# Foxit website HTML-to-PDF service: ZIP input bypasses internal address restrictions

Foxit's hosted HTML-to-PDF conversion service on its official website accepts ZIP-formatted input that gets past its block on requests to internal IP addresses. An attacker can use the service to probe internal network resources.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

Nothing to check: this is Foxit's hosted website service, not installed software. Only matters if you built integrations that send input to Foxit's online HTML-to-PDF converter; no version applies.

## Fix

Fixed by Foxit on its hosted online HTML-to-PDF service; no customer action required (Foxit bulletin 2026-10-29).

- 2026-10-29T10:26:17+00:00 analyst — Foxit bulletin (2026-10-29) says online HTML-to-PDF SSRF fixed server-side, no customer action; lists no self-hosted product. Sibling CVEs 111417/111419 same bulletin. No exploitation or PoC found.

## From the sources

A server-side request forgery (SSRF) vulnerability exists in the Foxit official website’s HTML-to-PDF conversion service. Support for ZIP-formatted input can bypass restrictions on requests to internal IP addresses, potentially allowing discovery of internal network resources.
