    DRUPAL-CONTRIB-2026-190 (CVE-2026-96386)

    Vulnerability from drupal – Published: 2026-09-23 17:23 – Updated: 2026-09-23 17:27 – Source website
    VLAI
    Details

    This module enables you to personalize content for anonymous and authenticated users by showing different blocks to visitors based on client-side conditions.

    The Smart Content Block submodule doesn't sufficiently check block access when it renders the blocks of a "Display Blocks" reaction through the module's AJAX endpoint.

    This vulnerability is mitigated by the fact that a site must have placed a block whose access is restricted to certain users inside a Display Blocks reaction. Sites that only use Views blocks in reactions are not affected, because Views re-checks access when the view is executed.
