CVE-2026-49119 gradio-app CVE debrief
A path traversal vulnerability exists in Gradio's FileExplorer component's preprocess() method, allowing unauthenticated attackers to escape the configured root directory by supplying path segments containing directory traversal sequences or absolute paths. This can result in arbitrary file read or exposure of sensitive files outside the intended directory.

Who should care
Defenders responsible for Gradio deployments should assess exposure and prioritize patching to prevent potential file exposure. This includes reviewing compensating controls for exposed systems, checking relevant monitoring, detection, and logs for exposed assets, and tracking exceptions and retesting remediated assets. Operators, platform administrators, vulnerability management teams, and security teams should collaborate to verify Gradio versions and to
Why it matters
The CVE-2026-49119 path traversal vulnerability in Gradio's FileExplorer component allows unauthenticated attackers to access files outside the intended directory, potentially exposing sensitive information. Defenders should prioritize verifying Gradio versions and applying patches to prevent potential file exposure.
- Potential exposure of sensitive files outside intended directories
- Arbitrary file read access for attackers
- Need for verification of Gradio version and patch application
- Potential for attackers to access sensitive information
Technical summary
The FileExplorer component in Gradio before 6.16.0 has a path traversal vulnerability in its preprocess() method. This allows unauthenticated attackers to escape the configured root directory by providing path segments with directory traversal sequences or absolute paths, potentially leading to arbitrary file read or exposure of sensitive files. Defenders should prioritize verifying Gradio versions and applying patches to prevent potential file exposure. The vulnerability is confirmed in Gradio versions before 6.16.0, and defenders should review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
Defensive priority
Defenders should prioritize verifying Gradio versions and applying patches to prevent potential file exposure.
Recommended defensive actions
- Verify Gradio version and apply patch to 6.16.0 or later
- Restrict access to sensitive files and directories
- Monitor for suspicious file access attempts
- Review compensating controls for exposed systems while remediation is scheduled and verified
- Check relevant monitoring, detection, and logs for exposed assets that need extra review
- Track exceptions, retest remediated assets, and close the item only after evidence is documented
- Confirm whether affected Gradio deployments exist in managed environments and assign an owner for follow-up
Evidence notes
The vulnerability is confirmed in Gradio versions before 6.16.0. The FileExplorer component's preprocess() method is susceptible to path traversal attacks, allowing attackers to access files outside the intended directory.
