Unauthenticated file disclosure via unsanitized export HTML

Published May 15, 2026 · Updated May 15, 2026

Path traversal in DHTMLX PDF Export Module 0.3.3 through 0.7.5 allows remote attackers to read local server files via crafted HTML. The PDF export renderer accepts unsanitized HTML that can reference a local path and embeds the referenced file's contents in generated output. No authentication or user interaction is required; exposure is limited to files readable by the export service account.
