Description

A stored cross-site scripting (XSS) vulnerability in Shopizer before 2.17.0 allows remote attackers to inject arbitrary web script or HTML via customer_name in various forms of store administration. It is saved in the database. The code is executed for any user of store administration when information is fetched from the backend, e.g., in admin/customers/list.html.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update com.shopizer:shopizer to 2.17.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rcp4-jm2v-mr3f 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.
