Stored XSS via unescaped post-type labels

Published Jan 16, 2023 · Updated Apr 4, 2025

Stored XSS in WordPress Creation Kit before 2.3.3 allows remote authenticated users to execute scripts in administrators' browsers. The post-type and taxonomy editors store Singular Label and Plural Label values without sanitizing or escaping them before rendering the labels in WordPress administration pages. Administrator access is required, and exploitation remains possible where WordPress disallows unfiltered HTML, including multisite installations.
