CVE-2026-122080 · Severity: info · Published 2026-11-04

The htmLawed Drupal module provides HTML filtering to prevent malicious content in user-submitted text. The module can be bypassed on sites using SQLite databases by submitting specially crafted UTF-8 characters, allowing attackers to inject and execute arbitrary JavaScript in the context of other users' browsers.

## Technical details

The htmLawed module's HTML filtering can be bypassed using malformed UTF-8 sequences on SQLite-backed sites running htmLawed library versions prior to 1.2.17. This allows stored XSS attack execution via injected malicious scripts in text input fields. The vulnerability only affects sites using SQLite databases with affected module versions.

## Affected products

- Drupal htmLawed >=3.0.0 <3.9.0 or >=4.0.0 <4.1.8
- htmLawed prior to 1.2.17
