Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: CVE-2026-26190 is an **Access Control Error** in Milvus. ๐ **Consequences**: Unauthenticated access leads to **Arbitrary Expression Execution**. Total loss of confidentiality, integrity, and availability!
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: **CWE-306** (Missing Authentication for Critical Function). The default TCP port **9091** lacks proper authentication checks, allowing bypass. ๐
Q3Who is affected? (Versions/Components)
๐ฅ **Affected**: **Milvus** (Cloud-native vector DB). Versions **< 2.5.27** AND **< 2.6.10**. If you run older builds, you are at risk! โ ๏ธ
๐ **Exploitation Threshold**: **LOW**. CVSS: **AV:N/AC:L/PR:N**. No authentication required. No user interaction needed. Just network access to port 9091. ๐ฏ
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐งช **Public Exploit**: **No PoC provided** in this dataset. However, the flaw is logical (missing auth). Exploitation is theoretically trivial for skilled attackers. ๐ต๏ธโโ๏ธ
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for open **TCP Port 9091**. Check Milvus version against **2.5.27** and **2.6.10**. Verify if port 9091 responds without credentials. ๐ก
Q8Is it fixed officially? (Patch/Mitigation)
โ **Official Fix**: **YES**. Patched in **v2.5.27** and **v2.6.10**. Upgrade immediately! See GitHub Advisory GHSA-7ppg-37fh-vcr6. ๐ฆ
Q9What if no patch? (Workaround)
๐ง **No Patch Workaround**: **Block Port 9091** externally via Firewall/Security Group. Do NOT expose it to the internet. Restrict access to trusted IPs only. ๐งฑ
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: **CRITICAL**. CVSS Score **9.8** (High). Remote Code Execution potential. Patch **IMMEDIATELY** or isolate the service. Do not wait! โณ
