JWTXploiter is a tool to test security of JSON Web Tokens. Test a JWT against all known CVEs;

  • Tamper with the token payload: changes claims and subclaims values.
  • Exploit known vulnerable header claims (kid, jku, x5u)
  • Verify a token
  • Retrieve the public key of your target’s ssl connection and try to use it in a key confusion attack with one option only
  • All JWAs supported
  • Generates a JWK and insert it in the token header
  • And much, much more!
