Advisories for Npm/@Dicebear/Initials package

@dicebear/core builds avatar SVGs from caller-supplied options. The numeric rotate option is interpolated into an SVG transform attribute without XML-escaping. It is typed as a number, but nothing checks the type at runtime, so a string value passes straight through and can break out of the attribute to inject arbitrary SVG markup. This is the same root cause as CVE-2026-33311 (GHSA-mr9r-mww3-v6gv), which escaped the string options backgroundColor, fontFamily, and textColor …

SVG attribute values derived from user-supplied options (backgroundColor, fontFamily, textColor) were not XML-escaped before interpolation into SVG output. This could allow Cross-Site Scripting (XSS) when applications pass untrusted input to createAvatar() and serve the resulting SVG inline or with Content-Type: image/svg+xml.
