Deeper analysis

The CVE-2022-1556 vulnerability is an SQL injection flaw in the StaffList WordPress plugin before version 3.1.5. It arises because the plugin fails to properly sanitize and escape a parameter before incorporating it into a SQL statement during staff searches performed in the administrative dashboard, corresponding to CWE-89 and carrying a CVSS 3.1 score of 9.8.

Unauthenticated attackers can exploit the flaw remotely over the network with low attack complexity and without requiring user interaction, enabling them to execute arbitrary SQL commands that may result in full compromise of confidentiality, integrity, and availability on the affected WordPress installation.

Public advisories and proof-of-concept material are published at WPScan and Packet Storm Security, which identify the root cause in the pre-3.1.5 code and point to the availability of a fixed release. The associated EPSS score has remained flat at a peak of 0.0883 since disclosure.
