CVE-2024-27307 — AI Deep Analysis Summary

🚨 **Essence**: JSONata (v1.4.0 - 2.0.4) has a critical flaw. Malicious expressions can overwrite object constructors & prototypes.…

🛡️ **Root Cause**: CWE-1321: Improper Variable/Prototype Manipulation. The transformation operator allows attackers to hijack core JavaScript objects.…

📦 **Affected**: `jsonata-js` / `jsonata` library. 📅 **Versions**: 1.4.0 up to (but not including) 2.0.4. ⚠️ **Scope**: Any app using these versions for JSON querying/transformation.

🔓 **Privileges**: Full Remote Code Execution (RCE). 📂 **Data**: Complete system compromise. 🚫 **DoS**: Can crash the application. 🌐 **Network**: Exploitable over the network (AV:N).

🔓 **Threshold**: LOW. 🚫 **Auth**: None required (PR:N). 👁️ **UI**: No user interaction needed (UI:N). 🎯 **Complexity**: Low (AC:L). Easy to exploit remotely.

🕵️ **Public Exploit**: No specific PoC code provided in data. 🔍 **Status**: Confirmed vulnerability (GHSA advisory). 🚩 **Risk**: High potential for wild exploitation due to low barrier to entry.

🔍 **Check**: Scan for `jsonata` dependency version. 📊 **Tool**: Use SAST/DAST tools detecting prototype pollution. 📝 **Code**: Look for untrusted JSONata expressions passed to `jsonata()` function.

✅ **Fixed**: Yes. 📦 **Patch**: Upgrade to **v2.0.4** or later. 🔗 **Source**: GitHub Release v2.0.4 & Security Advisory GHSA-fqg8-vfv7-8fj8.

🛑 **Workaround**: If unpatchable, **disable** JSONata processing for untrusted input. 🚫 **Sanitize**: Strictly validate/whitelist all expression inputs. 🧱 **Isolate**: Run in sandboxed environment if possible.

🔥 **Urgency**: CRITICAL. 🚨 **Priority**: P1. 🏃 **Action**: Patch immediately. CVSS 9.8 + Remote + No Auth = Immediate threat. 📢 **Alert**: Notify dev teams NOW.
