CVE-2026-68921Network attack vectorHinoki check available

Cross-site scripting via unescaped SVG attributes

Published Aug 20, 2026 · Updated Aug 20, 2026

Cross-site scripting in DiceBear before 9.4.3 allows attackers to execute script in a page origin via crafted SVG option values. In packages/@dicebear/core/src/utils/svg.ts, addRotate writes the rotate value into a transform attribute without XML escaping, and packages/@dicebear/initials/src/index.ts similarly emits fontSize and fontWeight into text attributes without escaping. Exploitation requires an application to pass untrusted data into these normally developer-controlled options and then render the SVG inline or open it as image/svg+xml, yielding script execution without a broader server-side compromise.
