CVE-2026-33311 identifies a Cross-Site Scripting (XSS) vulnerability in the DiceBear avatar library, affecting versions 5.0.0 up to 9.4.0 (excluding patched versions). The flaw stems from unescaped user-supplied SVG attribute values, such as background and font colors, when interpolated into SVG output. Rated Medium with a CVSS score of 4.7 (AV:N/AC:H/UI:R), exploitation requires high attack complexity and user interaction, potentially leading to low impact on confidentiality and integrity. However, applications validating input against the library's JSON Schema or using the DiceBear CLI are not vulnerable. There is currently no evidence of active exploitation, public exploit code, or significant community discussion, with an extremely low EPSS score indicating minimal likelihood of exploitation.
