What is CVE-2026-34225?

The Open WebUI AI platform, a self-hosted solution designed for offline operation, is susceptible to a Blind Server Side Request Forgery. This vulnerability exists in the image editing functionality, where an attacker can leverage a GET request sent to a user-specified URL without domain restrictions. Consequently, this flaw enables potential port scanning within the local network environment. As the SSRF is blind, the response is not accessible, which allows an attacker to determine the status of ports based on whether requests succeed or fail. By automating this process, an intruder could systematically map open ports, and should any services running on those ports have state-changing GET request endpoints, there exists a risk of interaction with them. Security measures should be implemented to address this issue effectively.
