CVE-2025-14840Network attack vectorHinoki check available

Information disclosure via shared ECA result storage

Published Jan 28, 2026 · Updated Jan 28, 2026

Information disclosure in Drupal HTTP Client Manager before 9.3.13, 10.0.0 through 10.0.1, and 11.0.0 allows attackers to read HTTP results. ECA actions store command results under a shared last-result key, so parallel request operations can overwrite the value before a later action retrieves it. Exposure requires an administrator-configured ECA workflow with parallel HTTP actions and can reveal one request's response data to the wrong execution path.
