# pdfmake: shared cache lets one PDF job read another's fetched resources

Link for people: https://infrastack.ai/live/CVE-2026-119743 (this .md is for agents)

pdfmake before 0.3.14 keeps a process-wide virtual file system keyed only by URL, so resources fetched for one document can be reused by a later document. An attacker who can make pdfmake render documents can read resources fetched with another caller's credentials or from URLs their own access policy would deny.

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

## How to check

- Check the installed pdfmake version with `npm ls pdfmake` or in the lockfile.
- Look for services that render untrusted or multi-tenant documents with pdfmake and fetch remote images or fonts by URL.

## Fix

- pdfmake: `0.3.14` or later (per the product advisory summary; the linked patch is not read here).

## From the sources

pdfmake before 0.3.14 contains a shared resource caching vulnerability that allows attackers to access cross-document cached resources by exploiting a process-wide virtual file system keyed only by URL without request headers or per-document access enforcement. Attackers can retrieve resources fetched with another caller's credentials or from URLs that a later document's access policy would deny, resulting in cross-document information disclosure and bypass of the URL access policy.
