Description
@pdfme/common from 5.5.10 before 6.2.6 contains a server-side request forgery vulnerability that allows attackers to bypass the isUrlSafeToFetch denylist in getB64BasePdf. Attackers can supply basePdf URLs using IPv4-mapped IPv6, [::], NAT64 or localhost alias hostnames to read loopback, internal or cloud metadata responses through generated documents.
