The Photo Gallery by 10Web – Mobile-Friendly Image Gallery plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 1.8.23 via the esc_dir function. This makes it possible for authenticated attackers to cut and paste (copy) the contents of arbitrary files on the server, which can contain sensitive information, and to cut (delete) arbitrary directories, including the root WordPress directory. By default this can be exploited by administrators only. In the premium version of the plugin, administrators can give gallery edit permissions to lower level users, which might make this exploitable by users as low as contributors.

The Photo Gallery by 10Web – Mobile-Friendly Image Gallery plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘svg’ parameter in all versions up to, and including, 1.8.23 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. By default, this can only be exploited by administrators, but the ability to use and configure Photo Gallery can be extended to contributors on pro versions of the plugin.

The Photo Gallery by 10Web – Mobile-Friendly Image Gallery plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 1.8.19 via the rename_item function. This makes it possible for authenticated attackers to rename arbitrary files on the server. This can lead to site takeovers if the wp-config.php file of a site can be renamed. By default this can be exploited by administrators only. In the premium version of the plugin, administrators can give gallery management permissions to lower level users, which might make this exploitable by users as low as contributors.

The Photo Gallery by 10Web plugin for WordPress is vulnerable to Stored Cross-Site Scripting via widgets in versions up to, and including, 1.8.18 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with administrator-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. It can also be exploited with a contributor-level permission with a page builder plugin.

- The Photo Gallery by 10Web WordPress plugin before 1.8.15 did not ensure that uploaded files are kept inside its uploads folder, allowing high privilege users to put images anywhere in the filesystem via a path traversal vector.
