Apollo Router Operation Limits Vulnerable to Bypass via Integer Overflow

The Apollo Router Core is a configurable, high-performance graph router written in Rust to run a federated supergraph that uses Apollo Federation 2. Prior to 1.61.2 and 2.1.1, the operation limits plugin uses unsigned 32-bit integers to track limit counters (e.g. for a query's height). If a counter exceeded the maximum value for this data type (4,294,967,295), it wrapped around to 0, unintentionally allowing queries to bypass configured thresholds. This could occur for large queries if the payload limit were sufficiently increased, but could also occur for small queries with deeply nested and reused named fragments. This has been remediated in apollo-router versions 1.61.2 and 2.1.1.

内存缓冲区边界内操作的限制不恰当

Apollo Router Core 缓冲区错误漏洞

Apollo Router Core是Apollo社区的一个路由器核心应用程序。 Apollo Router Core 1.61.2之前版本和2.1.1之前版本存在缓冲区错误漏洞，该漏洞源于操作限制计数器溢出，可能导致查询绕过阈值。
