CVE-2025-13066: CWE-434 Unrestricted Upload of File with Dangerous Type in kraftplugins Demo Importer Plus
The Demo Importer Plus plugin for WordPress is vulnerable to arbitrary file upload in all versions up to, and including, 2.0.6. This is due to insufficient file type validation detecting WXR files, allowing double extension files to bypass sanitization while being accepted as a valid WXR file. This makes it possible for authenticated attackers, with author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
AI Analysis
Technical Summary
The Demo Importer Plus plugin for WordPress suffers from CWE-434: Unrestricted Upload of File with Dangerous Type. The vulnerability arises because the plugin inadequately validates uploaded WXR files, allowing files with double extensions to bypass checks. Authenticated attackers with author-level access or higher can exploit this to upload arbitrary files to the server, potentially leading to remote code execution. The CVSS 3.1 base score is 8.8, reflecting high impact on confidentiality, integrity, and availability with network attack vector and low attack complexity.
Potential Impact
Successful exploitation allows authenticated users with author-level or higher privileges to upload arbitrary files to the web server. This can lead to remote code execution, compromising the confidentiality, integrity, and availability of the affected WordPress site. The vulnerability poses a significant risk to site security and data protection.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is released, restrict author-level user permissions where possible and monitor for suspicious file uploads. Consider disabling or removing the Demo Importer Plus plugin if it is not essential to reduce exposure.
