Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Apollo Federation < 2.13.2 has a **Prototype Pollution** flaw in the query plan execution.β¦
π‘οΈ **Root Cause**: **CWE-1321** (Prototype Pollution). The gateway's query plan execution fails to sanitize inputs, allowing attackers to inject properties into the global object prototype. π§¬
Q3Who is affected? (Versions/Components)
π¦ **Affected**: Apollo Federation versions **< 2.9.6**, **< 2.10.5**, **< 2.11.6**, **< 2.12.3**, and **< 2.13.2**. π Includes `federation-internals` component.
Q4What can hackers do? (Privileges/Data)
π **Impact**: High! CVSS **8.6**. Attackers can achieve **High Confidentiality & Integrity** impact. They can modify global object behavior, potentially bypassing security checks or executing arbitrary code. β οΈ
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: **Medium**. Requires **Low Privileges** (PR:L) and **Low Complexity** (AC:L). No User Interaction needed (UI:N). Network accessible (AV:N). βοΈ
Q6Is there a public Exp? (PoC/Wild Exploitation)
π΅οΈ **Exploit**: **No public PoC** listed in data. However, the vulnerability type (Prototype Pollution) is well-known. Wild exploitation is possible if attackers understand the specific injection vector. π«
Q7How to self-check? (Features/Scanning)
π **Check**: Scan for Apollo Federation versions < 2.13.2. Look for GraphQL endpoints accepting complex nested JSON payloads. Monitor for unexpected `Object.prototype` modifications in logs. π
Q8Is it fixed officially? (Patch/Mitigation)
β **Fix**: **Yes**. Official patches available for all affected version branches. Update to **2.9.6+**, **2.10.5+**, **2.11.6+**, **2.12.3+**, or **2.13.2+**. π οΈ
Q9What if no patch? (Workaround)
π§ **Workaround**: If patching is delayed, implement strict **input validation** on GraphQL queries. Sanitize JSON payloads before they reach the query planner. Restrict access to the gateway. π
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **HIGH**. CVSS 8.6 + Prototype Pollution = Critical risk. Patch immediately! Do not wait. πββοΈπ¨
