WordPress vulnerability analysis and mitigation

CVE-2023-5712 affects the System Dashboard plugin for WordPress in versions up to and including 2.8.7. The vulnerability was disclosed on December 6, 2023, and stems from a missing capability check on the sd_global_value() function hooked via an AJAX action (NVD).

The vulnerability is classified as a Missing Authorization issue (CWE-862) with a CVSS v3.1 base score of 4.3 (Medium). The security flaw exists in the sd_global_value() function which lacks proper capability checks when accessed through AJAX actions.
