Warpcast Fix: Wallet Verifications @horsefacts.eth patched a Warpcast issue last night that allowed someone to connect their wallet to your fid under some conditions. To the best of our knowledge, no one took advantage of the issue on Warpcast before we fixed it. Thanks to @0xsec.eth for reporting this!

If you want to verify a wallet on Warpcast.com, it creates a url where you can submit a signature from your wallet. Warpcast counter signs this with the signer it has for your account. The problem is that the submission url is predictable and wasn't closed when the verification was submitted. So someone watching the hubs for your verification could “back run” and post their own wallet verification to that URL, and Warpcast would have counter signed it with your signer, adding both wallets.

Could it be why I'm having an issue with warpcast login? It's telling me to open the link in mobile and I am doing just that but nothing happens. Android.

Gn Varun I also found a bug in Warpcast. Sometimes the B&W images appears in negative, like on this screenshot. And if I download it, I can see it perfectly. Have you noticed this before?
