Description

Adobe Commerce versions 2.4.7-p1, 2.4.6-p6, 2.4.5-p8, 2.4.4-p9 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by a low-privileged attacker to inject malicious scripts into vulnerable form fields. Malicious JavaScript may be executed in a victim’s browser when they browse to the page containing the vulnerable field. Confidentiality impact is high due to the attacker being able to exfiltrate sensitive information.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    A fix is available for CVE-2024-39403; check the affected-versions list above or the advisory for the patched release of magento/project-community-edition, then make sure no transitive dependency still pins the vulnerable range.

  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.
