    DRUPAL-CONTRIB-2026-275

    Published: 28 Oct 2026Last Modified: 28 Oct 2026

    Summary:

    Details: Single Content Sync enables exporting and importing content, referenced entities, and files between Drupal sites. A maliciously crafted import file can cause untrusted data to be deserialized, potentially leading to remote code execution. This vulnerability is mitigated by the fact that an attacker must have a role with the "import single content" permission.
