OneLogin Bug Let Attackers Use API Keys to Steal OIDC Secrets and Impersonate Apps




Seriously? OneLogin *Again*?

OneLogin: Still Managing To Screw Things Up, Apparently

Oh, for the love of all that is holy. OneLogin, those geniuses over there, managed to let attackers waltz in and use API keys to pilfer OIDC secrets. Yes, you read that right. API keys. Like, the things you’re supposed to protect with your life? They were letting people just…use them.

Apparently, a flaw in their system allowed attackers to bypass security checks and snag tokens for applications using OneLogin’s Identity Provider (IdP). This means they could impersonate apps, access data, and generally cause chaos. The worst part? It wasn’t some zero-day exploit; it was a simple misconfiguration on their end. A misconfiguration! I swear, sometimes I think these companies are actively trying to get hacked.

They patched it, naturally, after people started noticing things were…off. But the damage is done. If you use OneLogin, go check your logs *now*. Assume you’ve been compromised and rotate those API keys faster than a politician changes their stance on an issue. And for God’s sake, enable multifactor authentication if you haven’t already – though honestly, at this point, it probably won’t matter.

The root cause? A failure to properly validate the scopes of API calls. Seriously, basic security 101 people! It allowed attackers to request more data than they should have been able to access. I’m starting to think “OneLogin” is a sarcastic name at this point.

Speaking of misconfigurations, I once had a sysadmin who thought putting the server room in the basement with no climate control was “good enough.” The UPS died during a heatwave. Let’s just say there were a lot of angry users and a very red-faced admin. Some people shouldn’t be allowed near computers, and some companies clearly shouldn’t be allowed to handle user data. OneLogin falls firmly into the latter category.
