CVE-2024-11941Network attack vector

Unauthenticated denial of service via comment replies

Published Dec 5, 2024 · Updated Dec 5, 2024

Denial of service in Drupal Core 10.1.0 through 10.1.7 and 10.2.0 through 10.2.1 allows remote attackers to interrupt sites. The Comment module's reply handling can enter an infinite loop and allocate resources excessively, but Drupal has not disclosed the triggering request shape or code path. The endpoint is network reachable without authentication, and only sites with the Comment module enabled are exposed; successful requests can make the site unavailable.
