ECHO DEPENDENCY SECURITY BLITZ CLOSES SOCKET.IO VULNERABILITY
By RepoJournal · Filed · About Laravel
Laravel Echo shipped five critical dependency updates overnight, including a socket.io-parser patch that closes CVE-2026-33151 and hardens axios against prototype pollution attacks.
The socket.io-parser bump to 4.2.6 [1] fixes a known vulnerability that could affect real-time communication in production apps. That's the one that demands immediate attention. Running alongside it, axios upgraded to 1.15.2 [2] with prototype-pollution hardening for the Node HTTP adapter plus a Unix domain socket SSRF mitigation that closes a supply-chain attack vector. Flatted jumped to 3.4.2 [3] fixing CWE-1321, while minimatch's aggressive leap from 3.0.8 to 9.0.9 [4] brings major pattern-matching improvements. PostCSS landed at 8.5.14 [5] resolving custom syntax regressions. On the Moat side, the team shipped light theme support [6], improved naming conventions [7], and patched exit code handling [8], but these are polish work while Echo's security chain is tightening. This is a maintenance release that actually matters: your WebSocket layer is more secure, your HTTP client is hardened, and your CLI tools are more reliable.
