Summary
axios versions >=1.13.0 (Node.js HTTP adapter) fail to enforce the configured maxBodyLength limit on streamed request bodies when requests are sent with httpVersion: 2.
Because Node's HTTP/2 request API does not honor the maxBodyLength option and axios's byte-counting stream wrapper is gated on maxRedirects === 0, an attacker who controls a stream passed to axios can cause the application to transmit outbound data exceeding the configured finite maxBodyLength.
Impact is limited to resource consumption and policy bypass (excess egress, upstream quota consumption, limited availability); it does not enable code execution, credential disclosure, or request-destination control. Calls using the default maxBodyLength: -1 and browser adapters are not affected.
A flaw was found in axios, a popular JavaScript library for making HTTP requests. This allows a remote attacker, by controlling the input stream, to send an arbitrarily large amount of data.
The primary impact is excessive resource consumption, increased network egress, and potential denial of service for the affected application. Red Hat severity: Moderate — CVSS 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).
Weakness: CWE-770.
Affected products named by the advisory: Red Hat Hardened Images; Migration Toolkit for Applications 8; Migration Toolkit for Containers; Multicluster Engine for Kubernetes; and 15 more.
