CVE-2026-2358Network attack vector

Stored XSS via decoded shortcode template attribute

Published Mar 11, 2026 · Updated Mar 11, 2026

Stored XSS in Alimir WP ULike 5.0.1 and earlier allows remote authenticated users to inject scripts through a shortcode template attribute. The wp_ulike_likers_box shortcode applies html_entity_decode() to its template attribute after wp_kses_post() filtering, restoring encoded markup without output sanitization. Contributor-level access and a post with at least one like are required; viewing the crafted page executes the stored script in the visitor's browser.
