CVE-2026-47360: Apache HTTP Server session cookie exposure in mod_session_cookie

CVE-2026-47360 · Severity: high · CVSS 7.5 · Published 2026-10-01

Apache HTTP Server's mod_session_cookie module can leak session cookies to backend servers when the SessionCookieRemove setting changes during internal request redirects. An attacker who controls a backend server or can intercept traffic could capture and reuse these session cookies to hijack authenticated user sessions.

Technologies: Apache HTTP Server. Vendors: Apache.

Technical details

A logic flaw in mod_session_cookie fails to remove session cookies when the SessionCookieRemove directive changes value across internal redirects, causing cookies marked for removal to still be forwarded to backend servers. This occurs without user interaction and affects any deployment where SessionCookieRemove is conditionally configured. A fix exists in Apache HTTP Server 2.4.69.
