Description

@pdfme/common before 5.5.10 contains a server-side request forgery vulnerability in the getB64BasePdf function that fetches arbitrary URLs without validation when basePdf is attacker-controlled. Attackers who control the basePdf template field can force servers or clients to make requests to internal endpoints, enabling metadata exfiltration, network reconnaissance, and blind request forgery attacks.
