CVE-2026-1592Network attack vector

Stored XSS via unsanitized layer names

Published Feb 3, 2026 · Updated Feb 3, 2026

Stored XSS in Foxit PDF Editor Cloud before 2026-02-03 allows remote authenticated users to execute JavaScript via crafted layer names. The Create New Layer path stores a layer name and later embeds it into the Layers panel's HTML without adequate validation or output encoding. Low-privileged access is required to save the payload, and another user must open the affected Layers panel for it to run in that user's browser.
