Critical React Vulnerability Sparks Crypto Security Crisis
A zero-day exploit in React Server Components (CVE-2025-55182) has unleashed a wave of crypto-drainer attacks, compromising front-end security across Web3 platforms. The flaw, rated CVSS 10.0, allows malicious actors to intercept wallet communications and redirect funds through poisoned permit signatures.
Security Alliance reports threat actors are actively weaponizing the vulnerability, targeting React-powered interfaces from decentralized apps to exchange portals. The breach stems from flawed payload decoding in React versions 19.0 through 19.1.0, enabling remote code execution via crafted HTTP requests.
Crypto projects face urgent front-end audits as attackers exploit the window between disclosure and patches. The incident underscores the fragility of JavaScript dependencies in financial infrastructure—where a single library flaw can cascade across BTC, ETH, and SOL ecosystems alike.
