CVE-2026-18352: CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in gm_alex User Access Manager
The User Access Manager plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 2.3.15 via the 'uamgetfile' parameter parameter. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. This is possible because when attachment_url_to_postid() returns 0 for a traversal path, the plugin falls back to the global post set by a valid ?attachment_id parameter supplied by the attacker, causing the access check to pass against a legitimate public attachment while the file streamed is the attacker-chosen path.
AI Analysis
Technical Summary
CVE-2026-18352 is a directory traversal vulnerability (CWE-22) in the User Access Manager WordPress plugin (gm_alex) affecting all versions up to 2.3.15. The issue occurs via the 'uamgetfile' parameter, where the function attachment_url_to_postid() returns 0 for traversal paths, causing the plugin to fallback to a global post set by a valid ?attachment_id parameter supplied by the attacker. This fallback bypasses access controls by validating against a legitimate public attachment while streaming the attacker-chosen file path, allowing unauthorized file reads.
Potential Impact
An unauthenticated attacker can read arbitrary files on the server, potentially exposing sensitive information. The vulnerability does not allow modification or denial of service but compromises confidentiality.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch link is provided at this time. Until a patch is available, users should consider disabling the vulnerable plugin or restricting access to the 'uamgetfile' parameter if possible.
