SCA: security update for @dicebear/converter (GHSA-v3r3-4qgc-vw66)

high Tenable Self-Hosted Container Security Plugin ID 438835

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - DiceBear is an avatar library for designers and developers. Prior to version 9.4.0, the `ensureSize()`
 function in `@dicebear/converter` read the `width` and `height` attributes from the input SVG to determine
 the output canvas size for rasterization (PNG, JPEG, WebP, AVIF). An attacker who can supply a crafted SVG
 with extremely large dimensions (e.g. `width="999999999"`) could force the server to allocate excessive
 memory, leading to denial of service. This primarily affects server-side applications that pass untrusted
 or user-supplied SVGs to the converter's `toPng()`, `toJpeg()`, `toWebp()`, or `toAvif()` functions.
 Applications that only convert self-generated DiceBear avatars are not practically exploitable, but are
 still recommended to upgrade. This is fixed in version 9.4.0. The `ensureSize()` function no longer reads
 SVG attributes to determine output size. Instead, a new `size` option (default: 512, max: 2048) controls
 the output dimensions. Invalid values (NaN, negative, zero, Infinity) fall back to the default. If
 upgrading is not immediately possible, validate and sanitize the `width` and `height` attributes of any
 untrusted SVG input before passing it to the converter. (CVE-2026-29112)

Solution

Update the @dicebear/converter library and its related packages to version 9.4.0 or later.
