Impact
A vulnerability exists in query plan execution within the gateway that may allow pollution of Object.prototype in certain scenarios. A malicious client may be able to pollute Object.prototype in gateway directly by crafting operations with field aliases and/or variable names that target prototype-inheritable properties. Alternatively, if a subgraph were to be compromised by a malicious actor, they may be able to pollute Object.prototype in gateway by crafting JSON response payloads that target prototype-inheritable properties.
Because Object.prototype is shared across the Node.js process, successful exploitation can affect subsequent requests to the gateway instance. This may result in unexpected application behavior, privilege escalation, data integrity issues, or other security impact depending on how polluted properties are subsequently consumed by the application or its dependencies. As of the date of this advisory, Apollo is not aware of any reported exploitation of this vulnerability.
Patches
Mitigations addressing prototype pollution exposure have been applied in @apollo/federation-internals, @apollo/gateway, and @apollo/query-planner versions 2.9.6, 2.10.5, 2.11.6, 2.12.3, and 2.13.2. Users are encouraged to upgrade to these versions or later at their earliest convenience.
Workarounds
A fully effective workaround is not available without a code change. As an interim measure, users who are unable to upgrade immediately may consider placing an input validation layer in front of the gateway to filter operations containing GraphQL names matching known Object.prototype pollution patterns (e.g., __proto__, constructor, prototype). Users should also ensure that subgraphs in their federated graph originate from trusted sources.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker needs basic access or low-level privileges. No user interaction is needed for the attacker to exploit this vulnerability. The vulnerability can affect other systems as well, not just the initial system. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a low impact on the availability of the system.
Active exploitation in the wild has been confirmed. Immediate patching or mitigation is required.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
