Arbitrary Local File Read in Gradio via Component Method Invocation
A vulnerability in Gradio version 4.12.0 allows attackers to read arbitrary files on the server by exploiting the `/component_server` endpoint to call any method on a `Component` class, specifically `move_resource_to_block_cache()`. This issue was patched in version 4.13.0.
