CVE-2025-51482 is a remote code execution vulnerability in letta-ai Letta 0.7.12. According to the provided content, the flaw is in letta.server.rest_api.routers.v1.tools.run_tool_from_source and can be triggered via crafted payloads sent to the /v1/tools/run endpoint. The issue allows remote attackers to execute arbitrary Python code and system commands, indicating that untrusted input is being processed in a way that bypasses the endpoint's intended sandbox restrictions.

This repository contains a working exploit for CVE-2025-51482, targeting a remote code execution (RCE) vulnerability in a Letta product. The exploit is implemented in a single Python script (RCE.py) that sends a crafted POST request to the /v1/tools/run endpoint of a vulnerable server. The payload leverages the lack of input validation and unsafe code execution on the server, injecting Python code that executes arbitrary system commands via os.popen. The script allows the attacker to specify the target URL and the command to execute, and prints the output of the command if successful. The README.md provides a detailed vulnerability analysis, including the root causes (lack of code safety checks, unsafe exec usage, environment variable exposure, and sandbox bypasses) and usage examples. The exploit is operational and can be used to gain remote shell access or execute arbitrary commands on affected systems. The only fingerprintable endpoint is the /v1/tools/run API path, which is the target of the exploit.
