WalletConnect, a widely used protocol, acts as a bridge between decentralized applications (dApps) and cryptocurrency wallets, enabling seamless interactions. The vulnerability was traced back to a cross-site scripting (XSS) flaw that could be exploited through the creation of a phishing site. This fraudulent site aimed to deceive users into unknowingly authorizing malicious transactions, capitalizing on the inherent trust users place in WalletConnect's domain name.
