MEDIUM4.7EPSS 0.00%ONNX: Arbitrary File Read via ExternalData Hardlink Bypass in ONNX load
發布日:2026/4/1修改日:2026/4/28
描述
Open Neural Network Exchange (ONNX) is an open standard for machine learning interoperability. Prior to version 1.21.0, there is an issue in onnx.load, the code checks for symlinks to prevent path traversal, but completely misses hardlinks because a hardlink looks exactly like a regular file on the filesystem. This issue has been patched in version 1.21.0.
