{"cve":"CVE-2026-29112","nvd":{"published":"2026-03-18T04:17:16.037","modified":"2026-06-17T10:29:37.180","status":"Analyzed","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-770"],"references":["https://github.com/dicebear/dicebear/commit/42a59eac46a3c68598859e608ec45e578b27614a","https://github.com/dicebear/dicebear/releases/tag/v9.4.0","https://github.com/dicebear/dicebear/security/advisories/GHSA-v3r3-4qgc-vw66"],"products":["dicebear:dicebear"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-29112","score":0.00352,"percentile":0.28868,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-v3r3-4qgc-vw66","url":"https://osv.dev/vulnerability/GHSA-v3r3-4qgc-vw66","summary":"Uncontrolled memory allocation via crafted SVG dimensions in @dicebear/converter","modified":"2026-03-19T21:17:23.205733Z","packages":[{"ecosystem":"npm","name":"@dicebear/converter","purl":"pkg:npm/%40dicebear/converter","ranges":["<9.4.0"],"fixed":["9.4.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
