CVE-2026-3774

Sensitive-content disclosure via unprocessed script updates

Published Apr 1, 2026 · Updated Apr 1, 2026

Information disclosure in Foxit PDF Editor 2025.3 and earlier for Windows allows attackers to expose sensitive content via crafted PDFs. PDF JavaScript and WillPrint or DidPrint actions can update form fields, annotations, or optional content groups around redaction, encryption, or printing, but those workflows do not fully process the script-driven changes. A user must open and process a specially structured PDF; residual content can remain unredacted or unencrypted, or printed output can differ from the reviewed view.
