CVE-2026-1592 is a stored cross-site scripting vulnerability in Foxit PDF Editor Cloud (pdfonline), specifically in the Create New Layer feature. The flaw is caused by inadequate sanitization and output encoding of user-supplied layer names before they are embedded into HTML output. An attacker with the ability to supply crafted layer content can store malicious script in a layer name so that arbitrary JavaScript executes in the victim’s browser when the affected layer is later referenced or rendered in the Layers panel. The issue affects Foxit PDF Editor Cloud instances prior to the February 3, 2026 fix.
