## Summary 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`. ## Affected packages - **`@dicebear/core`** — `backgroundColor` option values interpolated into SVG attributes without escaping (affects `solid` and `gradientLinear` background types) - **`@dicebear/initials`** — `fontFamily` and `textColor` option values interpolated into SVG attributes without escaping ## Fix All affected SVG attribute values are now properly escaped using XML entity encoding. Users should upgrade to the listed patched versions. ## Mitigating factors - Applications that validate input against the library's JSON Schema before passing it to `createAvatar()` are not affected - The DiceBear CLI validates input via AJV and was not vulnerable - Exploitation requires that an application passes untrusted, unvalidated external input directly as option values
