An issue discovered in Axios 0.8.1 through 1.5.1 inadvertently reveals the confidential XSRF-TOKEN stored in cookies by including it in the HTTP header X-XSRF-TOKEN for every request made to any host allowing attackers to view sensitive information.

Axios is vulnerable to DoS attack through lack of data size check
CVE-2025-58754 / GHSA-4hjh-wcwx-xvwj
More information
Details
Summary
When Axios runs on Node.js and is given a URL with the
data:scheme, it does not perform HTTP. Instead, its Node http adapter decodes the entire payload into memory (Buffer/Blob) and returns a synthetic 200 response.This path ignores
maxContentLength/maxBodyLength(which only protect HTTP responses), so an attacker can supply a very largedata:URI and cause the process to allocate unbounded memory and crash (DoS), even if the caller requestedresponseType: 'stream'.Details
The Node adapter (
lib/adapters/http.js) supports thedata:scheme. Whenaxiosencounters a request whose URL starts withdata:, it does not perform an HTTP request. Instead, it callsfromDataURI()to decode the Base64 payload into a Buffer or Blob.Relevant code from
[httpAdapter](https://redirect.github.com/axios/axios/blob/c959ff29013a3bc90cde3ac7ea2d9a3f9c08974b/lib/adapters/http.js#L231):The decoder is in
[lib/helpers/fromDataURI.js](https://redirect.github.com/axios/axios/blob/c959ff29013a3bc90cde3ac7ea2d9a3f9c08974b/lib/helpers/fromDataURI.js#L27):config.maxContentLengthorconfig.maxBodyLength, which only apply to HTTP streams.data:URI of arbitrary size can cause the Node process to allocate the entire content into memory.In comparison, normal HTTP responses are monitored for size, the HTTP adapter accumulates the response into a buffer and will reject when
totalResponseBytesexceeds[maxContentLength](https://redirect.github.com/axios/axios/blob/c959ff29013a3bc90cde3ac7ea2d9a3f9c08974b/lib/adapters/http.js#L550). No such check occurs fordata:URIs.PoC
Run with limited heap to force a crash:
Since Node heap is capped at 100 MB, the process terminates with an out-of-memory error:
Mini Real App PoC:
A small link-preview service that uses axios streaming, keep-alive agents, timeouts, and a JSON body. It allows data: URLs which axios fully ignore
maxContentLength,maxBodyLengthand decodes into memory on Node before streaming enabling DoS.Run this app and send 3 post requests:
Suggestions
Enforce size limits
For
protocol === 'data:', inspect the length of the Base64 payload before decoding. Ifconfig.maxContentLengthorconfig.maxBodyLengthis set, reject URIs whose payload exceeds the limit.Stream decoding
Instead of decoding the entire payload in one
Buffer.fromcall, decode the Base64 string in chunks using a streaming Base64 decoder. This would allow the application to process the data incrementally and abort if it grows too large.Severity

Axios is Vulnerable to Denial of Service via proto Key in mergeConfig
CVE-2026-25639 / GHSA-43fc-jf86-j433
More information
Details
Denial of Service via proto Key in mergeConfig
Summary
The
mergeConfigfunction in axios crashes with a TypeError when processing configuration objects containing__proto__as an own property. An attacker can trigger this by providing a malicious configuration object created viaJSON.parse(), causing complete denial of service.Details
The vulnerability exists in
lib/core/mergeConfig.jsat lines 98-101:When
propis'__proto__':JSON.parse('{"__proto__": {...}}')creates an object with__proto__as an own enumerable propertyObject.keys()includes'__proto__'in the iterationmergeMap['__proto__']performs prototype chain lookup, returningObject.prototype(truthy object)mergeMap[prop] || mergeDeepPropertiesevaluates toObject.prototypeObject.prototype(...)throwsTypeError: merge is not a functionThe

Control tests performed:
{"timeout": 5000}JSON.parse('{"__proto__": {"x": 1}}'){"headers": {"X-Test": "value"}}Attack scenario:
An application that accepts user input, parses it with
JSON.parse(), and passes it to axios configuration will crash when receiving the payload{"__proto__": {"x": 1}}.Impact
Denial of Service - Any application using axios that processes user-controlled JSON and passes it to axios configuration methods is vulnerable. The application will crash when processing the malicious payload.
Affected environments:
This is NOT prototype pollution - the application crashes before any assignment occurs.

Axios has Unrestricted Cloud Metadata Exfiltration via Header Injection Chain
CVE-2026-40175 / GHSA-fvcv-3m26-pcqx
More information
Details
Vulnerability Disclosure: Unrestricted Cloud Metadata Exfiltration via Header Injection Chain
Summary
The Axios library is vulnerable to a specific "Gadget" attack chain that allows Prototype Pollution in any third-party dependency to be escalated into Remote Code Execution (RCE) or Full Cloud Compromise (via AWS IMDSv2 bypass).
While Axios patches exist for preventing check pollution, the library remains vulnerable to being used as a gadget when pollution occurs elsewhere. This is due to a lack of HTTP Header Sanitization (CWE-113) combined with default SSRF capabilities.
Severity: Critical (CVSS 9.9)
Affected Versions: All versions (v0.x - v1.x)
Vulnerable Component:
lib/adapters/http.js(Header Processing)Usage of "Helper" Vulnerabilities
This vulnerability is unique because it requires Zero Direct User Input.
If an attacker can pollute
Object.prototypevia any other library in the stack (e.g.,qs,minimist,ini,body-parser), Axios will automatically pick up the polluted properties during its config merge.Because Axios does not sanitise these merged header values for CRLF (
\r\n) characters, the polluted property becomes a Request Smuggling payload.Proof of Concept
1. The Setup (Simulated Pollution)
Imagine a scenario where a known vulnerability exists in a query parser. The attacker sends a payload that sets:
2. The Gadget Trigger (Safe Code)
The application makes a completely safe, hardcoded request:
3. The Execution
Axios merges the prototype property
x-amz-targetinto the request headers. It then writes the header value directly to the socket without validation.Resulting HTTP traffic:
4. The Impact (IMDSv2 Bypass)
The "Smuggled" second request is a valid
PUTrequest to the AWS Metadata Service. It includes the requiredX-aws-ec2-metadata-token-ttl-secondsheader (which a normal SSRF cannot send).The Metadata Service returns a session token, allowing the attacker to steal IAM credentials and compromise the cloud account.
Impact Analysis
Cookie,Authorization) to pivot into internal administrative panels.Hostheaders to poison shared caches.Recommended Fix
Validate all header values in
lib/adapters/http.jsandxhr.jsbefore passing them to the underlying request function.Patch Suggestion:

Axios has a NO_PROXY Hostname Normalization Bypass that Leads to SSRF
CVE-2025-62718 / GHSA-3p68-rc4w-qgx5
More information
Details
Axios does not correctly handle hostname normalization when checking
NO_PROXYrules.Requests to loopback addresses like
localhost.(with a trailing dot) or[::1](IPv6 literal) skipNO_PROXYmatching and go through the configured proxy.This goes against what developers expect and lets attackers force requests through a proxy, even if
NO_PROXYis set up to protect loopback or internal services.According to RFC 1034 §3.1 and RFC 3986 §3.2.2, a hostname can have a trailing dot to show it is a fully qualified domain name (FQDN). At the DNS level,
localhost.is the same aslocalhost.However, Axios does a literal string comparison instead of normalizing hostnames before checking
NO_PROXY. This causes requests likehttp://localhost.:8080/andhttp://[::1]:8080/to be incorrectly proxied.This issue leads to the possibility of proxy bypass and SSRF vulnerabilities allowing attackers to reach sensitive loopback or internal services despite the configured protections.
PoC
Expected: Requests bypass the proxy (direct to loopback).
Actual: Proxy logs requests for
localhost.and[::1].Impact
Applications that rely on
NO_PROXY=localhost,127.0.0.1,::1for protecting loopback/internal access are vulnerable.Attackers controlling request URLs can:
