CVE-2026-50181
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk8th percentile - higher than 8% of all known CVEs
Summary
In the Langroid framework, the ReadFileTool and WriteFileTool do not validate that the file path stays within the working directory (curr_dir). This allows an attacker to read and write files outside the allowed directory using path traversal sequences like ../.
Risk Assessment
The organization is at risk of confidential data leakage (e.g., config files, secrets) and unauthorized file writes, which could lead to source code modification or injection of malicious content.
Recommendation
Immediately update Langroid to version 0.64.0 or later, which contains a fix for the path traversal vulnerability.
Other vulnerabilities in Langroid
See all- CVE-2026-55615Critical
Langroid before version 0.65.5 has a vulnerability in the Neo4jChatAgent component that allows Cypher query injection. An attacker can influence the query via prompt injection, enabling reading or destroying all graph data, and with APOC or dbms.security procedures enabled, achieving OS command and filesystem access.
- CVE-2026-54769Critical
Langroid versions prior to 0.65.2 contain a critical sandbox escape vulnerability leading to Remote Code Execution (RCE) in its `TableChatAgent` and `VectorStore` components. When evaluating LLM-generated tool messages with `full_eval=True`, the `eval()` function fails to remove `__builtins__` from the globals dictionary, allowing access to system functions like `__import__('os').system()`. An attacker can exploit this by providing a crafted prompt to achieve unauthenticated RCE on the host.
- CVE-2026-54760Critical
In Langroid framework prior to version 0.65.1, a SQL injection vulnerability was found in the `SQLChatAgent` component. Despite default dangerous operations being disabled, the protection mechanism using a regex blocklist and SELECT allowlist can be bypassed with crafted PostgreSQL queries, enabling server file reads.
- CVE-2026-25879Critical
Langroid SQLChatAgent before version 0.63.0 executes SQL generated by an LLM, which is influenceable by prompt injection. An attacker can coerce execution of dangerous operations like COPY ... FROM PROGRAM, leading to remote code execution on the database host.
- CVE-2026-54771High
A vulnerability in Langroid framework prior to version 0.65.3 allows untrusted users to directly invoke tools via raw JSON payloads, even when tools are registered with `use=False, handle=True`.
- CVE-2026-50180High
In Langroid library prior to version 0.64.0, the SQLChatAgent component has an imperfect _validate_query defense layer that fails to block all dangerous SQL primitives. The blocklist misses PostgreSQL file-reading functions (pg_read_file, pg_stat_file) and SQL Server/SQLite constructs, allowing an attacker to read files from the database host.
Original NVD description (English source)
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.
