⚠️ Critical Anthropic’s MCP Vulnerability Enables Remote Code Execution Attacks Source: cybersecuritynews.com/anthro… A critical flaw in Anthropic’s Model Context Protocol (MCP) exposes over 150 million downloads to potential compromise. The vulnerability could enable full system takeover across up to 200,000 servers. Unlike a traditional coding bug, this vulnerability is architectural, meaning any developer building on Anthropic's MCP foundation unknowingly inherits the exposure from the ground up. The flaw enables Arbitrary Command Execution (RCE) on any system running a vulnerable MCP implementation. Successful exploitation grants attackers direct access to sensitive user data, internal databases, API keys, and chat histories, effectively handing over complete control of the affected environment. #cybersecuritynews

@The_Cyber_News Opera Browser 0-Day Flaw Allows Extensions to Takeover Browser Source: cybersecuritynews.com/opera-… A critical vulnerability in the Opera web browser has been discovered that could allow malicious extensions to gain unauthorized access to private APIs, potentially leading to account hijacking and other severe security breaches. The vulnerability stemmed from Opera’s use of special web apps under specific domains with unique privileges to support features like Opera Flow, Opera Wallet, and Pinboard. These domains were granted access to private APIs embedded in Opera’s native code. Researchers found malicious extensions could exploit this setup to inject code into these privileged domains, bypassing intended security measures. #cybersecurity #vulnerability
