Security readout for executives and security teams
Plain-English summary
CVE-2026-0749 is a cross-site scripting issue in the Drupal Form Builder module for Drupal 7. An attacker with some level of authenticated access could cause script execution in another user’s browser if user interaction occurs. The reported severity is medium, not currently listed as known exploited.
Executive priority
Treat this as a moderate-priority web application issue. It is not currently reported as actively exploited, but affected Drupal 7 sites with authenticated users should be reviewed and remediated through vendor guidance, especially where privileged users may interact with Form Builder content.
Technical view
The vulnerability is CWE-79 improper neutralization during web page generation. It affects Drupal Form Builder versions 7.x-1.0 through 7.x-1.22. CVSS 4.0 score is 4.8 with network attack vector, low complexity, low privileges required, and active user interaction required. Impact is limited to integrity in the vulnerable and subsequent systems.
Likely exposure
Exposure is likely limited to Drupal 7 sites that have the Form Builder module installed in versions 7.x-1.0 through 7.x-1.22. Sites not using this module, or outside the affected version range, are not indicated as affected by the supplied sources.
Exploitation context
The sources do not report active exploitation, and the CVE is not marked KEV. Exploitation requires an authenticated attacker and user interaction, which lowers urgency compared with unauthenticated XSS, but administrative users interacting with affected pages could increase business impact.
Researcher notes
Key constraints are PR:L and UI:A, with no confidentiality or availability impact in the CVSS vector. Public details in the supplied bundle identify the affected range but do not provide exploit mechanics. Avoid assuming a patch version unless confirmed in the linked advisories.
Mitigation direction
- Inventory Drupal 7 sites for the Form Builder module.
- Identify whether installed versions are 7.x-1.0 through 7.x-1.22.
- Review the linked vendor advisories for fixed-version or support guidance.
- Restrict access to Form Builder functionality to trusted users until remediated.
- Prioritize remediation for sites used by administrators or exposed to many authenticated users.
Validation and detection
- Confirm the module name and version from Drupal administration or asset inventory.
- Check whether affected sites match the CVE version range.
- Review user roles with access to Form Builder-related functionality.
- Verify remediation against the vendor advisory, not only scanner output.
- Monitor logs and reports for suspicious stored or reflected script behavior.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
