See how updraftplus compares to other vendors in security performance
The UpdraftPlus: WP Backup & Migration Plugin WordPress plugin before 1.26.7 does not have CSRF checks in one of its backup management actions, which could allow attackers to make a logged in admin restore an existing backup, reverting the site's database and files to an earlier state, via a crafted link.
The WP-Optimize WordPress plugin before 4.2.0 does not properly escape user input when checking image compression statuses, which could allow users with the administrator role to conduct SQL Injection attacks in the context of Multi-Site WordPress configurations.
The UpdraftPlus: WP Backup & Migration Plugin plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the showdata and initiaterestore parameters in all versions up to, and including, 1.24.12 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 an admin user into performing an action such as clicking on a link.
The UpdraftPlus: WP Backup & Migration Plugin plugin for WordPress is vulnerable to PHP Object Injection in all versions from 1.23.8 to 1.24.11 via deserialization of untrusted input in the 'recursiveunserializedreplace' function. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present. An administrator must perform a search and replace action to trigger the exploit.
The All-In-One Security (AIOS) – Security and Firewall plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'tab' parameter in all versions up to, and including, 5.2.5 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.
The UpdraftPlus: WordPress Backup & Migration Plugin plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.23.10. This is due to a lack of nonce validation and insufficient validation of the instanceid on the 'updraftmethod-googledrive-auth' action used to update Google Drive remote storage location. This makes it possible for unauthenticated attackers to modify the Google Drive location that backups are sent to via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. This can make it possible for attackers to receive backups for a site which may contain sensitive information.
Unauth. Reflected Cross-Site Scripting (XSS) vulnerability in Paul Kehrer Updraft plugin <= 0.6.1 versions.
The WP-Optimize WordPress plugin before 3.2.13, SrbTransLatin WordPress plugin before 2.4.1 use a third-party library that removes the escaping on some HTML characters, leading to a cross-site scripting vulnerability.
Cross-Site Request Forgery (CSRF) vulnerability in UpdraftPlus.Com, DavidAnderson UpdraftPlus WordPress Backup Plugin <= 1.23.3 versions leads to sitewide Cross-Site Scripting (XSS).
The All-In-One Security (AIOS) WordPress plugin before 5.1.5 does not escape the content of log files before outputting it to the plugin admin page, allowing an authorized user (admin+) to plant bogus log files containing malicious JavaScript code that will be executed in the context of any administrator visiting this page.
The All-In-One Security (AIOS) WordPress plugin before 5.1.5 does not limit what log files to display in it's settings pages, allowing an authorized user (admin+) to view the contents of arbitrary files and list directories anywhere on the server (to which the web server has access). The plugin only displays the last 50 lines of the file.
The All-In-One Security (AIOS) WordPress plugin before 5.1.3 leaked settings of the plugin publicly, including the used email address.
The All-In-One Security (AIOS) WordPress plugin before 5.0.8 is susceptible to IP Spoofing attacks, which can lead to bypassed security features (like IP blocks, rate limiting, brute force protection, and more).
The UpdraftPlus WordPress Backup Plugin WordPress plugin before 1.22.9 does not sanitise and escape the updraftinterval parameter before outputting it back in an admin page, leading to a Reflected Cross-Site Scripting (XSS) vulnerability.
The UpdraftPlus WordPress plugin Free before 1.22.3 and Premium before 2.22.3 do not properly validate a user has the required privileges to access a backup's nonce identifier, which may allow any users with an account on the site (such as subscriber) to download the most recent site & database backup.
The UpdraftPlus WordPress Backup Plugin WordPress plugin before 1.16.69 does not sanitise and escape the updraftrestore parameter before outputting it back in the Restore page, leading to a Reflected Cross-Site Scripting
