HIGHPre-NVD 7.17.1—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 92% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
