CVE-2026-25848 — AI Deep Analysis Summary

Q: What is this vulnerability? (Essence + Consequences)

🚨 **Essence**: Access Control Error in JetBrains Hub. ⚠️ **Consequences**: Bypasses authentication. Attackers can execute **admin operations**. Critical integrity & confidentiality risk.

Q: Root Cause? (CWE/Flaw)

🛡️ **CWE**: CWE-306 (Missing Authentication for Critical Function). 🔍 **Flaw**: Identity verification is skipped or bypassed in specific API endpoints or workflows.

Q: Who is affected? (Versions/Components)

🏢 **Vendor**: JetBrains. 📦 **Product**: Hub. 📅 **Affected**: Versions **before 2025.3.119807**. ✅ **Safe**: 2025.3.119807 and later.

Q: What can hackers do? (Privileges/Data)

💻 **Privileges**: Gains **Administrative** access. 📂 **Data**: Full control over team tools integration. 🔓 **Impact**: High Confidentiality & Integrity loss (CVSS I:H, C:H).

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

🔓 **Auth**: **None required** (PR:N). 🌐 **Network**: Remote (AV:N). 🎯 **Complexity**: Low (AC:L). 👤 **User Interaction**: None (UI:N). 📉 **Threshold**: **Very Low**. Easy to exploit.

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

🕵️ **Public Exp**: **No PoC** listed in data (pocs: []). 🌍 **Wild Exp**: Unconfirmed. ⚠️ **Risk**: Despite no public code, the low CVSS complexity makes targeted attacks likely.

Q: How to self-check? (Features/Scanning)

🔍 **Check**: Scan for JetBrains Hub instances. 📋 **Version**: Verify installed version is **< 2025.3.119807**. 🛡️ **Monitor**: Look for unauthorized admin API calls from external IPs.

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

🔧 **Fix**: Upgrade to **JetBrains Hub 2025.3.119807** or newer. 📢 **Source**: Official JetBrains Security Page. ✅ **Status**: Patched officially.

Q: What if no patch? (Workaround)

🚧 **Workaround**: 1. Restrict access via **Firewall/WAF** (Block external access to admin ports). 2. Enforce **MFA** if supported. 3. Isolate Hub in internal network.

Q: Is it urgent? (Priority Suggestion)

🔥 **Priority**: **HIGH**. 📊 **CVSS**: 8.6 (High). ⏳ **Urgency**: Patch immediately. Remote, unauthenticated admin access is a critical threat to team infrastructure.
