How to Fix CVE-2026-34225
To remediate this vulnerability, upgrade all affected Open webui dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
pip install open-webui>=Latest secure releaseRun the following command in your project directory to verify that all resolved dependencies use the patched release:
pip show open-webuiHow to Check if You Are Affected
To determine whether your Python environment is affected by CVE-2026-34225, inspect your installed packages using pip:
pip show open-webuiAnalyze the terminal output to locate any version of Open webui in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.
Note: The pip show open-webui command checks currently installed packages in your active Python environment.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In Open webui, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"summary" : "Open WebUI has Blind Server Side Request Forgery in its Image Edit Functionality",
"details" : "### Summary\nThere 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.\n\n### Details\nThe vulnerability occurs here:\nhttps://github.com/open-webui/open-webui/blob/2b26355002064228e9b671339f8f3fb9d1fafa73/backend/open_webui/routers/images.py#L850-L916\nLine 911 shows the user provided URL passed to the function `load_url_image`. Within this function on line 883 HTTP/HTTPs URLs are trusted blindly and called asynchronously with `requests.get`. \n\n### PoC\nThe vulnerability can be reproduced with the following curl command:\n```\ncurl -X POST http://localhost:3000/api/v1/images/edit \\\n -H \"Authorization: Bearer <token>\" \\\n -H \"Content-Type: application/json\" \\\n -d '{\"form_data\":{\n \"image\": \"<url>\",\n \"prompt\": \"poc\"}\n }'\n```\n\n### Impact\nResponse differentials can be used to port scan the local network:\n<img width=\"3016\" height=\"736\" alt=\"image\" src=\"https://github.com/user-attachments/assets/93b4df52-b23c-4ed7-a5fa-9cbedb30091c\" />\nThis can be automated to iterate through the entire port range to determine open ports. If the service running on an open port can be inferred the user may be able to interact with it in a meaningful way if the service offers any state changing GET request endpoints.\n\n### Remediation\nRestrict provided URLs from local address space.",
