xml-parser-security SKILL.md skillA
xml-parser-security from hellodqy/mastermind-bug-bounty is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add hellodqy/mastermind-bug-bounty/xml-parser-security@git:20260915.d2c52f2Pins git:20260915.d2c52f2 in mdr.lock. Pin the fingerprint instead.

Test XML, XInclude, XSLT, SVG, SOAP, SAML, and Office-document processing when parser features may cross file, network, transformation, or trust boundaries.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# XML Parser Security ## Goal 识别真实解析器、输入载体和外部资源策略，用分层证据判断 XML/XSLT 处理是否能读取文件、发起服务端请求或执行危险扩展。 ## Tools / Inputs - XML/SOAP/SAML 请求、SVG/Office 上传、转换/预览功能、错误差分、受控 OOB 端点 - 资源索引：`references/INDEX.md`；候选资源：`xml-parser-security.md`、`ssrf-testing.md` ## Constraints 1. 先确认解析器和载体，再选择 DOCTYPE、XInclude 或 XSLT 假设。 2. 优先使用自控 OOB、无敏感标识文件和常量转换结果。 3. OOB 命中只证明外部解析或请求，不自动证明文件读取或代码执行。 4. 不读取无关文件，不使用危险 XSLT 扩展执行生产命令。 5. 压缩文档样本限制大小、层级和条目数量。 ## Chain Questions - 输入由哪个组件以何种模式解析，DOCTYPE、实体、XInclude 和扩展函数是否启用？ - 校验、签名和业务消费是否作用于同一棵 XML 树？ - 外部访问能否升级为受控文件读取、SSRF 或转换器权限滥用？ - SVG、Office、SOAP、SAML 与直接 XML 是否共享同一解析链？

How to install
mdr add hellodqy/mastermind-bug-bounty/xml-parser-security@sha256:55d58a5e77d08786The line at the top of this page pins the label git:20260915.d2c52f2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
