Is Code Snippets safe? Known vulnerabilities and latest version

The Code Snippets WordPress plugin before 3.10.0 does not perform a capability check on one of its snippet-management actions and derives the network scope of the targeted snippet from the request instead of from the stored record, allowing an administrator of a single subsite on a multisite network to activate, deactivate and reprioritise network-scoped snippets that run across every site in the network.

The Code Snippets WordPress plugin before 3.10.0 does not sanitise and escape a user-supplied parameter before using it in a SQL query in some of its snippet-migration import endpoints, which are accessible to any user holding site-administration capabilities; on a WordPress Multisite network those belong to subsite Administrators, allowing a subsite Administrator who is not a network Super Admin to perform UNION-based SQL injection against shared network tables and disclose network-wide data such as other users' password hashes.

The Code Snippets plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.9.4. This is due to missing nonce validation on the cloud snippet download and update actions in the Cloud_Search_List_Table class. This makes it possible for unauthenticated attackers to force logged-in administrators to download or update cloud snippets without their consent via a crafted request, granted they can trick an administrator into visiting a malicious page.

The Code Snippets plugin for WordPress is vulnerable to PHP Code Injection in all versions up to, and including, 3.9.1. This is due to the plugin's use of extract() on attacker-controlled shortcode attributes within the `evaluate_shortcode_from_flat_file` method, which can be used to overwrite the `$filepath` variable and subsequently passed to require_once. This makes it possible for authenticated attackers, with Contributor-level access and above, to execute arbitrary PHP code on the server via the `[code_snippet]` shortcode using PHP filter chains granted they can trick an administrator into enabling the "Enable file-based execution" setting and creating at least one active Content snippet.
