The redirect_uri is checked against the app registration. There's a general OAuth problem called "open registration redirects" that applies here, about which we've [blogged](https://www.microsoft.com/en-us/security/blog/2026/03/02/oau...) - but frankly, none of the industry solves this well.
In general, "I can create a link that goes to malware via X endpoint" isn't very interesting - you can also just create a direct link to the malware. Web browsers won't reliably show you the real destination of a link anyhow and even if they did, it's mostly just us hackers who understand URLs at all.

I'm lost. Entra supports [OpenID Connect](https://learn.microsoft.com/en-us/entra/identity-platform/v2...) for authentication. Most portals that surface admin consent authenticate the user with an OpenID Connect request either immediately before or after the admin consent request.
Once I could reach the actual engineering team to look at the internal tool to look at the bug I had to report though, they were very responsive. The tool for communicating was cumbersome and made me feel like a vendor / customer relationship even though you are supposed to be the same team but once they realized it was an actual defect and not some harebrained feature request, they fixed it relatively quickly.
