    CVE-2026-32845 (GCVE-0-2026-32845)

    Vulnerability from nvd – Published: 2026-03-23 15:50 – Updated: 2026-06-23 16:15

    Title
    jkuhlmann / cgltf <= 1.15 Sparse Accessor Validation Integer Overflow
    Summary
    cgltf version 1.15 and prior contain an integer overflow vulnerability in the cgltf_validate() 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 unchecked arithmetic operations in sparse accessor validation to cause heap buffer over-reads in cgltf_calc_index_bound(), resulting in denial of service crashes and potential memory disclosure.
