CVSS 5.4 (medium) · published 2026-10-29

Multiple Pages Generator by Themeisle before 4.2.5 contains a stored cross-site scripting vulnerability that allows Contributor-level users to inject script via the [mpg] and [mpg_match] shortcode base-url attribute. Attackers can store entity-encoded payloads that pass kses but are decoded by html_entity_decode() and rendered unescaped through {{mpg_url}}, executing script in administrators' browsers.
