CVE-2026-10230

A buffer overflow vulnerability was found in the Assimp library up to version 6.0.2 in the FBX Importer. The issue occurs in aiMaterial::AddBinaryProperty, where a property key string from a crafted FBX file is copied into a fixed-size heap buffer using strcpy() without runtime length validation.

A vulnerability has been detected in the Assimp library (Open Asset Import Library) version 17c12da. The issue affects the function Assimp::MDLImporter::ParseBoneTrafoKeys_3DGS_MDL7 in file code/AssetLib/MDL/MDLLoader.cpp, where manipulation of arguments transmatrix_count/pcBoneTransforms leads to buffer overflow. The attack can be initiated remotely, and the exploit is publicly available.

A vulnerability was detected in Open Asset Import Library Assimp 17c12da. This affects the function Assimp::MDLImporter::AddBonesToNodeGraph_3DGS_MDL7 of the file code/AssetLib/MDL/MDLLoader.cpp of the component Node Parser. The manipulation of the argument bones_num results in heap-based buffer overflow. The attack can be executed remotely. The exploit is now public and may be used. The project was informed of the problem early through an issue report but has not responded yet.

A security vulnerability has been detected in Open Asset Import Library Assimp 17c12da. The impacted element is the function Assimp::MDLImporter::GenerateOutputMeshes_3DGS_MDL7 of the file code/AssetLib/MDL/MDLLoader.cpp of the component 3DGS MDL7 Model Output Mesh Generator. The manipulation leads to buffer overflow. Remote exploitation of the attack is possible. The exploit has been disclosed publicly and may be used. The project was informed of the problem early through an issue report but has not responded yet.

A weakness has been identified in Open Asset Import Library Assimp 17c12da in the function Assimp::MDLImporter::ReadFaces_3DGS_MDL7 in the file code/AssetLib/LWO/LWOLoader.h of the 3DGS MDL7 Model Parser component. Manipulation can lead to a heap-based buffer overflow. The attack can be launched remotely, and the exploit is publicly available.

A security flaw has been discovered in Open Asset Import Library Assimp 17c12da in the function Assimp::Compression::decompressBlock of the file code/Common/Compression.cpp of the File Parser component. Manipulation results in a heap-based buffer overflow. The attack can be initiated remotely, and the exploit has been released publicly.

A vulnerability has been found in Open Asset Import Library Assimp up to version 6.0.5 in the function Assimp::CSMImporter::InternReadFile within CSMLoader.cpp. The flaw causes a heap-based buffer overflow when processing CSM files. The attack requires local access and an exploit has been published.

A vulnerability was found in Open Asset Import Library Assimp up to version 6.0.4 in the function Assimp::Exporter::ExportToBlob in file code/AssetLib/Ply/PlyLoader.cpp. Manipulation in PLY model handling leads to a double free. The attack can be initiated remotely, and the exploit has been publicly disclosed.

A heap-based buffer overflow vulnerability was found in Open Asset Import Library Assimp up to version 5.4.3 in the Assimp::SceneCombiner::Copy function. Manipulating width/height arguments triggers the overflow.

In Assimp up to 6.0.4, the HL1MDLLoader::read_sequence_infos function has an out-of-bounds read via the aiString argument. Local access required; exploit public.
