CVE-2025-71282 is an information disclosure vulnerability in XenForo forum software versions prior to 2.3.7. The issue arises when open_basedir restrictions trigger exception messages that inadvertently reveal filesystem paths, allowing attackers to enumerate the server's directory structure. Classified under CWE-209 (Generation of Error Message Containing Sensitive Information), it carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high confidentiality impact with network accessibility and no authentication required.

An unauthenticated attacker can exploit this vulnerability remotely by crafting requests that trigger open_basedir-protected operations, such as accessing restricted files or directories. Successful exploitation yields detailed server filesystem paths from error messages, which can aid in further reconnaissance for targeted attacks, such as identifying configuration files, backups, or other sensitive locations. No privileges, user interaction, or special conditions are needed, making it straightforward for automated scanning tools to detect and leverage.

XenForo's official release notes for version 2.3.7 confirm this as one of several security fixes, recommending immediate upgrades for affected installations. The Vulncheck advisory details the exception handling flaw and emphasizes patching to 2.3.7 or later, along with reviewing server logs for prior exploitation attempts, as no workarounds are provided beyond disabling verbose error reporting where feasible.
