CVE-2026-8842

Descrição

The Google+ Link Name plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the -gplusnamelink- shortcode in versions up to, and including, 1.0. This is due to insufficient input sanitization and output escaping on user supplied attributes (-id- and -name-) in the gplusnamelink_generate() function, which are concatenated directly into the rendered HTML without calling esc_attr() or esc_html(). 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.
