Drupal Cross-Site Scripting (XSS) affecting CKEditor Third-party library
Real-World Exposure
drupal/drupal🐘drupal/drupal🐘drupal/drupalReal-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 Drupal project uses the CKEditor, library for WYSIWYG editing. CKEditor has released a security update that impacts Drupal.
Vulnerabilities are possible if Drupal is configured to allow use of the CKEditor library for WYSIWYG editing. An attacker that can create or edit content (even without access to CKEditor themselves) may be able to exploit one or more Cross-Site Scripting (XSS) vulnerabilities to target users with access to the WYSIWYG CKEditor, including site admins with privileged access.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for drupal/drupal, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update drupal/drupal to 8.9.16 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qf65-hph9-453r is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-qf65-hph9-453r can be triaged on real exposure rather than presence alone.
Tailored to GHSA-qf65-hph9-453r. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-qf65-hph9-453r in your dependencies?
O3 Security finds GHSA-qf65-hph9-453r across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
