CVE-2026-34730

Summary: CVE-2026-34730 affects Copier prior to version 9.14.1, where the optional _external_data feature allows template-controlled paths to load YAML files. This can enable destination-external reads, including parent-directory traversal (e.g., ../secret.yml) and absolute paths, exposing the co...

Copier 路径遍历漏洞

Copier is an open-source library developed by Copier for rendering project templates. Versions of Copier prior to 9.14.1 contained a path traversal vulnerability. This vulnerability stemmed from the externaldata function, which allowed templates to load YAML files using path-based operations...

GHSA-Q56X-G2FJ-4RJ6 ONNX: TOCTOU arbitrary file read/write in save_external_dat

Summary The saveexternaldata method seems to include multiple issues introducing a local TOCTOU vulnerability, an arbitrary file read/write on any system. It potentially includes a path validation bypass on Windows systems. Regarding the TOCTOU, an attacker seems to be able to overwrite victim's...

Time-of-check Time-of-use (TOCTOU) Race Condition

Overview onnx is an Open Neural Network Exchange Affected versions of this package are vulnerable to Time-of-check Time-of-use TOCTOU Race Condition through the saveexternaldata function. An attacker can overwrite arbitrary files or inject data into sensitive locations by exploiting a race...

GHSA-HGJQ-P8CR-GG4H Copier `_external_data` allows path traversal and absolute-path local file read without unsafe mode

Summary Copier's externaldata feature allows a template to load YAML files using template-controlled paths. The documentation describes these values as relative paths from the subproject destination, so relative paths themselves appear to be part of the intended feature model. However, the curren...

GHSA-538C-55JV-C5G9 ONNX: Malicious ONNX models can crash servers by exploiting unprotected object settings.

Summary The ExternalDataInfo class in ONNX was using Python’s setattr function to load metadata like file paths or data lengths directly from an ONNX model file. The problem? It didn’t check if the "keys" in the file were valid. Because it blindly trusted the file, an attacker could craft a...
