CVE-2026-10200Public exploit

Importer crash via unchecked glTF matrix length

Published May 31, 2026 · Updated May 31, 2026

Heap-buffer overflow in Assimp 6.0.0 through 6.0.4 allows local users to crash an importer with a malformed glTF2 file. In glTFCommon::CopyValue, the importer copies 16 floats from inverseBindMatrices data without first checking that the accessor supplies 64 bytes. A crafted local glTF2 file can make the 64-byte read overrun a one-byte heap allocation, causing an immediate process crash and an out-of-bounds memory read.
