypass due to insufficient protection over sensitive endpoints. The application checks if the host parameter is not '0.0.0.0' to restrict access, which is inadequate when the application is bound to a specific interface, allowing unauthorized…

access to endpoints such as '/restart_program', '/update_software', '/check_update', '/start_recording', and '/stop_recording'. This vulnerability can lead to denial of service, unauthorized disabling or overriding of recordings, and potentially other impacts if certain features are enabled in the configuration.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Authorizing remote access reduces the ability to bypass authentication via unauthorized alternate remote channels.
Users can identify logons via alternate paths or channels by reviewing the previous logon time.
Adaptive requirements can apply across access paths, reducing the ability to bypass authentication via alternate channels or paths.
Centralized IdPs close alternate authentication paths that enable bypass.
Enforces authentication for non-organizational users, making it harder to bypass via alternate paths or channels.
Requires authentication to occur exclusively over the isolated trusted path, directly preventing bypass via alternate or untrusted channels.
