CVE-2026-48094Public exploitNetwork attack vector

Cross-site scripting via unescaped sharing URL

Published Aug 7, 2026 · Updated Aug 7, 2026

Cross-site scripting in ShareOpenly before 1.2.1 allows remote attackers to execute browser script through an influenced sharing URL. The shareopenly_add_to_content function inserts the home_url result into a sharing-link href attribute without applying esc_url. Exploitation requires another plugin, theme, or hosting condition to make that URL attacker-influenced; visiting an affected page then executes injected script in the visitor's browser.
