CVE-2024-29099Network attack vector

Script execution via reflected unsanitized input

Published Mar 19, 2024 · Updated Apr 28, 2026

Reflected XSS in Evergreen Content Poster 1.4.1 and earlier allows remote attackers to execute scripts through a crafted web request. Public advisories attribute the flaw to insufficient input sanitization and output escaping but do not identify the affected parameter or handler. Exploitation requires a user to follow an attacker-crafted request, after which the browser runs injected script in the affected WordPress site's security context.
