CVE-2026-115729 is a server-side request forgery (SSRF) vulnerability in the pdfme common library versions from 5.5.10 up to but not including 6.2.6. The flaw allows attackers to bypass the isUrlSafeToFetch denylist in the getB64BasePdf function by using specially crafted basePdf URLs with IPv4-mapped IPv6, [::], NAT64, or localhost alias hostnames. This enables reading of loopback, internal, or cloud metadata responses through generated PDF documents.
