CVE-2025-56589Public exploitNetwork attack vector

Server file disclosure and SSRF via iframe sources

Published Jan 22, 2026 · Updated Jan 22, 2026

SSRF and local file inclusion in Apryse HTML2PDF SDK 11.5.0, 11.7.0, and 11.10 allow remote attackers to read files or request URLs. InsertFromHtmlString passes unsanitized HTML to headless Chromium, which loads attacker-selected HTTP or file iframe sources and embeds the retrieved content in the generated PDF. Exploitation requires a consuming server application to accept attacker-controlled HTML and return the PDF; file access is bounded by the server process permissions and network reachability.
