Description
Gradio before 6.16.0 contain a path traversal vulnerability in the FileExplorer component's preprocess() method that allows unauthenticated attackers to escape the configured root directory by supplying path segments containing directory traversal sequences or absolute paths. Attackers can provide crafted path segments that cause os.path.join to discard the root_dir prefix entirely, resulting in arbitrary file read or exposure of sensitive files outside the intended directory.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for gradio, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update gradio to 6.16.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-j36p-7w88-g82j is resolved across your whole dependency graph.
Workarounds
Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
