CVE-2025-25014 — AI Deep Analysis Summary

Q: Root Cause? (CWE/Flaw)

🔍 **Root Cause:** **Prototype Pollution** (CWE-1321). 🛠️ **Flaw:** Improper handling of user input in Machine Learning and Reporting APIs allows attackers to pollute JavaScript prototypes, leading to code execution.

Q: Who is affected? (Versions/Components)

📦 **Affected:** Elastic Kibana. 📅 **Versions:** • **8.3.0 to 8.17.5** • **8.18.x** (specifically before 8.18.1) • **9.0.0** (before 9.0.1). ⚠️ *Check your version immediately!*

Q: Is there a public Exp? (PoC/Wild Exploitation)

💣 **Public Exploits:** ✅ **Yes.** Multiple PoCs available on GitHub (e.g., `davidxbors`, `B1ack4sh`). 🔧 **Status:** Detection PoCs exist. RCE PoCs are circulating. ⚠️ *Wild exploitation is likely imminent.*

Q: Is it fixed officially? (Patch/Mitigation)

🛡️ **Official Fix:** ✅ **Yes.** Elastic released security updates. 📥 **Patch Versions:** • **Kibana 8.17.6** • **Kibana 8.18.1** • **Kibana 9.0.1** 🔗 *See Elastic ESA-2025-07 advisory.*
