we actually used that page to build what we have now... has this been changed? or did we just mess things up at some point? |

where do I find docs to do this properly ... or in other words, where do I find docs to read how this should be fixed? |

```$redirect = $this->request->getQuery('redirect', [ 'controller' => 'Pages', 'action' => 'display', 'home' ]);``` I think this must be old and has not been updated at some point... |

What does your redirect code look like? |

might we have done something wrong on our end to allow redirect to go to an external page after loggin in? I just tried it again... came to https://www.our-site.com/users/login?redirect=%2F and I changed the redirect to https://www.some-evil-site.com/ and got redirected to the external site after logging in... |

@ndm really? because I manually changed redirect for the Authentication middleware plugin in the login page and after logging in, i was redirected to the google search engine landing page... Also, I am looking to do this in a place somewhere other then login ... it was just an example ... not meant to say there is a bug or security hole in there... I just was trying to figure out if and how that middleware handles external |

@alexdd55976 Use the authentication component, `getLoginRedirect()` will only return relative URLs, if someone crams in an absolute URL (internal or external), you'd receive `null`. |

Jun 21st 2021, 13:07 |
a.vanniel |
for now I did what you suggested regarding the host by the way... checking if the host in the redirect url (full) matches the current host... if not, it most likely isn't internal |
| # |
Jun 21st 2021, 13:06 |
a.vanniel |
It would be great to have an isInternal method inside Router... I don't think many people actually need this though.. I will open an issue on github. see where it goes. good luck on your 2nd shot... I need to wait until 12th of juli for the 2nd one. |

I would suggest you create an issue in the cakephp/cakephp repo. I dont know it/cant check right since im on my way to get my 2. vacine shot :) Or someone else can answer that ^^ |

What I don't really get, but there might some logic to this, is why the Google website counts as an existing route....? |

would normalize be able to help me out here? |

would like to prevent manipulation of the redirect param so that someone is not redirected anywhere externally after payment is done and after a user is coming back... the url is stored in the database for several reasons, one of which is because the payment provider is a pain in the behind about return urls. |
| # |
Jun 21st 2021, 12:16 |
a.vanniel |
it's not that I would want this to be added to the middleware per se... it was more of a thing that I am using similar logic (redirect param) and after doing the thing, redirect the user to the redirect param and when I looked at the Authentication middleware I did not see any security in place to prevent someone/something from redirecting someone to something externally after a login... I am doing this after a payment and I |

Jun 21st 2021, 12:11 |
kevin.pfeifer |
we could make that a configurable option |
| # |
Jun 21st 2021, 12:11 |
kevin.pfeifer |
then that would have to be added to this function i guess https://github.com/cakephp/authentication/blob/de989c759937406f514a5a31313b36578005b07c/src/AuthenticationService.php#L360 |

maybe I am just making things more complex than need be but it feels like a securiy hole in the location I have this ?redirect= param... |
| # |
Jun 21st 2021, 12:08 |
a.vanniel |
but that is when a user is about to or just has been redirected, right? |
| # |
Jun 21st 2021, 12:07 |
kevin.pfeifer |
you could use https://github.com/cakephp/cakephp/blob/master/src/Routing/Router.php#L225 and catch the MissingRouteException |
| # |
Jun 21st 2021, 12:07 |
a.vanniel |
alright... thing is that with the Authentication middleware, relative redirects are used, to make sure the param does not get too large I guess... |
| # |
Jun 21st 2021, 12:06 |
a.vanniel |
I thought I'd take a look at Router::routeExists() but that actually returns true for external URLs. ... |
| # |
Jun 21st 2021, 12:06 |
kevin.pfeifer |
to be fair, all the redirect param logic I know always uses absolute urls |
| # |
Jun 21st 2021, 12:04 |
kevin.pfeifer |
well if you force your redirect param to be absoulte all the time then you can check that pretty easily with a parse_url |
| # |
Jun 21st 2021, 11:59 |
a.vanniel |
I though I would check how the Authentication middleware handles this... but when you open a login screen, change the ?redirect= to something else and log in, you are then redirected to the external page I entered in ?redirect=... I had expected this would really force redirect to be local/matching route but it doesn't |
| # |
Jun 21st 2021, 11:57 |
a.vanniel |
the latter might not work when a relative path unless the Router first qualifies the use given url ofcourse |

matches a route" and the "check for host" method... |
| # |
Jun 21st 2021, 11:57 |
a.vanniel |
Basically I want to prevent someone (or something) from entering https://www.google.com in the ?redirect= , so that when they would hit refresh and after the form has been posted they would not be transported to https://www.google.com ... and where this google url is set, any other malicious url could be set and you could replace the user by any malicious script I guess. So I am conflicted between the "check if the url |
| # |
Jun 21st 2021, 11:53 |
kevin.pfeifer |
so you want to know if a given URL matches any route in your app? Or are you happy if you check the host part of the url? |
| # |
Jun 21st 2021, 11:47 |
slackebot1 |
or /pages/display/home to be returned. Is this as all possible? |
| # |
Jun 21st 2021, 11:47 |
a.vanniel |
Does anybody know if there is a way to filter a user supplied url? Basically what I would like to do is populate a query variable and I want to sanitize this variable so it does not contain an external url... I thought passing something to Router::url() would solve my problems but when I pass somethign like https://www.google.com to Router::url() I am just getting the same url back, instead I would have liked something like / |

@alamnaryab what are you trying to accomplish with that logic? As far as I know the `$connection->rollback();` only works for manually executed queries like ```$connection->execute('UPDATE articles SET published = ? WHERE id = ?', [true, 2]);``` If you go through the ORM with `$connection->Tags->save($tag)` you can’t rollback from that. But again, what are you trying to accomplish? |
