The LazyLoad Plugin – Lazy Load Images, Videos, and Iframes for WordPress contains a stored cross-site scripting (XSS) vulnerability in the comment_content parameter. This affects all versions up to and including 2.4.0. The vulnerability arises from insufficient input sanitization and output escaping, allowing unauthenticated attackers to inject malicious scripts that execute when users view the affected pages. Exploitation requires a site administrator to approve the crafted comment before the payload is served to visitors.

The BackWPup WordPress plugin up to version 5.6.6 contains a path traversal vulnerability in the /wp-json/backwpup/v1/getblock REST endpoint via the block_name parameter. This flaw allows authenticated users with Administrator-level access or higher to include arbitrary PHP files on the server by exploiting insufficient sanitization of traversal sequences. This can lead to reading sensitive files like wp-config.php or potentially remote code execution depending on server configuration. Permissions granted to lower-level users to handle backups may also enable exploitation by those users. The vulnerability has a high severity score of 7.2 and no official patch or remediation guidance has been provided yet.

The BackWPup – WordPress Backup & Restore Plugin plugin for WordPress is vulnerable to unauthorized modification of data that can lead to privilege escalation due to a missing capability check on the save_site_option() function in all versions up to, and including, 5.6.2. This makes it possible for authenticated attackers, with level access and above, to update arbitrary options on the WordPress site. This can be leveraged to update the default role for registration to administrator and enable user registration for attackers to gain administrative user access to a vulnerable site.

The BackWPup – WordPress Backup & Restore Plugin plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'backwpup_working' AJAX action in all versions up to, and including, 5.5.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to retrieve access to a back-up's filename while a backup is running. This information has little value on it's own, but could be used to aid in a brute force attack to retrieve back-up contents in limited environments (i.e. NGINX).
