What is CVE-2026-8702?
CVE-2026-8702 is a medium-severity cross-site scripting vulnerability in garber GBI To Print, published on 27 May 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
The GBI To Print plugin for WordPress is vulnerable to Stored Cross-Site Scripting in version 1.0 via the 'div' attribute of the 'gbitoprint' shortcode. This is due to insufficient output escaping in the gbi_toprint_shortcode() function, which concatenates the raw shortcode attribute value directly into an HTML attribute without applying esc_attr() or any other sanitization. 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.
Weakness: CWE-79
