  "details": "URL Redirection to Untrusted Site ('Open Redirect') vulnerability in phoenixframework phoenix_live_view allows an attacker to send a victim's browser to an origin of the attacker's choosing via a :to value containing ASCII tab, LF or CR.\n\nredirect/2 validates :to through the private validate_local_url!/2 in lib/phoenix_live_view.ex, which is intended to guarantee the target is a path within the application. It rejects a leading // and any backslash, but not ASCII tab, LF or CR. Browsers strip those three characters before parsing a URL, so a value such as /\u003cTAB\u003e/example.com passes validation as a path and is then resolved as the scheme-relative URL //example.com. The live navigation functions share the guard but are not affected, because the client expands their target against the current origin. push_patch/2 is also affected before 0.7.0, which is when that expansion was added.\n\nThis issue affects phoenix_live_view: from 0.5.0 before 1.0.19, from 1.1.0-rc.0 before 1.1.33, and from 1.2.0-rc.0 before 1.2.9.",
