Vulnerabilities

CVE-2025-5961 is an arbitrary file upload vulnerability (CWE-434) in the Migration, Backup, Staging - WPvivid Backup & Migration plugin for WordPress, caused by missing file type validation in the 'wpvivid_upload_import_files' function in all versions up to and including 0.9.116. An authenticated attacker with Administrator-level access or higher can upload arbitrary files of any type to the affected server, and uploaded files are only web-accessible when the site runs on NGINX because the existing .htaccess in the upload folder blocks direct access on Apache. By uploading a web-executable file such as a PHP script, the attacker can achieve remote code execution on the site's server (CVSS 3.1: 7.2 High). Any WordPress site running WPvivid Backup & Migration at or below 0.9.116 is affected, but only NGINX-hosted sites are exploitable for remote code execution via this path. The flaw is not yet in CISA KEV; however, two public proof-of-concept exploits are available and EPSS assigns a 57.6% probability of exploitation within 30 days (99th percentile), so near-term in-the-wild use is plausible.

Do: Update WPvivid Backup & Migration to a release newer than 0.9.116 (the latest patched version) as soon as possible; Apache-hosted sites are shielded by the upload folder's .htaccess but should still update. Because exploitation requires Administrator-level credentials, review admin account activity, remove untrusted administrator accounts, and on NGINX-hosted sites inspect the plugin's upload folder for unexpected executable files such as .php.

The Migration, Backup, Staging – WPvivid Backup & Migration plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'upload_files' function in all versions up to, and including, 0.9.112. 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.

Missing Authorization vulnerability in wpvividplugins WPvivid Backup and Migration wpvivid-backuprestore allows Accessing Functionality Not Properly Constrained by ACLs.This issue affects WPvivid Backup and Migration: from n/a through <= 0.9.106.

The Migration, Backup, Staging – WPvivid plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 0.9.107 via deserialization of untrusted input in the 'replace_row_data' and 'replace_serialize_data' functions. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code. An administrator must create a staging site to trigger the exploit.

The Migration, Backup, Staging – WPvivid plugin for WordPress is vulnerable to arbitrary file uploads due to a missing capability check on the wpvivid_upload_import_files and wpvivid_upload_files AJAX actions that allows low-level authenticated attackers to upload zip files that can be subsequently extracted. This affects versions up to, and including 0.9.35.

The Migration, Backup, Staging WordPress plugin before 0.9.106 does not use sufficient randomness in the filename that is created when generating a backup, which could be bruteforced by attackers to leak sensitive information about said backups.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in wpvividplugins WPvivid Backup for MainWP wpvivid-backup-mainwp allows Reflected XSS.This issue affects WPvivid Backup for MainWP: from n/a through <= 0.9.32.

Improper Privilege Management vulnerability in WPvivid Team WPvivid Backup and Migration allows Privilege Escalation.This issue affects WPvivid Backup and Migration: from n/a through 0.9.90.

WPvivid Backup & Migration Plugin for WordPress is vulnerable to PHAR Deserialization in all versions up to, and including, 0.9.99 via deserialization of untrusted input at the wpvividstg_get_custom_exclude_path_free action. This is due to the plugin not providing sufficient path validation on the tree_node[node][id] parameter. This makes it possible for authenticated attackers, with admin-level access and above, to call files using a PHAR wrapper that will deserialize the data and call arbitrary PHP Objects. No POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

The WPvivid Backup for MainWP plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'id' parameter in all versions up to, and including, 0.9.32 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. CVE-2024-35664 is likely a duplicate of this issue.

The Migration, Backup, Staging – WPvivid plugin for WordPress is vulnerable to SQL Injection via the 'table_prefix' parameter in version 0.9.68 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The WPvivid plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the restore() and get_restore_progress() function in versions up to, and including, 0.9.94. This makes it possible for unauthenticated attackers to invoke these functions and obtain full file paths if they have access to a back-up ID.

The Migration, Backup, Staging - WPvivid plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 0.9.91 via Google Drive API secrets stored in plaintext in the publicly visible plugin source. This could allow unauthenticated attackers to impersonate the WPVivid Google Drive account via the API if they can trick a user into reauthenticating via another vulnerability or social engineering.

The Migration, Backup, Staging WordPress plugin before 0.9.76 does not sanitise and validate a parameter before using it to read the content of a file, allowing high privilege users to read any file from the web server via a Traversal attack

The Migration, Backup, Staging – WPvivid plugin for WordPress is vulnerable to deserialization of untrusted input via the 'path' parameter in versions up to, and including 0.9.74. This makes it possible for authenticated attackers with administrative privileges to call files using a PHAR wrapper that will deserialize and call arbitrary PHP Objects that can be used to perform a variety of malicious actions granted a POP chain is also present. It also requires that the attacker is successful in uploading a file with the serialized payload.

Arbitrary File Read vulnerability in WPvivid Team Migration, Backup, Staging – WPvivid (WordPress plugin) versions <= 0.9.70

The Migration, Backup, Staging WordPress plugin before 0.9.69 does not have authorisation when adding remote storages, and does not sanitise as well as escape a parameter from such unauthenticated requests before outputting it in admin page, leading to a Stored Cross-Site Scripting issue
