  "details": "### Impact\nA url `/login?came_from=////evil.example` may redirect to an external website after login.\n\nStandard Plone is not affected, but if you have customised the login, for example with add-ons, you might be affected. You can try the url to check if you are affected or not.\n\n### Patches\nThe problem has been patched in `Products.isurlinportal`.\n\n* Plone 6.2: upgrade to `Products.isurlinportal` 4.0.0.\n* Plone 6.1: upgrade to `Products.isurlinportal` 3.1.0.\n* Plone 6.0: upgrade to `Products.isurlinportal` 2.1.0.\n* Older Plone versions don\u0027t have security support anymore.\n\n### Workarounds\nThere are no known workarounds.\n\n### Background\nWhen you are anonymous and land on a page that requires a login, Plone sends you to the login form. After successful login, Plone redirects you back to the page you came from.  Various other forms and pages have a similar system.\n\nThis could get abused by an attacker to trick Plone into redirecting to a different website. Plone checks the page that would be redirected to. It is only accepted if it is within the Plone site domain or part of a different trusted domain.\n\nThe main check for this is in the `Products.isurlinportal` package. A lot of potentially malicious urls are already safely rejected, but here a loop hole was found.\n\nThis was discovered during a penetration test by the CERT-EU Team.",
