CVE-2026-29112 is a Denial of Service (DoS) vulnerability affecting the DiceBear avatar library, specifically versions prior to 9.4.0 of the @dicebear/converter component. An attacker can exploit this by providing a crafted SVG with excessively large dimensions, forcing the server to allocate vast amounts of memory and causing a service disruption. Rated 7.5 HIGH (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), this vulnerability has a network-based attack vector and low complexity, primarily impacting server-side applications processing untrusted SVGs. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE. The vulnerability is resolved in version 9.4.0, which implements a controlled output size mechanism instead of relying on potentially malicious SVG attributes.
