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."},{"lang":"es","value":"DiceBear es una biblioteca de avatares para diseñadores y desarrolladores. Antes de la versión 9.4.0, la función 'ensureSize()' en '@dicebear/converter' leía los atributos 'width' y 'height' del SVG de entrada para determinar el tamaño del lienzo de salida para la rasterización (PNG, JPEG, WebP, AVIF). Un atacante que pueda proporcionar un SVG manipulado con dimensiones extremadamente grandes (por ejemplo, 'width=\"999999999\"') podría forzar al servidor a asignar memoria excesiva, lo que llevaría a una denegación de servicio. Esto afecta principalmente a las aplicaciones del lado del servidor que pasan SVGs no confiables o proporcionados por el usuario a las funciones 'toPng()', 'toJpeg()', 'toWebp()' o 'toAvif()' del conversor. Las aplicaciones que solo convierten avatares DiceBear autogenerados no son prácticamente explotables, pero aún así se recomienda actualizarlas. Esto se ha solucionado en la versión 9.4.0. La función 'ensureSize()' ya no lee los atributos SVG para determinar el tamaño de salida. En su lugar, una nueva opción 'size' (predeterminado: 512, máximo: 2048) controla las dimensiones de salida. Los valores no válidos (NaN, negativo, cero, Infinito) vuelven al valor predeterminado. Si la actualización no es posible de inmediato, valide y sanee los atributos 'width' y 'height' de cualquier entrada SVG no confiable antes de pasarla al conversor."}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Primary","description":[{"lang":"en","value":"CWE-770"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:dicebear:dicebear:*:*:*:*:*:*:*:*","versionEndExcluding":"9.4.0","matchCriteriaId":"37C4F08A-FD88-4799-B9C7-85D60DB0FE0D"}]}]}],"references":[{"url":"https://github.com/dicebear/dicebear/commit/42a59eac46a3c68598859e608ec45e578b27614a","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/dicebear/dicebear/releases/tag/v9.4.0","source":"security-advisories@github.com","tags":["Product","Release Notes"]},{"url":"https://github.com/dicebear/dicebear/security/advisories/GHSA-v3r3-4qgc-vw66","source":"security-advisories@github.com","tags":["Mitigation","Vendor Advisory"]}]}}]}
