Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

Description

Adobe Commerce versions 2.4.9-alpha1, 2.4.8-p1, 2.4.7-p6, 2.4.6-p11, 2.4.5-p13, 2.4.4-p14 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be exploited by a low-privileged attacker to inject malicious scripts into vulnerable form fields. A successful attacker can abuse this to achieve session takeover, increasing the confidentiality and integrity impact as high. Exploitation of this issue requires user interaction in that a victim must browse to the page containing the vulnerable field. Scope is changed.

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/community-edition, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update magento/community-edition to 2.4.4-p15 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8mq8-c243-2335 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.

Frequently Asked Questions

Adobe Commerce versions 2.4.9-alpha1, 2.4.8-p1, 2.4.7-p6, 2.4.6-p11, 2.4.5-p13, 2.4.4-p14 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be exploited by a low-privileged attacker to inject malicious scripts into vulnerable form fields. These scripts may be used to escalate privileges within the application or compromise sensitive user data. Exploitation of this issue requires user interaction in that a victim must browse to the page containing the vulnerable field. Scope is changed.
