Vulnerability in Bpampuch Pdfmake
CVE-2026-119743
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.
