CVE-2026-32845: Jkuhlmann Cgltf

High severity, CVSS 8.4. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Jkuhlmann Cgltf: up to and including 1.15.0
