How do I detect GHSA-fpqv-x9hm-35j9 in my Packagist dependencies?

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

How do I mitigate GHSA-fpqv-x9hm-35j9 if there is no patch (or I can't update yet)?

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.

Is GHSA-fpqv-x9hm-35j9 actively exploited in the wild?

Real-World Exposure

1 pkg affected

🐘kitodo/presentation

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

Impact

Kitodo.Presentation fails to properly encode URL parameters for output in HTML making it vulnerable to Cross Site Scripting (XSS). Only sites using the ListView, Navigation or PageView plugins are affected.

It also includes jQuery 3.4.1 which is known to be vulnerable against Cross Site Scripting, although there is currently no known way to exploit this in Kitodo.Presentation.

Patches

An updated version of Kitodo.Presentation is available on GitHub, Packagist and in the TYPO3 Extension Repository. Users are advised to update as soon as possible.

The issue was also fixed in release 2.3.1 of the 2.x branch, although it is generally not recommended to run this branch since it depends on an outdated TYPO3 version.
