description

Unbounce Landing Pages versions through 1.1.6 are affected by a stored cross-site scripting flaw. An attacker could cause browser-side code to run for a visitor who opens a page containing malicious stored content.

mitigation

Review published landing pages and remove untrusted or suspicious content. Restrict page creation and editing to trusted users until Unbounce provides an update beyond 1.1.6.
