CVE-2026-32845

CVE-2026-32845 is a medium-severity vulnerability rated 6.9/10 on the CVSS scale. 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.. EPSS estimates a 0.13% chance of exploitation in the next 30 days.
