CVE-2026-112018

cgltf through 1.15 contains a heap out-of-bounds write vulnerability in cgltfaccessorunpackfloats that allows attackers to write outside the output buffer via unchecked sparse accessor indices. Attackers can supply a crafted glTF or GLB file with large sparse indices to corrupt heap memory, crash...

EUVD-2026-14448

cgltf version 1.15 and prior contain an integer overflow vulnerability in the cgltfvalidate function when validating sparse accessors that allows attackers to trigger out-of-bounds reads by supplying crafted glTF/GLB input files with attacker-controlled size values. Attackers can exploit unchecke...

CGLTF security vulnerabilities

CGLTF is a library developed by Johannes Kuhlmann from Germany, used for loading and processing GLTF 3D model formats. Versions of CGLTF prior to 1.15 contained security vulnerabilities. These vulnerabilities stemmed from integer overflows in the cgltfvalidate function during the validation of...
