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

Reflected Cross-Site Scripting (XSS) may allow an attacker to execute JavaScript code in the context of the victim’s browser. This may lead to unauthorised actions being performed, unauthorised access to data, stealing of session information, denial of service, etc. An attacker needs to coerce a user into visiting a link with the XSS payload to be properly exploited against a victim.

The OpenCart Overclocked OpenBay template overly trusts user-controlled input. This lack of sufficient sanitisation allows an attacker to execute JavaScript code in the context of a victim’s browser.

The code below displays unsanitised input being displayed on the victim’s page (found on line 95 upload/admin/view/template/extension/openbay.tpl#L95):

var token = "<?php echo $_GET['token']; ?>";

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Remediation status

    The records we use list no patched version of villagedefrance/opencart-overclocked for GHSA-cr3q-658v-qv3x. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    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.
