Real-World Exposure
drupal/lightgalleryReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist:https://packages.drupal.org/8 packages — download data is not available via public APIs for these ecosystems.
Description
This module integrates Drupal with LightGallery, enabling the use of the LightGallery library with any image field or view.
The module does not adequately sanitize user input in the image field’s "alt" attribute, potentially allowing cross-site scripting (XSS) attacks when tags or scripts are inserted.
This vulnerability is partially mitigated by the requirement that an attacker must have permission to create content containing an image field configured to use the LightGallery format.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for drupal/lightgallery, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update drupal/lightgallery to 1.6.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-48447 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 CVE-2025-48447 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2025-48447. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
