CVE-2026-27626 โ€” AI Deep Analysis Summary

CVSS 10.0 ยท Critical

Q1What is this vulnerability? (Essence + Consequences)

๐Ÿšจ **Essence**: OliveTin suffers from **OS Command Injection**. ๐Ÿ“‰ **Consequences**: Unauthenticated Remote Code Execution (RCE). Attackers can execute arbitrary commands on the host system.

Q2Root Cause? (CWE/Flaw)

๐Ÿ›ก๏ธ **Root Cause**: **CWE-78** (OS Command Injection). The flaw lies in **insufficient shell mode security checks**. User input is likely passed directly to the shell without proper sanitization.

Q3Who is affected? (Versions/Components)

๐Ÿ“ฆ **Affected**: **OliveTin** (Open Source Web App). ๐Ÿ“… **Versions**: **3000.10.0 and earlier**. If you are running this version or older, you are at risk.

Q4What can hackers do? (Privileges/Data)

๐Ÿ’€ **Attacker Capabilities**: Full **Remote Code Execution**. Can access sensitive data, modify system files, and potentially pivot to other internal systems. High impact on Confidentiality, Integrity, and Availability.

Q5Is exploitation threshold high? (Auth/Config)

๐Ÿ”‘ **Exploitation Threshold**: **Low**. CVSS indicates **AV:N** (Network) and **AC:L** (Low Complexity). However, it requires **PR:L** (Low Privileges) to access the interface initially. No UI interaction needed.

Q6Is there a public Exp? (PoC/Wild Exploitation)

๐Ÿ” **Public Exploit**: **None listed** in current data. No PoC or wild exploitation code is currently available in the provided references. Stay vigilant for new releases.

Q7How to self-check? (Features/Scanning)

๐Ÿ”Ž **Self-Check**: Scan for **OliveTin** services on port **8000** (default) or configured ports. Check version headers. Look for endpoints accepting user input that triggers shell commands.

Q8Is it fixed officially? (Patch/Mitigation)

๐Ÿ› ๏ธ **Official Fix**: **Yes**. Refer to the GitHub Security Advisory: **GHSA-49gm-hh7w-wfvf**. Update to the patched version immediately. Check the vendor's official release notes.

Q9What if no patch? (Workaround)

๐Ÿšง **No Patch Workaround**: **Isolate** the service. Restrict network access to trusted IPs only. **Disable** shell execution features if possible. Monitor logs for suspicious command patterns.

Q10Is it urgent? (Priority Suggestion)

โšก **Urgency**: **CRITICAL**. CVSS Score is **High** (likely 9.8+). RCE via network is a top-priority fix. Patch immediately to prevent system compromise.
