Alert meAnalysisAIv1 – Mar 12, 2026
Gradio versions up to 6.7 contains a vulnerability that allows attackers to read arbitrary files from the file system (CVSS 7.5).
RemediationAI
Monitor vendor advisories for a patch. Validate and sanitize file path inputs. Use allowlists. Restrict network access to the affected service where possible.

affects Gradio. Gradio is an open-source Python package designed for quick prototyping. Prior to version 6.7, Gradio apps running on Window with Python 3.13+ are vulnerable to an absolute path traversal issue that enables unauthenticated attackers to read arbitrary files from the file system. Python 3.13+ changed the definition of os.path.isabs so that root-relative paths like /windows/win.ini on Windows are no longer considered absolute paths, resulting in a vulnerability in Gradio's logic for joining path

3DescriptionGitHub Advisory
Gradio is an open-source Python package designed for quick prototyping. Prior to version 6.7, Gradio apps running on Window with Python 3.13+ are vulnerable to an absolute path traversal issue that enables unauthenticated attackers to read arbitrary files from the file system. Python 3.13+ changed the definition of os.path.isabs so that root-relative paths like /windows/win.ini on Windows are no longer considered absolute paths, resulting in a vulnerability in Gradio's logic for joining paths safely. This can be exploited by unauthenticated attackers to read arbitrary files from the Gradio server, even when Gradio is set up with authentication. Version 6.7 fixes the issue.
Executive ViewAI
Gradio versions up to 6.7 contain a critical arbitrary file read vulnerability that could allow attackers to access sensitive organizational data including credentials, source code, and confidential files. Organizations using Gradio in production environments face immediate risk of data breach and intellectual property theft.
Implement Web Application Firewall (WAF) rules to block requests containing path traversal patterns (../, ..\, encoded variants); restrict Gradio application network access to internal networks only; disable or restrict the file serving/upload functionality in Gradio if not critical to operations; apply strict file system permissions and access controls; monitor and log all file access attempts to Gradio endpoints; consider containerization with read-only filesystems where feasible.
