CVE-2025-5961: CWE-434 Unrestricted Upload of File with Dangerous Type in wpvividplugins WPvivid — Backup, Migration & Staging
The Migration, Backup, Staging – WPvivid Backup & Migration plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'wpvivid_upload_import_files' function in all versions up to, and including, 0.9.116. This makes it possible for authenticated attackers, with Administrator-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. NOTE: Uploaded files are only accessible on WordPress instances running on the NGINX web server as the existing .htaccess within the target file upload folder prevents access on Apache servers.
AI Analysis
Technical Summary
The WPvivid Backup, Migration & Staging plugin for WordPress suffers from CWE-434: Unrestricted Upload of File with Dangerous Type. The vulnerability arises from insufficient validation of file types in the 'wpvivid_upload_import_files' function, enabling authenticated administrators to upload arbitrary files to the server. This flaw is present in all versions up to and including 0.9.116. Uploaded files can be accessed and potentially executed on WordPress instances running on NGINX, as Apache servers use .htaccess to block access to the upload directory. The CVSS 3.1 base score is 7.2, reflecting high impact on confidentiality, integrity, and availability. No patch or official fix is currently documented.
Potential Impact
An attacker with Administrator privileges can upload arbitrary files to the server, potentially leading to remote code execution on NGINX-hosted WordPress sites. This compromises the confidentiality, integrity, and availability of the affected system. Apache-hosted sites are less impacted due to .htaccess restrictions preventing access to uploaded files. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Administrator access to trusted users only and consider disabling or limiting the use of the vulnerable plugin. Monitor for updates from the vendor and apply patches promptly once released.
