CVE-2026-50181Public exploit

Workspace file escape via unchecked relative paths

Published Jul 9, 2026 · Updated Jul 9, 2026

Path traversal in Langroid before 0.64.0 allows attackers to read or write files outside the configured workspace via crafted paths. ReadFileTool and WriteFileTool change into curr_dir, then use the caller-controlled file_path without resolving it and verifying that the target remains below that directory. Exposure requires an application to enable these tools and let an LLM agent or other caller influence their path arguments; successful access is limited by the host process's filesystem permissions.
