Versions of the package pdfmake from 0.3.0-beta.1 and before 0.3.0-beta.17 are vulnerable to Allocation of Resources Without Limits or Throttling via repeatedly redirect URL in file embedding. An attacker can cause the application to crash or become unresponsive by providing crafted input that triggers this condition.

An issue discovered in pdfmake 0.2.9 allows remote attackers to run arbitrary code via crafted POST request to the /pdf endpoint. NOTE: this is disputed because the behavior of the /pdf endpoint is intentional. The /pdf endpoint is only available after installing a test framework (that lives outside of the pdfmake applicaton). Anyone installing this is responsible for ensuring that it is only available to authorized testers.
