CVE-2025-70849Public exploitNetwork attack vector

Stored XSS via unrestricted /store uploads

Published Feb 3, 2026 · Updated Feb 3, 2026

Stored cross-site scripting in Podinfo 6.9.0 and earlier allows remote attackers to execute scripts through unauthenticated /store uploads. The storeReadHandler returns attacker-supplied bodies without a fixed content type, nosniff protection, or a restrictive CSP, so browsers render uploaded HTML and JavaScript. No account is required to upload content, but a victim must visit the generated /store hash URL; execution is confined to that victim's Podinfo origin.
