DescriptionCVE.org

Axios is a promise-based HTTP client for the browser and Node.js. From 1.15.2 until 1.20.0, the Node HTTP adapter in lib/adapters/http.js supplies request options without an own createConnection value. A separate same-process prototype-pollution flaw places a function on Object.prototype.createConnection. Node resolves and invokes the inherited createConnection socket factory, allowing the attacker-controlled function to select the transport endpoint. The attacker endpoint can receive request headers and bodies, including credentials, and return attacker-controlled responses while the URL appears legitimate. This issue is fixed in version 1.20.0.

AnalysisAI

Credential and response tampering in Axios's Node HTTP adapter (lib/adapters/http.js) affects versions 1.15.2 through 1.19.x when a separate, same-process prototype-pollution flaw plants a function on Object.prototype.createConnection: because the adapter supplies request options without an own createConnection property, Node resolves and invokes the inherited function as the socket factory, redirecting the transport to an attacker-controlled endpoint that receives request headers and bodies (including credentials) and returns forged responses while the requested URL still appears legitimate. This is a confused-deputy gadget rather than a self-contained flaw - it is inert without a co-resident pollution primitive that can write a function onto Object.prototype, which is why the vendor CVSS 4.0 vector carries AT:P and why our independent assessment (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N) treats exploitation as contingent on that chain. …

Vulnerability AssessmentAI

Exploitation Exploitation is NOT possible against Axios alone: it strictly requires a separate, co-resident prototype-pollution vulnerability in the SAME Node.js process that can write a function to Object.prototype.createConnection. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a confused-deputy / unintended-proxy GADGET (CWE-441), NOT a self-contained vulnerability: Axios's Node HTTP adapter (lib/adapters/http.js) omits an own createConnection value, so if a SEPARATE same-process prototype-pollution flaw plants a function on Object.prototype.createConnection, Node resolves and invokes that inherited socket factory, letting the attacker redirect the transport endpoint. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Vendor-released patch: Axios 1.20.0 (release tag v1.20.0, commit d19040bda7a8be2f82c3c6e1a5bc03917daee39a, PR #11141) - upgrade all Node.js deployments of axios to 1.20.0 or later, and validate which transitive dependencies pin 1.15.2-1.19.x, since the gadget is inert only when no co-resident pollution primitive exists. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, inventory every Node.js service and build artifact that resolves Axios to a version between 1.15.2 and 1.19.x by checking package.json, lockfiles, and transitive dependencies (npm ls axios or existing SCA tooling), prioritizing internet-facing and credential-handling services, and flag any service that also carries a known prototype-pollution flaw as an elevated-risk exposure. …
