Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Hot Chocolate's recursive descent parser lacks a **recursion depth limit**. π **Consequences**: This leads to **Stack Overflow Exceptions** and immediate **Process Termination** (DoS).
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: **CWE-674** (Uncontrolled Recursion). The parser fails to restrict how deep recursive calls can go, causing resource exhaustion.
π **Attacker Action**: Can trigger a **Denial of Service (DoS)**. By sending crafted GraphQL queries, hackers cause the server to crash via stack overflow. No data theft, just **Service Down**.
Q5Is exploitation threshold high? (Auth/Config)
π **Exploitation Threshold**: **LOW**. CVSS indicates **AV:N** (Network), **AC:L** (Low Complexity), **PR:N** (No Privileges Required), **UI:N** (No User Interaction). Easy to exploit remotely.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π΅οΈ **Public Exploit**: **No**. The `pocs` field is empty. While the vulnerability is known, no specific Proof-of-Concept code or wild exploitation tools are currently public.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan your backend for **Hot Chocolate** libraries. Check the `package.json` or dependency tree for versions older than the fixed releases listed above.
Q8Is it fixed officially? (Patch/Mitigation)
β **Official Fix**: **YES**. Patches are available in: **12.22.7**, **13.9.16**, **14.3.1**, and **15.1.14**. See GitHub Security Advisories for details.
Q9What if no patch? (Workaround)
π§ **No Patch Workaround**: Implement a **Query Depth Limit** or **Query Complexity Analysis** middleware in your GraphQL schema to restrict recursion depth manually before it hits the parser.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **HIGH**. CVSS Score is **7.5** (High). Since it requires no auth and causes immediate crash, patch immediately to prevent service disruption.
