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.

Exploit prediction

2.04% chance of exploitation in the next 30 days, higher than 81% of all scored CVEs (FIRST EPSS, 2026-11-08).
