self-xss-escalation skillA

self-xss-escalation is agent-read markdown (skill) from dreadnode/capabilities: Escalate self-XSS to full-impact XSS via login CSRF, cookie bombing, path-specific cookie precedence, and double-XSS chains. Use when you have XSS that only fires in the attacker's own session..

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/self-xss-escalation@git:20260529.17de87f
Exact content
mdr add dreadnode/capabilities/self-xss-escalation@sha256:8cbca624d0b64b94

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.
