Live › vulnerability › CVE-2026-112018
Go to dashboardcgltf, a C library for loading glTF and GLB 3D model files, has an unchecked sparse accessor index in cgltf_accessor_unpack_floats() that writes past the output buffer. A crafted model file can crash the application or potentially run code when the caller does not call cgltf_validate() first.

Applications that embed cgltf through 1.15 and load untrusted glTF or GLB files, such as viewers, converters or asset pipelines that accept uploads. The sources do not say which builds or versions beyond 1.15 are unaffected, and whether calling cgltf_validate() fully prevents the issue is not stated in the sources. Applications that only load trusted, locally authored models are less exposed.

Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
cgltf through 1.15 contains a heap out-of-bounds write vulnerability in cgltf_accessor_unpack_floats() 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 applications, and potentially execute code when cgltf_validate() is not called.
