Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Gradio versions before 4.13.0 are vulnerable to path traversal through the /component_server endpoint, which lets callers invoke methods on Component classes with attacker-controlled arguments. An attacker with network access can copy arbitrary files from the host into a temporary directory and then retrieve them, reading local files, including when the app is exposed via launch(share=True). Upgrade gradio to version 4.13.0 or later.
