  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by 0xShe on GitHub. Read the source before you install it.

Installation

Install the Php Open Redirect Audit AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/0xShe/PHP-Code-Audit-Skill/tree/main/php-open-redirect-audit
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/0xShe/PHP-Code-Audit-Skill.git /tmp/PHP-Code-Audit-Skill
mkdir -p .claude/skills
cp -r /tmp/PHP-Code-Audit-Skill/php-open-redirect-audit .claude/skills/php-open-redirect-audit
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Php Open Redirect Audit in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Php Open Redirect Audit on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Php Open Redirect Audit is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

PHP 开放重定向审计(php-open-redirect-audit)

分析 PHP 项目源码中,所有“跳转/重定向”行为是否可能被用户控制目的地址,导致钓鱼或 OAuth 等流程被劫持。

分级与编号

  • 详见:shared/SEVERITY_RATING.md
  • 漏洞编号:{C/H/M/L}-REDIR-{序号}

必检 Sink(强制)

识别以下跳转输出点:

  • header("Location: {value}")
  • <meta http-equiv="refresh" content="{value}">
  • redirect() / to() / return redirect({value})
  • 自定义跳转函数(内部最终调用 Location 输出)

可控性追踪(必做)

必须追踪以下两类变量:

  1. 目的地来源:通常来自 $_GET['next']/$_POST['url']/Referer/return_to
  2. 目的地校验:是否只允许相对路径、是否 allowlist、是否拒绝 scheme(http://///)、是否校验域名

绕过条件(必做)

必须识别并输出潜在绕过:

  • scheme 绕过://evil.com、http:%2f%2fevil.com
  • 编码绕过:双重编码、URL 编码的冒号/斜杠
  • 尾部/空白字符绕过(旧实现常见)

报告输出

{output_path}/vuln_audit/redir_{timestamp}.md

条目模板(强制)

每条漏洞必须包含:

  • 位置证据:跳转函数位置 + 路由
  • 数据流链:用户输入 -> 校验 -> header/redirect
  • 可利用前置条件:通常需登录(若在登录后跳转)与攻击者能否控制参数
  • 验证 PoC(必须真实路由;把目的地参数替换为真实字段名)
  • 修复建议:只允许相对路径 + 服务器端 allowlist + 对编码/scheme 做归一化后校验

证据引用(强制:来自 php-route-tracer)

每条开放重定向疑似漏洞必须逐项引用 trace 输出中 ## 9) Sink Evidence Type Checklist 的 REDIR 行对应证据要点(允许状态为待验证,但证据引用必须存在):

  1. EVID_REDIR_OUTPUT_POINT:跳转输出点位置证据(header/redirect 的最终输出位置)
  2. EVID_REDIR_DEST_SOURCE_MAPPING:目的地来源变量映射证据(从路由参数到目的地变量)
  3. EVID_REDIR_DEST_VALIDATION_NORMALIZATION:目的地校验/归一化/allowlist/refuse scheme 的分支证据(含编码绕过处理分支)

tracer 证据缺失处理(强制)

  • 若无法定位上述 1~3 任一关键证据要点:该漏洞状态只能标记为 ⚠️待验证,不得直接给出 ✅已确认可利用。

Frequently asked questions

What does the Php Open Redirect Audit AI skill do?

Why use Php Open Redirect Audit on TypingMind?

Because you install it once and use it with any model. Php Open Redirect Audit is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Php Open Redirect Audit in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/0xShe/PHP-Code-Audit-Skill/tree/main/php-open-redirect-audit. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Php Open Redirect Audit?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Php Open Redirect Audit?

As many as you like. As long as a model supports skills, you can use Php Open Redirect Audit with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Php Open Redirect Audit AI skill free?

It is published on GitHub by 0xShe. Check the repository for licensing terms. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
