    CVE-2026-12108 (GCVE-0-2026-12108)

    Vulnerability from nvd – Published: 2026-07-10 07:48 – Updated: 2026-07-10 18:15

    Title
    Highlighting Code Block <= 2.2.0 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'font_family' Setting
    Summary
    The Highlighting Code Block plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 2.2.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
