CVE-2026-2265 — AI Deep Analysis Summary

**Nature**: Replicator 1.0.5 contains a **deserialization vulnerability** 🚨 **Impact**: Can lead to **Remote Code Execution (RCE)** 💥

**CWE-502**: Insecure Deserialization • The component trusts **unverified data** 🔓 • Attackers inject malicious serialized objects → execute arbitrary code

**Replicator ≤ 1.0.5** 📦 • npm package `replicator` • Used for Node.js object serialization/deserialization

**Full server control** 🎮 • Execute arbitrary system commands • Steal sensitive data 🔑 • Deploy backdoors / lateral movement

**Low barrier to exploit** ⚠️ • No authentication required • Only requires the target application to **deserialize untrusted input** • Network accessibility is sufficient for attack

**No public PoC available** ❓ • Reference links contain technical analysis details • Monitor https://morielharush.github.io/ for updates • ⚡ May be disclosed at any time

**Self-check checklist** 🔍 • Run `npm list replicator` to check version • Search code for `replicator.decode()` calls • Verify if input sources are **externally controllable**

**Fixed** ✅ • PR #19 merged: https://github.com/inikulin/replicator/pull/19 • Upgrade to **1.0.6+**

**Temporary mitigation** 🛡️ • Upgrade! Upgrade! Upgrade! • If unable to upgrade: filter/whitelist serialized input • Restrict access from untrusted sources at network layer

**🔥 Emergency response** • **CVSS estimated: High (8.0+)** • RCE + low barrier = extremely high weaponization risk • **Complete upgrade within 24 hours** ⏰
