Description

The Ninja Tables WordPress plugin before 5.2.17 does not restrict shortcode expansion to administrator-authored table rows which, in a non-default configuration, allows unauthenticated users to have arbitrary shortcodes executed on a public page, and to permanently break that page, by submitting an ordinary form entry.
