Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.

Description

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).

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/stefanprodan/podinfo, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update github.com/stefanprodan/podinfo to 1.8.1-0.20260314125853-83deb7fcb742 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-mw8w-q3f7-2v85 is resolved across your whole dependency graph.

  3. Workarounds

    Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
