• CVE-2026-34225: 0.29% estimated exploitation activity in the next 30 days; percentile 21.85 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary There is a blind server side request forgery in the functionality that allows editing an image via a prompt. The affected function will perform a GET request on the URL provided by the user. There is no restriction on the domain of the provided URL allowing the local address space to be interacted with. Since the SSRF is blind (the response cannot be read) impact is port scanning of the local network because it can be confirmed if the port is open based on if the GET request failed. Details The vulnerability occurs here: https://github.com/open-webui/open-webui/blob/2b26355002064228e9b671339f8f3fb9d1fafa73/backend/openwebui/routers/images.py#L850-L916 Line 911 shows the user provided URL passed to the function loadurlimage. Within this function on line 883 HTTP/HTTPs URLs are trusted blindly and called asynchronously with requests.get. PoC The vulnerability can be reproduced with the following curl command: Impact Response differentials can be used to port scan the local…

# Patch Next advisory brief: CVE-2026-34225

Advisory: Open WebUI has Blind Server Side Request Forgery in its Image Edit Functionality
IDs: CVE-2026-34225, GHSA-jgx9-jr5x-mvpv
Record: https://patchnext.com/advisories/cve-2026-34225 (revision 2, source checked 26 Oct 2026, 13:46 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 4.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI open-webui: affected <= 0.7.2

## Suggested inspection (read-only)
- `python -m pip show open-webui`: prints the installed version. Run with the environment that serves production active.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on open-webui.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
