HIGHPre-NVD 7.57.5—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 69% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

DiceBear is an avatar library for designers and developers. Prior to version 9.4.2, the ensureSize() function in @dicebear/converter used a regex-based approach to rewrite SVG width/height attributes, capping them at 2048px to prevent denial of service. This size capping could be bypassed by crafting SVG input that causes the regex to match a non-functional occurrence of before the actual SVG root element. When the SVG is subsequently rendered via @resvg/resvg-js on the Node.js code path, it renders at the attacker-specified dimensions, potentially causing out-of-memory crashes. In version 9.4.2, the regex-based approach has been replaced with XML-aware processing using fast-xml-parser to correctly identify and modify the SVG root element's attributes. Additionally, a fitTo constraint has been added to the renderAsync call as defense-in-depth, ensuring the rendered output is always bounded regardless of SVG content.
