CVE-2022-25273Network attack vector

Sensitive data overwrite via unvalidated form values

Published Apr 26, 2023 · Updated Feb 3, 2025

Improper input validation in Drupal core 8.0.0 through 9.2.17 and 9.3.0 through 9.3.11 allows remote attackers to overwrite data. Drupal has not identified the affected Form API routine; the API accepts submitted values that certain contributed or custom forms should reject, enabling field overwrites. Exposure requires an uncommon contributed or custom form with the affected input-handling pattern; Drupal reports no affected form in core itself.
