CVE-2026-65842Network attack vector

SSRF response disclosure via remote DOCX images

Published Aug 20, 2026 · Updated Aug 21, 2026

SSRF in Plate @platejs/docx-io before 53.3.2 allows remote attackers to read internal responses through generated DOCX files. The htmlToDocxBlob export path dereferences untrusted remote image URLs by default and embeds the returned bytes as document media. Exposure requires an application to convert attacker-controlled HTML in a server-side or privileged environment, enabling internal-response disclosure and resource consumption.
