CVE-2025-47275 — AI Deep Analysis Summary

Q: Root Cause? (CWE/Flaw)

🛡️ **Root Cause**: **CWE-287** (Improper Authentication). 🔍 **Flaw**: The `CookieStore` implementation allows session cookies to be guessed or brute-forced due to insufficient entropy or validation mechanisms.

Q: Is exploitation threshold high? (Auth/Config)

⚡ **Threshold**: **LOW**. 🌐 **Network**: Attack Vector is **Network** (AV:N). 🔑 **Auth**: **None** required (PR:N). 👁️ **UI**: **None** required (UI:N). Easy to exploit remotely.

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

💣 **Public Exploit**: **No**. 📝 **PoCs**: The `pocs` list is empty in the data. 🌍 **Wild Exploitation**: No reports of widespread automated exploitation yet, but the low barrier makes it risky.

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