Detailsinfo

A vulnerability, which was classified as problematic, has been found in Creative Interactive Media Real3D Flipbook Lite Plugin up to 5.1.1. Affected by this issue is the function on_shortcode of the component Shortcode Handler. The manipulation of the argument lightboxtext with an unknown input leads to a cross site scripting vulnerability. Using CWE to declare the problem leads to CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. Impacted is integrity. CVE summarizes:

The Real3D Flipbook Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'lightboxtext' shortcode attribute (and other unsanitized attributes handled by on_shortcode()) in versions up to, and including, 5.1.1. This is due to insufficient input sanitization and output escaping in the on_shortcode() and print_global_options() functions: shortcode attribute values are copied verbatim into $this->flipbook_options and then emitted via wp_json_encode() inside a <script type="application/json"> block without the JSON_HEX_TAG flag, allowing a literal </script> byte sequence in the attribute value to break out of the JSON script context. Because WordPress's shortcode_parse_atts() applies stripcslashes() to attribute values, an attacker can encode the breakout tag as \x3c/script\x3e\x3cscript\x3e…\x3c/script\x3e, which survives the wp_kses_post save-time filter applied to Contributor content (the escape bytes are safe text characters, not HTML tags) and is decoded to real angle brackets at render time. 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 (typically an Editor or Administrator previewing/moderating the pending post) accesses an injected page.

The advisory is available at wordfence.com. This vulnerability is handled as CVE-2026-15098 since 07/08/2026. The exploitation is known to be easy. The attack may be launched remotely.
