Detailsinfo

A vulnerability classified as problematic has been found in Assimp up to 6.0.6. Affected is an unknown code of the component glTF/glTF2 Importers. The manipulation of the argument uri with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22.
