2.3.7
CVE-2025-71282 addresses a vulnerability in XenForo versions 2.3.0 through 2.3.7 that allows attackers to disclose filesystem paths. The vulnerability arises from improper handling of exception messages when open_basedir restrictions are in place. By triggering specific error conditions, an attacker can obtain information about the server's directory structure.
The primary impact of CVE-2025-71282 is information disclosure. An attacker can leverage this vulnerability to map the server's filesystem, potentially identifying sensitive files and directories. While this vulnerability doesn't directly lead to code execution or data breaches, the gained information can be used to plan further attacks, such as privilege escalation or targeted file access. The blast radius includes all XenForo installations running the affected versions.
CVE-2025-71282 was published on 2026-04-01. Its presence on KEV or EPSS is unknown. Public proof-of-concept (POC) code is likely available given the nature of the vulnerability. Active campaigns targeting this vulnerability have not been reported, but the ease of exploitation makes it a potential target.
Organizations running XenForo forums, particularly those with custom plugins or extensions, are at risk. Shared hosting environments where multiple XenForo instances share the same server are also particularly vulnerable, as a compromise of one instance could potentially reveal information about other instances.
• php / web:
curl -I https://example.com/index.php?error_trigger=1 2>&1 | grep -i 'document_root'• php / web: Examine XenForo error logs for patterns revealing filesystem paths, such as /var/www/html/ or /opt/xenforo/.
• generic web: Review access logs for requests that trigger exceptions and analyze the corresponding error messages for directory path disclosures.

The primary mitigation for CVE-2025-71282 is to upgrade to XenForo version 2.3.7 or later. This version includes a fix that prevents the disclosure of filesystem paths. If an immediate upgrade is not possible, consider implementing stricter open_basedir restrictions to limit the potential impact of the vulnerability. Monitor XenForo error logs for unusual activity that might indicate exploitation attempts. After upgrading, confirm the fix by attempting to trigger the vulnerability and verifying that filesystem paths are no longer disclosed in error messages.
