@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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.29%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
