Description
Apollo Studio Embeddable Explorer & Embeddable Sandbox are website embeddable software solutions from Apollo GraphQL. Prior to Apollo Sandbox version 2.7.2 and Apollo Explorer version 3.7.3, a cross-site request forgery (CSRF) vulnerability was identified. The vulnerability arises from missing origin validation in the client-side code that handles window.postMessage events. A malicious website can send forged messages to the embedding page, causing the victim’s browser to execute arbitrary GraphQL queries or mutations against their GraphQL server while authenticated with the victim’s cookies. This issue has been patched in Apollo Sandbox version 2.7.2 and Apollo Explorer version 3.7.3.

Executive Summary

This vulnerability is a cross-site request forgery (CSRF) issue in Apollo Studio Embeddable Explorer and Embeddable Sandbox before versions 3.7.3 and 2.7.2 respectively. It occurs because the client-side code handling window.postMessage events does not validate the origin of messages. As a result, a malicious website can send forged messages to the embedding page, causing the victim's browser to execute arbitrary GraphQL queries or mutations against their GraphQL server while authenticated with the victim's cookies.

Impact Analysis

This vulnerability can allow an attacker to perform unauthorized GraphQL queries or mutations on behalf of an authenticated user without their consent. This could lead to unauthorized data access or modification, potentially compromising the confidentiality and integrity of data handled by the GraphQL server.

Mitigation Strategies

Update Apollo Sandbox to version 2.7.2 or later and Apollo Explorer to version 3.7.3 or later to apply the patch that fixes the CSRF vulnerability caused by missing origin validation in the client-side code.
