🐘wwbn/avideo

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

The PHP file view/about.php is vulnerable to an XSS issue due to no sanitization of the user agent.

At line [53], the website gets the user-agent from the headers through $_SERVER['HTTP_USER_AGENT'] and echo it without any sanitization.

In PHP, echo a user generated statement, here the User-Agent Header, without any sanitization allows an attacker to inject malicious scripts into the output of a web page, which are then executed in the browser of anyone viewing that page.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update wwbn/avideo to 14.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-34899 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.
