Technical Analysis
This vulnerability in Apache APISIX 3.17.0 involves inefficient algorithmic complexity in the graphql-limit-count routes. An attacker can send a small request that causes a gateway worker process to become pinned at full CPU utilization, potentially leading to denial of service conditions. The vulnerability is identified as CWE-407 (Inefficient Algorithmic Complexity). The vendor recommends upgrading to version 3.18.0 to resolve the issue.
Potential Impact
Successful exploitation results in a denial of service condition by causing a gateway worker to consume 100% CPU for an extended time, which can degrade or disrupt service availability. There is no indication of privilege escalation, data disclosure, or other impacts.
Mitigation Recommendations
Users should upgrade Apache APISIX from version 3.17.0 to version 3.18.0, where this vulnerability is fixed. No other mitigation or temporary workaround is specified.
