Ticket #36206 – Description
initial v2 1 1. Incorrect use of response.setdefault() instead of response.headers.setdefault() 1 1. Incorrect use of `response.setdefault()` instead of `response.headers.setdefault()` 2 2 3 Issue: 3 4 In the original code, the Cross-Origin-Opener-Policy (COOP) header is set using: 4 5 {{{#!python 5 6 response.setdefault("Cross-Origin-Opener-Policy", self.cross_origin_opener_policy) 6 7 }}} 7 8 This is incorrect because: 8 9 9 a. response.setdefault() does not exist in Django’s HttpResponseclass.10 b. Headers should be set using response.headers.setdefault()to ensure they are only added if they don’t already exist.10 a. `response.setdefault()` does not exist in Django’s `HttpResponse` class. 11 b. Headers should be set using `response.headers.setdefault()` to ensure they are only added if they don’t already exist. 11 12 12 13 Suggested Modification: 13 14 Replace: 14 15 {{{#!python 15 16 response.setdefault("Cross-Origin-Opener-Policy", self.cross_origin_opener_policy) 16 17 }}} 17 18 With: 18 19 {{{#!python 19 20 response.headers.setdefault("Cross-Origin-Opener-Policy", self.cross_origin_opener_policy) 21 }}} 20 22 21 23 2. Improving String Formatting for Readability & Performance … … 23 25 Issue: 24 26 In the process_request() method, HTTPS redirection is done using: 25 27 {{{#!python 26 28 return HttpResponsePermanentRedirect( 27 29 "https://%s%s" % (host, request.get_full_path()) 28 30 ) 29 31 }}} 30 32 While this works, %-formatting is less readable and slightly less performant than modern alternatives like f-strings. 31 33 32 34 Suggested Modification: 33 35 Change: 34 36 {{{#!python 35 37 return HttpResponsePermanentRedirect( 36 38 "https://%s%s" % (host, request.get_full_path()) 37 39 ) 38 40 }}} 39 41 To: 42 {{{#!python 40 43 return HttpResponsePermanentRedirect(f"https://{host}{request.get_full_path()}") 41 44 }}} 42 45 43 46 3. Preventing Overwriting of Existing Headers … … 46 49 47 50 The original code unconditionally sets security headers like: 48 51 {{{#!python 49 52 response.headers["Strict-Transport-Security"] = sts_header 50 53 response.headers["X-Content-Type-Options"] = "nosniff" 51 52 53 This could Override existing security policies set by other middleware or custom responses & 54 }}} 55 is could Override existing security policies set by other middleware or custom responses & 54 56 Prevent flexibility in modifying security headers dynamically. 55 57 56 58 Suggested Modification: 57 59 58 Use setdefault()instead of direct assignment:59 60 Use `setdefault()` instead of direct assignment: 61 {{{#!python 60 62 response.headers.setdefault("Strict-Transport-Security", sts_header) 61 63 response.headers.setdefault("X-Content-Type-Options", "nosniff") 62 64 }}} 63 65 64 66 Suggested Code: 65 67 {{{#!python 66 68 import re 67 69 … … 128 130 129 131 return response 132 }}}
