Technical description

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. Prior to 0.11.1, POST /api/v1/retrieval/process/web and POST /api/v1/retrieval/process/web/search in backend/open_webui/retrieval/web/utils.py treated Python's globally routable address classification as proof that a destination was external. An authenticated user could make an Azure-hosted instance fetch and return content from 168.63.129.16, the Azure platform channel, as well as other reserved ranges that the standard classification did not reject. This issue is fixed in version 0.11.1.

———IBM DataStage on Cloud Pak for Data 5.4.0.0 allows any authenticated tenant — with no project membership or role — fully controls scheme/host/port/path of an outbound fetch originating from a shared-infrastructure pod, and the WSDL body is reflected verbatim to the caller. The ds-canvas pod sits on the OpenShift overlay with reach to co-tenant services, in-cluster CP4D APIs, and link-local addresses. Scope is Changed, confidentiality High (response-reflecting), integrity Low (GET-only side-effects).6h CVE-2026-797235.0 MED

———Transmute is a free, open-source, self-hosted file conversion and compression tool. Prior to version 1.3.0, Transmute's URL import endpoint, `POST /api/files/url`, is vulnerable to Server-Side Request Forgery (SSRF). The HTTP downloader used by this endpoint fetches user-supplied URLs with redirects enabled and does not validate whether the target resolves to a public, external address. As a result, an authenticated user (or guest user if they are enabled) may be able to cause the Transmute server to make HTTP requests to internal or cloud-local resources from the server's network position. Because downloaded content is stored and can later be retrieved through `GET /api/files/{id}`, this issue can result in full-read SSRF rather than blind SSRF. This is fixed in version 1.3.0.6h
