Deeper analysis

The vulnerability is an SQL injection flaw, tracked as CVE-2023-1730 and assigned CWE-89, that affects the SupportCandy WordPress plugin prior to version 3.1.5. The plugin fails to validate or escape user-supplied input before incorporating it into SQL statements, producing a CVSS 3.1 base score of 9.8.

Unauthenticated remote attackers can exploit the issue over the network without any credentials or user interaction, allowing them to execute arbitrary SQL commands that may result in full compromise of the confidentiality, integrity, and availability of the affected WordPress site and its database.

The referenced WPScan advisory at https://wpscan.com/vulnerability/44b51a56-ff05-4d50-9327-fc9bab74d4b7 documents the flaw and indicates that updating to SupportCandy 3.1.5 or later eliminates the injection vector. The associated EPSS score has remained steady at 0.8180 since disclosure, indicating sustained but not newly emerging exploitation interest.
