Method Detail

makeSafeRedirectUrl

@Nullable
String makeSafeRedirectUrl(@Nullable
                                     String redirectUrl)

Constructs a safe redirect URL out of user-provided input. This means checking that the URL has an HTTP or HTTPS scheme, and that it does not redirect to a different domain (i.e. not JIRA). If the redirectUrl does not meet these conditions, this method returns null.

This is used to prevent Open redirect attacks, which facilitate phishing attacks against JIRA users.

Parameters:

redirectUrl - a String containing the redirect URL

Returns:

a safe redirect URL, or null

Since:

5.1.5

canRedirectTo

boolean canRedirectTo(@Nullable
                      String redirectUri)

Returns a boolean indicating whether redirecting to the given URI is allowed or not.

This method returns false if the redirectUri is an absolute URI and it points to a domain that is not this JIRA instance's domain, and true otherwise. If the uri is in the form //xxx then it is not allowed as per JRA-27405. If the uri contains any non-valid URL character, like backslashes, it is denied redirection as it could result in a potential open redirect attack.

Parameters:

redirectUri - a String containing a URI

Returns:

a boolean indicating whether redirecting to the given URI should be allowed or not
