Summary

Gradio Vulnerable to Denial of Service (DoS) via Crafted HTTP Request

Details

A Regular Expression Denial of Service (ReDoS) vulnerability exists in the gradio-app/gradio repository, affecting the gr.Datetime component. The affected version is git commit 98cbcae. The vulnerability arises from the use of a regular expression ^(?:\s*now\s*(?:-\s*(\d+)\s*([dmhs]))?)?\s*$ to process user input. In Python's default regex engine, this regular expression can take polynomial time to match certain crafted inputs. An attacker can exploit this by sending a crafted HTTP request, causing the gradio process to consume 100% CPU and potentially leading to a Denial of Service (DoS) condition on the server.

Severity

7.5 (High)
