Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

This affects all versions of package node-pdf-generator. Due to lack of user input validation and sanitization done to the content given to node-pdf-generator, it is possible for an attacker to craft a url that will be passed to an external server allowing an SSRF attack.
