Deeper analysis
The WP SVG Icons WordPress plugin through version 3.2.3 contains an improper input validation flaw (CWE-434) that affects the handling of uploaded custom icon packs. The component fails to sanitize zip archives supplied through its administrative interface, permitting a high-privileged account to include executable PHP files within the archive.
An authenticated administrator can exploit the issue over the network by uploading a crafted zip containing malicious PHP code. Successful exploitation grants the attacker the ability to execute arbitrary code on the server, resulting in full confidentiality, integrity, and availability impact as reflected in the CVSS 7.2 rating.
The referenced WPScan advisory at https://wpscan.com/vulnerability/a30212a0-c910-4657-aee1-4a2d72c77983 documents the vulnerability but supplies no additional mitigation details beyond the published description. The associated EPSS score has remained flat at 0.1329 with no material increase since disclosure.
