Narrative and Response

Description

Open WebUI from 0.6.42 before 0.11.4 contains an uncontrolled resource consumption vulnerability that allows authenticated users to exhaust server memory by supplying compressed remote image URLs in chat messages. Attackers can point the image field at a host returning gzip-encoded responses, which get_image_base64_from_url decompresses unbounded, causing denial of service for all users.
