CVE-2026-30893 — AI Deep Analysis Summary

🚨 **Essence**: Wazuh suffers from a **Path Traversal** flaw in cluster sync extraction. 📉 **Consequences**: This allows **Arbitrary File Write** and potentially **Remote Code Execution (RCE)**. Critical integrity breach!

🛡️ **Root Cause**: **CWE-22** (Improper Limitation of a Pathname to a Restricted Directory). The system fails to sanitize input during cluster synchronization, allowing directory traversal sequences (`../`).

👥 **Affected**: **Wazuh** versions **4.4.0** up to **4.14.4** (exclusive). If you are running any version in this range, you are vulnerable. 📅 **Published**: 2026-04-29.

💀 **Attacker Capabilities**: With access, hackers can write files anywhere the service has permissions. This leads to **High Integrity** and **High Availability** impact. They can execute arbitrary code on the server! ⚡

🔐 **Exploitation Threshold**: **Medium**. CVSS indicates **PR:H** (Privileges Required: High). The attacker needs valid authentication credentials to trigger the cluster sync path traversal.…

📜 **Public Exploit**: **No**. The `pocs` field is empty. No public Proof-of-Concept (PoC) or wild exploitation scripts are currently available. 🚫

🔍 **Self-Check**: Scan your environment for Wazuh versions **4.4.0 - 4.14.4**. Check if cluster synchronization is enabled. Look for unauthorized file modifications in Wazuh directories. 🕵️‍♂️

✅ **Official Fix**: **Yes**. The vulnerability is fixed in **Wazuh v4.14.4**. Refer to the GitHub release notes and security advisory (GHSA-m8rw-v4f6-8787) for the patch. 🛠️

🚧 **No Patch Workaround**: If you cannot upgrade immediately, **disable cluster synchronization** if not strictly necessary. Restrict network access to the Wazuh manager. Monitor file integrity alerts closely. 🛑

🔥 **Urgency**: **HIGH**. Despite requiring auth, the impact is **Critical** (RCE/Arbitrary Write). CVSS Score reflects High Availability/Integrity loss. Patch to **v4.14.4+** immediately! 🏃‍♂️💨
