Security Findings1

Severity	Finding	Layer	Location
CRITICAL	Command Injection via Unquoted User Input in `curl` URL The `WD`, `pageNum`, and `enable_abstract` variables, which are derived directly from untrusted user input (`$1`, `$2`, `$3`), are interpolated into the `curl` command's URL string without proper shell quoting or URL encoding. This allows an attacker to inject shell metacharacters (e.g., `;`, `\|`, `$(...)`) into the arguments, leading to arbitrary command execution on the host system. For example, providing `WD="; rm -rf /; echo "` could execute `rm -rf /`. To prevent command injection, use `curl`'s `-G` (for GET requests) and `--data-urlencode` options for each parameter. This ensures that `curl` handles the URL encoding of the parameter values safely and prevents shell interpretation of user input. Modified snippet: ```bash curl -s -X GET \ -H "Authorization: Bearer $BAIDU_API_KEY" \ -H "X-Appbuilder-From: openclaw" \ -G \ --data-urlencode "wd=$WD" \ --data-urlencode "pageNum=$pageNum" \ --data-urlencode "enable_abstract=$enable_abstract" \ "https://qianfan.baidubce.com/v2/tools/baidu_scholar/search" ```	LLM	baidu_scholar_search.sh:30
