CVE-2026-118548 · Severity: info · Published 2026-10-30

The Drupal AI module, which integrates artificial intelligence capabilities and provider interactions into websites, does not sufficiently validate links under certain conditions. This could allow attackers to redirect sensitive information to external sites. The risk is mitigated by the requirement that attackers must supply untrusted content that gets rendered as HTML by the module.

Technologies: [Drupal AI](https://junglewise.ai/threats/technologies/drupal-ai-1), [Packagist:Https://Packages.Drupal.Org/8 Drupal/Ai](https://junglewise.ai/threats/technologies/drupal-ai). Vendors: [Drupal](https://junglewise.ai/threats/vendors/drupal), [Packagist:Https://Packages.Drupal.Org/8](https://junglewise.ai/threats/vendors/packagist-https-packages-drupal-org-8).

## Technical details

The AI module fails to properly validate hyperlinks when processing HTML output under specific conditions, enabling information exfiltration via links to attacker-controlled external sites. This is a client-side or server-side rendering vulnerability in link sanitization logic. Exploitation requires an attacker to inject malicious content through untrusted data sources that the module then renders as HTML output.
