CVE-2025-71280

Local information disclosure via cached account pages

Published Apr 1, 2026 · Updated Apr 1, 2026

Information disclosure in XenForo before 2.3.7 allows local users to read cached account pages on shared systems. Account pages containing sensitive user information remain in a shared browser or machine cache that a subsequent local user can access. Reachability requires another user to access the same browser or machine, and exposure is limited to sensitive information retained from the earlier account session.
