Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-434: Unrestricted Upload of File with Dangerous Type, where the product allows the upload or transfer of dangerous file types that are automatically processed within its environment. In Github.com/stefanprodan/podinfo, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Arbitrary File Upload in podinfo thru 6.9.0 allows unauthenticated attackers to upload arbitrary files via crafted POST request to the /store endpoint. The application renders uploaded content without a restrictive Content-Security-Policy (CSP) or adequate Content-Type validation, leading to Stored Cross-Site Scripting (XSS).
