xslt-injection skillB

xslt-injection is agent-read markdown (skill) from dreadnode/capabilities: Exploit XSLT processor injection for file read, SSRF, and RCE. Use when target processes XML with user-influenced stylesheets — file upload, PDF generation, XML transformation endpoints..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add dreadnode/capabilities/xslt-injection@git:20260518.7b5f854
Exact content
mdr add dreadnode/capabilities/xslt-injection@sha256:6734fc5470d57b70

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
