| Name | CVE-2026-44490 |
| Description | Axios is a promise based HTTP client for the browser and Node.js. Prior to 0.32.0 and 1.16.0, axios exposes two read-side prototype-pollution gadgets. When Object.prototype is polluted by an upstream dependency in the same process (e.g. lodash _.merge / CVE-2018-16487), axios silently picks up the polluted values. (1) lib/utils.js line 406 builds merge()'s accumulator as result = {}, so result[targetKey] (line 414) walks Object.prototype and the polluted bucket's own keys are copied into the merged headers and ride out on the wire. (2) lib/core/mergeConfig.js line 26 builds the hasOwnProperty descriptor as a plain-object literal. Object.defineProperty reads descriptor.get/descriptor.set via the prototype chain, so a polluted Object.prototype.get or Object.prototype.set makes the call throw TypeError synchronously on every axios request. This vulnerability is fixed in 0.32.0 and 1.16.0. |

Notes
[trixie] - node-axios <no-dsa> (Minor issue)
[bookworm] - node-axios <postponed> (Minor issue; prototype-pollution gadget in utils.merge(), needs a separate pollution primitive in the same process)
[bullseye] - node-axios <postponed> (Minor issue; prototype-pollution gadget in utils.merge(), needs a separate pollution primitive in the same process)
