DescriptionGitHub Advisory
Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, when responseType: 'stream' is used, Axios returns the response stream without enforcing maxContentLength. This bypasses configured response-size limits and allows unbounded downstream consumption. This vulnerability is fixed in 1.15.1 and 0.31.1.
AnalysisAI
Axios HTTP client prior to version 1.15.1 (1.x branch) and 0.31.1 (0.x branch) fails to enforce maxContentLength limits when responseType is set to 'stream', allowing attackers to cause denial of service by streaming unbounded response payloads that bypass configured size restrictions. The vulnerability affects both browser and Node.js environments and requires no authentication or user interaction to exploit.

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target application to explicitly set responseType: 'stream' when making HTTP requests with Axios. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 5.3 with AV:N/AC:L/PR:N/UI:N indicates network-accessible denial of service with low attack complexity and no privilege or interaction requirements. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts an HTTP request to a vulnerable application configured with Axios responseType: 'stream' and a maxContentLength limit (e.g., 10MB). The attacker's server sends an HTTP response with a Content-Length header claiming a small size (1MB) but streams gigabytes of data. … |
| Remediation | Upgrade to Axios 1.15.1 or later for the 1.x branch, or to 0.31.1 or later for the 0.x branch. … Detailed patch versions, workarounds, and compensating controls in full report. |
