Apache APISIX: Unauthenticated CPU-exhaustion DoS (CVE-2026-75005)
Description
Apache APISIX version 3.17.0 contains an Inefficient Algorithmic Complexity vulnerability that allows an unauthenticated attacker to cause a CPU exhaustion denial-of-service (DoS) condition. This occurs specifically in graphql-limit-count routes where a single small request can cause a gateway worker to consume 100% CPU for an extended period. The issue is fixed in version 3.18.0.

Technical Analysis
CVE-2026-75005 is an Inefficient Algorithmic Complexity vulnerability (CWE-407) in Apache APISIX 3.17.0. The flaw allows an unauthenticated attacker to send a crafted request to graphql-limit-count routes, causing a gateway worker process to be pinned at 100% CPU usage for a prolonged time, resulting in a denial-of-service condition. This vulnerability is addressed by upgrading to Apache APISIX version 3.18.0.
Potential Impact
An attacker can cause a denial-of-service by exhausting CPU resources on the gateway worker handling graphql-limit-count routes, potentially disrupting service availability. No authentication is required to trigger this condition.
Mitigation Recommendations
Users should upgrade Apache APISIX to version 3.18.0 or later, where this vulnerability is fixed. Since a patch is available and the vendor has released a fixed version, applying this official fix is the recommended remediation.
