CVE-2021-24129

Estado: ModificadaMedia (5.4)—

Unvalidated input and lack of output encoding in the Themify Portfolio Post WordPress plugin, versions before 1.1.6, lead to Stored Cross-Site Scripting (XSS) vulnerabilities allowing low-privileged users (Contributor+) to inject arbitrary JavaScript code or HTML in posts where the Themify Custom Panel is embedded, which could lead to privilege escalation.
