On Sept. 17, CISA and FBI released a Secure by Design Alert, Eliminating Cross-Site Scripting Vulnerabilities, as a part of their ongoing effort to reduce the prevalence of vulnerability classes at scale. Vulnerabilities like cross-site scripting (XSS) continue to appear in software, enabling threat actors to exploit them. However, cross-site scripting vulnerabilities are preventable and should not be present in software products.

CISA and FBI urge CEOs and other business leaders at technology manufacturers to direct their technical leaders/teams to review past instances of these defects and create a strategic plan to prevent them in the future.
