CVE-2025-9552Network attack vector

Unauthenticated information disclosure

Published Oct 10, 2025 · Updated Oct 10, 2025

An undisclosed flaw in all versions of Drupal Synchronize composer.json With Contrib Modules allows remote attackers to read unspecified data. Drupal has not published the affected code path or the operation it performs incorrectly on untrusted input. Network access without authentication is sufficient, and the published assessment limits the consequence to confidentiality loss without data modification or service interruption.
