CVE-2026-96039Network attack vector

Unauthenticated script execution via unsanitized first_name

Published Sep 25, 2026 · Updated Sep 25, 2026

Stored cross-site scripting in Booking Algorithms BA Book Everything 1.8.27 and earlier allows remote attackers to execute scripts via first_name. The action_to_pay() handler accepts a guest order's first_name value without sufficient input sanitization or output escaping, causing stored markup to run when the injected page is viewed. A public guest booking exposes the required order_id, order_num, and order_hash values, so no account is required; execution occurs in the viewing user's browser.
