FKIE_CVE-2026-4280

Vulnerability from fkie_nvd - Published: 2026-04-22 09:16 - Updated: 2026-04-22 20:22
Severity ?
6.5 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Summary
The Breaking News WP plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 1.3. This is due to the brnwp_ajax_form AJAX endpoint lacking both authorization checks and CSRF verification, combined with insufficient path validation when the brnwp_theme option value is passed directly to an include() statement in the brnwp_show_breaking_news_wp() shortcode handler. While sanitize_text_field() is applied to user input, it does not strip directory traversal sequences (../). This makes it possible for authenticated attackers, with Subscriber-level access and above, to overwrite the brnwp_theme option with a directory traversal payload (e.g., ../../../../etc/passwd) and subsequently trigger file inclusion of arbitrary files on the server when the shortcode is rendered.
