Attackers can supply a crafted glTF or GLB file with large sparse indices to corrupt heap memory, crash applications, and potentially execute code when cgltf_validate() is not called.","published":"2026-10-18T11:38:38.538Z","modified":"2026-10-18T11:38:38.538Z","cvss":{"score":7,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://hackmd.io/@haindpwn/cgltf-accessor-unpack-floats-sparse-oob"},{"type":"WEB","url":"https://github.com/jkuhlmann/cgltf/blob/360db1a95480fe102ae9c69b27c5d101167ff5ba/cgltf.h#L2436-L2441"},{"type":"WEB","url":"https://github.com/jkuhlmann/cgltf"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/cgltf-through-1.15-heap-out-of-bounds-write-via-cgltf-accessor-unpack-floats"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-18T11:38:38.538Z"}}
