Description

SCart e-commerce is a free open source for businesses, built on the Laravel framework. The package s-cart/s-cart before 6.9 and the package s-cart/core before 6.9 are vulnerable to cross-site Scripting (XSS) which can lead to cookie stealing of any victim that visits the affected URL. An attacker can gain unauthorized access to that user's account through the stolen cookie.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update s-cart/core to 6.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-21149 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.
