What is CVE-2026-54014?

Open WebUI, a self-hosted AI platform, has a vulnerability that permits authenticated users to read files from unexpected directories. This arises from an incomplete validation check in the serve_cache_file() function, allowing paths that align with sibling directory names to bypass intended restrictions. Specifically, the cache file serving mechanism fails to append a required path separator, potentially leading to unauthorized data exposure. This issue was rectified in version 0.9.6, highlighting the importance of using updated software to ensure security integrity.
