Across Protocol has issued an urgent warning to its users, advising them to refrain from accessing its application or connecting their wallets. The cross-chain bridging platform, which facilitates asset transfers between Ethereum and other networks, is currently investigating a potential security breach.

The protocol issued the advisory via X on Tuesday, instructing users to avoid signing any transactions or approvals. While the exact nature of the incident remains unconfirmed, several users have reported unauthorized fund withdrawals. One user claimed a loss of $9,000 in USDC, while another reported losing 7,053 USDT across seven transactions on the Plasma blockchain.

In a separate security event, NEAR AI reported that attackers exploited a vulnerability in its AI infrastructure. The breach, which involved a remote code execution flaw in the SGLang engine, exposed account details for approximately 100 users and data from 18 AI agents. Compromised information included names, email addresses, and chat histories, with two customers having their API keys exposed.
