Is hk_shortcode safe? Known vulnerabilities and latest version

Status: Closed 2026-05-19
Known issues on record: 1
Unpatched in latest: 0

What to do

Replace it. A closed plugin gets no updates through WordPress, so any hole found from now on stays open.
Deactivate and delete it once you have a replacement (Plugins → Deactivate → Delete). Deleting removes its files; deactivating alone leaves them on the server.
If you ran a vulnerable version and something looks off (spam pages, strange admins, redirects), run the free scan, or have us clean it: Emergency Cleanup, $499.

With WP-CLI, once you have a replacement: wp plugin deactivate hk-shortcode && wp plugin delete hk-shortcode

Stored cross-site scripting (XSS) in hk_shortcode (1.0 and older)

Affected: 1.0 and older
Fixed in: unknown

Range from: CVE record (the advisory publisher) · score by Wordfence

Details from the advisory

The hk_shortcode plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'title-plane' shortcode in versions up to, and including, 1.0. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes in the huankong_post_short_title_plane() function, where the 'title' attribute is concatenated directly into HTML output without any escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
