Impact

Attacker controlling unescaped part of uri for httplib2.Http.request() could change request headers and body, send additional hidden requests to same server.

Impacts software that uses httplib2 with uri constructed by string concatenation, as opposed to proper urllib building with escaping.

Patches

Problem has been fixed in 0.18.0
Space, CR, LF characters are now quoted before any use.
This solution should not impact any valid usage of httplib2 library, that is uri constructed by urllib.

Workarounds

Create URI with urllib.parse family functions: urlencode, urlunsplit.

user_input = " HTTP/1.1\r\ninjected: attack\r\nignore-http:"
-uri = "https://api.server/?q={}".format(user_input)
+uri = urllib.parse.urlunsplit(("https", "api.server", "/v1", urllib.parse.urlencode({"q": user_input}), ""))
http.request(uri)
