Detailsinfo

A vulnerability classified as critical was found in tinygltf up to 2.5.x. This vulnerability affects the function wordexp of the component Backtick Handler. The manipulation with an unknown input leads to a os command injection vulnerability. The CWE definition for the vulnerability is CWE-78.

The tinygltf library uses the C library function wordexp() to perform file path expansion on untrusted paths that are provided from the input file. This function allows for command injection by using backticks. An attacker could craft an untrusted path input that would result in a path expansion. We recommend upgrading to 2.6.0 or past commit 52ff00a38447f06a17eab1caa2cf0730a119c751
