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 CVE-2025-70849 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.
