Templates

from PyNuclei import Nuclei

nucleiScanner = Nuclei()

"""
All active templates.
"""
print(nucleiScanner.nucleiTemplates)
[
    "cnvd", "cves", "default-logins", "exposed-panels",
    "exposures", "file", "misconfiguration",
    "miscellaneous", "takeovers", "technologies",
    "token-spray", "vulnerabilities", "network",

]

"""
Returns details of all nuclei templates in JSON format
"""
print(nucleiScanner.returnTemplatesDetails())

NOTE: You can run ignored templates by passing them in the template parameter in nucleiScanner.scan(<host>, template=nucleiScanner.ignoredTemplates)
