Security vulnerabilities in leanrea's benchmark runner, specifically broad Bash permissions and unsafe cleanup.

Technical Positioning
Secure execution environment, robust sandboxing, and prevention of command injection vulnerabilities.
SaaS Insight & Market Implications
This issue identifies critical security vulnerabilities within leanrea's benchmark runner, specifically concerning broad Bash tool preapproval and an unquoted cleanup command. The lack of enforced OS sandboxing, combined with preapproved Bash access, creates a high-severity risk for command injection if attacker-controlled inputs are processed. This directly exposes host files, credentials, and network access. For B2B SaaS, security flaws of this magnitude are unacceptable, particularly in tools designed for code analysis or reverse engineering where untrusted inputs are common. Market implication: products with demonstrable security vulnerabilities, especially those enabling arbitrary code execution, will face immediate rejection in enterprise environments. Robust sandboxing and stringent input validation are non-negotiable for B2B adoption in security-sensitive domains.

Security: broad benchmark Bash permissions and unsafe unquoted cleanup

Security review of commit `09ba4aa0217f82cd880f855a60b877f59f39b22b` identified two issues: broad tool preapproval in the benchmark runner, and an unquoted cleanup command that can delete unintended directories.

## 1. Broad Bash preapproval without enforced isolation in the benchmark

**Suggested severity: High, conditional on the execution environment and processing attacker-controlled artifacts.**

Source: [bench/run.py, lines 15–28](github.com/aicodeking/leanre...

The runner launches Claude with:

```text
--allowedTools Bash,Read,Grep,Glob,Write,Skill,mcp__rea
```

It does not itself enforce an OS sandbox or supply a filtered subprocess environment. Setting the working directory to a fresh copy of the targets does not isolate shell commands from the rest of the host.

According to the [Claude Code CLI reference](code.claude.com/docs/en/cli-refer... `--allowedTools` preapproves tools without prompting; it does not restrict the available tools. External deny rules, managed policies and any existing sandbox configuration can still apply.

**Potential impact:** if attacker-controlled strings, source or other content encountered during analysis successfully inject instructions into the agent, broad Bash preapproval could allow commands that access host files, inherited credentials or the network, subject to external restrictions. This is a risk scenario, not a demonstrated prompt-injection e...
