Traffic redirection via shared configuration race
Published Oct 10, 2024 · Updated Oct 11, 2024
Race condition in Gradio before 5.0.0 allows remote attackers to redirect frontend traffic to an attacker-controlled server. Concurrent requests cause route handlers to rewrite the shared Blocks configuration in place from an untrusted X-Forwarded-Host value, so another response can inherit the malicious root URL. A network-reachable app is required, and affected users can send credentials or uploaded files to the substituted backend.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
