The Migration, Backup, Staging – WPvivid plugin for WordPress is vulnerable to sensitive information disclosure of a WordPress site's database due to missing capability checks on the wp_ajax_wpvivid_add_remote AJAX action that allows low-level authenticated attackers to send back-ups to a remote location of their choice for review. 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.

The Duplicator plugin for WordPress is vulnerable to information exposure in all versions up to, and including, 1.5.9. This makes it possible for unauthenticated attackers to obtain the full path to instances, which they may be able to use in combination with other vulnerabilities or to simplify reconnaissance work. On its own, this information is of very limited use.

Missing Authorization vulnerability in WebToffee WordPress Backup & Migration.This issue affects WordPress Backup & Migration: from n/a through 1.4.3.

The WP STAGING WordPress Backup Plugin – Migration Backup Restore plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the wpstg_processing AJAX action in all versions up to, and including, 3.4.3. 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.

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.

The WordPress Backup & Migration plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the wp_mgdp_populate_popup function in all versions up to, and including, 1.4.8. This makes it possible for authenticated attackers, with subscriber access or above, to invoke this function and access log files maintained by the plugin. Additionally, the file name is user-provided and not properly sanitized, which allows attackers to read arbitrary log files on the file system.

The WP STAGING and WP STAGING Pro plugins for WordPress are vulnerable to Sensitive Information Exposure in versions up to, and including, 3.4.3, and versions up to, and including, 5.4.3, respectively, via the ajaxSendReport function. This makes it possible for unauthenticated attackers to extract sensitive data from a log file, including system information and (in the Pro version) license keys. Successful exploitation requires an administrator to have used the 'Contact Us' functionality along with the "Enable this option to automatically submit the log files." option.

Insertion of Sensitive Information into Log File vulnerability in Inisev Backup Migration.This issue affects Backup Migration: from n/a through 1.4.3.

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.
