jsowl
JsOwl 是一个使用 Go 编写的高性能 JavaScript 信息收集与安全分析工具，同时也是一个可复用的 Go 库。它自动收集目标站点的页面、JavaScript、Webpack/RequireJS chunk 与 SPA 运行时资源，通过正则与 AST（Tree-sitter）提取 API 端点、参数、路由和敏感信息（密钥、Token、身份证、内网 IP 等），并生成 JSON 与自包含的交互式 HTML 报告——是 Web 安全测试、渗透测试信息收集阶段和攻击面梳理的自动化利器。

Grade D
Two or more Medium findings, or a High. Only try it in a sandbox.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
PERMISSION_SHELL_UNDECLARED NETWORK_HOST_FROM_INPUT
Why this grade
- PERMISSION_SHELL_UNDECLARED Medium
Runs shell commands that the manifest or description does not mention.
e2e_test.go, line 63
build := exec.Command("go", "build", "-o", binary, "./cmd/jsowl") - NETWORK_HOST_FROM_INPUT Medium
A file takes a URL or endpoint as input and has no fixed host list.

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.
If you think this grade is wrong, email [email protected] with the entry link and your evidence. We aim to acknowledge within two working days and decide within seven. If we confirm an error, we aim to correct it within 24 hours of confirming it. These are aims, not guarantees.
Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
