Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Unsafe template expansion in **Duo Agent Platform Flow** definitions. π₯ **Consequences**: Leads to **Denial of Service (DoS)** or **Remote Code Execution (RCE)** on the gateway.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: **CWE-1336** (Improper Neutralization of Special Elements used in a Template). The system fails to sanitize user-provided data before template expansion.
Q3Who is affected? (Versions/Components)
π¦ **Affected Versions**: GitLab AI Gateway **18.1.6**, **18.2.6**, **18.3.1** through **18.6.1**, **18.7.0**, and **18.8.0**. π’ **Vendor**: GitLab.
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: Can achieve **Full Control** (CVSS High). Specifically: **Code Execution** on the gateway and **System Crash** (DoS). Data integrity and confidentiality are also at risk.
Q5Is exploitation threshold high? (Auth/Config)
π **Exploitation Threshold**: **Medium**. Requires **Low Complexity** and **Network** access. β οΈ **Crucial**: Requires **Low Privileges** (Authenticated user) to submit the malicious Flow definition.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π΅οΈ **Public Exploit**: **No**. The `pocs` field is empty. No public Proof-of-Concept or wild exploitation code is currently available based on the data.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for GitLab AI Gateway instances running versions **18.1.6** to **18.8.0**. Check if **Duo Agent Platform Flow** definitions are exposed to untrusted users.
Q8Is it fixed officially? (Patch/Mitigation)
β **Official Fix**: **Yes**. Patch released on **2026-02-06**. Upgrade to **18.8.1** or later immediately. π **Published**: 2026-02-09.
Q9What if no patch? (Workaround)
π§ **No Patch Workaround**: Restrict access to **Duo Agent Platform Flow** definitions. Do not allow untrusted users to define or modify flows. Implement strict input validation on template strings.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **CRITICAL**. CVSS Score is **High** (likely 9.0+). RCE risk + Low Auth requirement = High Priority. Patch immediately upon upgrade to 18.8.1.
