node-axios: Axios is a promise based HTTP client for the browser and Node.js
CVE-2026-42040 is fixed in node-axios on 1 platform by DEBIAN-CVE-2026-42040 (version 1.15.2-1), released May 15, 2026. It is not reported as exploited. Patch Radar priority: Routine.
Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, the encode() function in lib/helpers/AxiosURLSearchParams.js contains a character mapping (charMap) at line 21 that reverses the safe percent-encoding of null bytes. After encodeURIComponent('\x00') correctly produces the safe sequence %00, the charMap entry '%00': '\x00' converts it back to a raw null byte. Primary impact is limited because the standard axios request flow is not affected. This vulnerability is fixed in 1.15.1 and 0.31.1.
