Summary

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. This allows 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.

Risk Assessment

A subsite administrator can affect snippets running across the entire network, potentially leading to unauthorized code changes and possible malicious code execution. This breaks isolation between subsites.

Recommendation

Update the Code Snippets plugin to version 3.10.0 or later. Verify subsite administrator privileges and review active network-scoped snippets.

CVE-2026-106097Medium
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.
