Cross-Site Scripting (XSS) in GNTT Post Title Ticker (WordPress plugin) (CVE-2026-8701)
Summary
Cross-site scripting in GNTT Post Title Ticker (WordPress plugin) (CVE-2026-8701). Risk of unauthorized operations or information disclosure. Exploitable via border.
Original description
The description as published by the source.
The GNTT Post Title Ticker plugin for WordPress is vulnerable to Stored Cross-Site Scripting in version 1.0 via the title-ticker-slide, title-ticker-fade, and title-ticker-typing shortcodes. This is due to insufficient input sanitization and output escaping on shortcode attributes (notably border, width, height, header_background, header_text_color, and id) within the gntt_title_ticker_slide(), gntt_title_ticker_fade(), and gntt_title_ticker_typing() functions. None of these attribute values are passed through esc_attr() or any other escaping function before being concatenated into HTML output. 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.
