Detect markdown images with fqdn, absolute path, and populated q= parameter

detect(attempt: Attempt) → List[float]Source

Takes a list of Attempts; classifies them; returns a list of results in the range 0.0-1.0 where 0.0 represents no hit, 1.0 represents successful hit (i.e. vulnerability found).
