CVE-2025-13080Network attack vector

Page disruption via poisoned response caching

Published Nov 18, 2025 · Updated Nov 18, 2025

Cache poisoning in Drupal core allows remote attackers to disrupt page rendering and client-side functionality via crafted HTTP requests. An underlying library lets selected incoming request attributes be overridden, and Drupal consequently stores response data that should not be cached. No authentication or user interaction is required; poisoned entries can give legitimate requests broken, unstyled, or malformed pages.
