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...

Directory Traversal

Overview copier is an A library for rendering project templates. Affected versions of this package are vulnerable to Directory Traversal via the externaldata paths. If a user runs Copier on an untrusted template, an attacker can access and expose the contents of arbitrary local files by supplying...

External Control of File Name or Path

Overview sillytavern is a LLM Frontend for Power Users Affected versions of this package are vulnerable to External Control of File Name or Path via the /api/chats/import endpoint when unsanitized input in the charactername parameter is used to construct file paths. An attacker can write arbitrar...

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...

Open WebUI has Broken Access Control in Tool Valves

Summary Broken Access Control in Tool Valves Open WebUI supports function calling through "Tools". Function calling allows an LLM to reliably connect to external tools and interact with external APIs. Exemplary use-cases include connecting to an internal knowledge base, retrieving emails from an...

CVE-2026-34445

A flaw was found in Open Neural Network Exchange ONNX. An attacker could exploit a vulnerability in how ONNX processes model metadata, specifically within the ExternalDataInfo class. By crafting a malicious ONNX model, an attacker could overwrite internal object properties, leading to a denial of...
