CVE-2025-10929Network attack vector

Unauthenticated access bypass via spoofed client IP

Published Oct 29, 2025 · Updated Oct 29, 2025

Access bypass in Drupal Reverse Proxy Header before 1.1.2 allows remote attackers to spoof the client IP through a crafted HTTP header. The module's request handling replaces Drupal's client IP with the configured header value without consistently enforcing configured trusted-proxy addresses. Exposure requires reverse_proxy enabled, reverse_proxy_header set, and reverse_proxy_addresses configured, and the false address can bypass IP-based controls.
