CVE-2026-94250 · Severity: info · Published 2026-10-01

Apache APISIX is an API gateway that manages and routes HTTP traffic for cloud services. The batch-requests plugin, when exposed publicly, can be exploited by an unauthenticated attacker to send extremely large batch requests that exhaust worker memory, causing an out-of-memory condition and gateway outage. An attacker can disable the entire API gateway without requiring any authentication.

## How to fix

- Fixed in 3.19.0

## Technical details

The batch-requests plugin in Apache APISIX lacks resource limits or request throttling, allowing attackers to submit unbounded batch requests. An unauthenticated, network-based attacker can craft oversized requests to a publicly exposed batch endpoint with minimal preconditions, triggering out-of-memory exhaustion in gateway worker processes. The vulnerability is fixed in version 3.19.0.

## Affected products

- Apache APISIX 1.3.0 through 3.18.0
