- Severity: CVSS 6.3 (Medium), CNA

CVE-2026-119743 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 6.3 (medium) and affects pdfmake; fixed in 0.3.14.

## Summary

pdfmake versions before 0.3.14 can leak cached resources between documents, since the process-wide virtual file system is keyed only by URL and does not enforce per-document access. An attacker can reach this remotely, without logging in, and retrieve resources fetched with another caller's credentials or from URLs that a later document's access policy would deny.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- bpampuch pdfmake: from 0.3.0-beta.1, fixed in 0.3.14

## Description

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.
