How severe is GHSA-6784-9c82-vr85?

GHSA-6784-9c82-vr85 has a CVSS score of 6.1/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by GHSA-6784-9c82-vr85?

GHSA-6784-9c82-vr85 affects the following packages: sulu/sulu (Packagist), sulu/sulu (Packagist). Ecosystems affected: Packagist.

How do I fix GHSA-6784-9c82-vr85?

Update sulu/sulu to 2.6.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6784-9c82-vr85 is resolved across your whole dependency graph.

How do I detect GHSA-6784-9c82-vr85 in my Packagist dependencies?

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

How do I mitigate GHSA-6784-9c82-vr85 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-6784-9c82-vr85 actively exploited in the wild?

No public exploit code has been indexed for GHSA-6784-9c82-vr85 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-6784-9c82-vr85?

GHSA-6784-9c82-vr85 has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 34th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-6784-9c82-vr85?

GHSA-6784-9c82-vr85 is classified as Cross-site Scripting (XSS) (CWE-79). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-6784-9c82-vr85 published, and has it been updated?

GHSA-6784-9c82-vr85 was published on October 3, 2024 and was last updated on October 17, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

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

This vulnerability allows an attacker to inject arbitrary HTML/JavaScript code through the media download URL in Sulu CMS. It affects the SuluMediaBundle component. The vulnerability is a Reflected Cross-Site Scripting (XSS) issue, which could potentially allow attackers to steal sensitive information, manipulate the website's content, or perform actions on behalf of the victim.

Patches

The problem has not been patched yet. Users should upgrade to patched versions once they become available. Currently affected versions are:

2.6.4
2.5.20

Workarounds

Until an official patch is released, users can implement additional input validation and output encoding for the 'slug' parameter in the MediaStreamController's downloadAction method. Alternatively, configuring a Web Application Firewall (WAF) to filter potentially malicious input could serve as a temporary mitigation.
