CVE-2026-50181: Langroid: Files can be accessed outside the intended directory
CVE-2026-50181 · published 3 months ago
Summary
Langroid's file tools can be tricked into reading or writing files outside the project directory. This is a concern if Langroid is used by untrusted users or agents, as it could allow them to access sensitive files. To fix this, Langroid's developers should ensure that file paths are properly validated and restricted to the intended directory.
What to do
- Update prasad chalasani langroid to version 0.64.0.

Original advisory text
Langroid: Path traversal in the file tools allows read/write outside configured current directory
Langroid is a framework for building large-language-model-powered applications. Prior to version 0.64.0, Langroid's `ReadFileTool` and `WriteFileTool` appear to treat `curr_dir` as the intended working-directory boundary for file operations. However, the tools only change the process working directory to `curr_dir` and then operate on the user-supplied `file_path` without resolving and enforcing that the final path remains inside `curr_dir`. As a result, a tool caller can supply path traversal sequences such as `../secret.txt` to read files outside the configured current directory, or `../written_by_tool.txt` to write files outside that directory. This can impact applications that expose Langroid file tools to an LLM agent, user-controlled tool call, or delegated coding/documentation agent while relying on `curr_dir` to restrict file access to a project/workspace directory. Version 0.64.0 patches the issue.
