CVE-2026-45395 1 Open-webui 1 Open-webui 2026-05-18 7.2 High
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.5, the tool update endpoint (POST /api/v1/tools/id/{id}/update) is missing the workspace.tools permission check that is present on the tool create endpoint. This allows a user who has been explicitly denied tool management capabilities ( and who the administrator considers untrusted for code execution ) to replace a tool's server-side Python content and trigger execution, bypassing the intended workspace.tools security boundary. This vulnerability is fixed in 0.9.5.
CVE-2026-44569 1 Open-webui 1 Open-webui 2026-05-18 7.1 High
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.6.19, there's an IDOR in the channels message management system that allows authenticated users to modify or delete any message within channels they have read access to. The vulnerability exists in the message update and delete endpoints, which implement channel-level authorization but completely lack message ownership validation. While the frontend correctly implements ownership checks (showing edit/delete buttons only for message owners or admins), the backend APIs bypass these protections by only validating channel access permissions without verifying that the requesting user owns the target message. This creates a client-side security control bypass where attackers can directly call the APIs to modify other users' messages. This vulnerability is fixed in 0.6.19.

CVE-2021-44793 1 Krontech 1 Single Connect 2026-05-18 8.6 High
Single Connect does not perform an authorization check when using the sc-reports-ui" module. A remote attacker could exploit this vulnerability to access the device configuration page and export the data to an external file. The exploitation of this vulnerability might allow a remote attacker to obtain sensitive information including the database credentials. Since the database runs with high privileges it is possible to execute commands with the attained credentials.
CVE-2021-44794 1 Krontech 1 Single Connect 2026-05-18 5.3 Medium
Single Connect does not perform an authorization check when using the "sc-diagnostic-ui" module. A remote attacker could exploit this vulnerability to access the device information page. The exploitation of this vulnerability might allow a remote attacker to obtain sensitive information.
CVE-2021-44795 1 Krontech 1 Single Connect 2026-05-18 5.3 Medium
Single Connect does not perform an authorization check when using the "sc-assigned-credential-ui" module. A remote attacker could exploit this vulnerability to modify users permissions. The exploitation of this vulnerability might allow a remote attacker to delete permissions from other users without authenticating.
CVE-2021-44792 1 Krontech 1 Single Connect 2026-05-18 5.3 Medium
Single Connect does not perform an authorization check when using the "log-monitor" module. A remote attacker could exploit this vulnerability to access the logging interface. The exploitation of this vulnerability might allow a remote attacker to obtain sensitive information.
