How do I detect CVE-2025-31695 in my Packagist:https://packages.drupal.org/8 dependencies?

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

How do I mitigate CVE-2025-31695 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 CVE-2025-31695 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-31695 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 CVE-2025-31695?

Real-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 adds a formatter for link fields that displays the current entity with another view mode inside the link.

Drupal core does not sufficiently sanitize link element attributes, which can lead to a Cross Site Scripting vulnerability (XSS).

A separate fix for Drupal core has been released but this module requires a concurrent release to make use of the Drupal core fix.

This vulnerability is mitigated by that fact that an attacker would need to have the ability to add specific attributes to a Link field, which typically requires edit access via core web services, or a contrib or custom module.
