Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-862.

Summary

The Code Snippets WordPress plugin before 3.10.0 does not perform a capability check on one of its snippet-management actions (CWE-862, Missing Authorization) and derives the network scope of the targeted snippet from the request instead of the stored record. An administrator of a single subsite on a multisite network can activate, deactivate and reprioritise network-scoped snippets that run across every site in the network. The CVSS vector requires high privileges and high attack complexity. CISA has not added it to KEV, and the references include an exploit link.
