cspt-xss skillB

cspt-xss is agent-read markdown (skill) from dreadnode/capabilities: Client-Side Path Traversal — exploit CSR/SSR apps where URL parameters control fetch/XHR paths to inject cross-origin responses, achieve XSS, CSRF, or SSRF. Covers all 8 major frameworks with source-code-level decoding pipeline analysis, query param universality, secondary context (server-side) traversal, and per-framework XSS sinks. Use when any SPA/hybrid app fetches API data using URL-derived path segments..

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/cspt-xss@git:20260504.2a64374
Exact content
mdr add dreadnode/capabilities/cspt-xss@sha256:089152a698364789

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.
