## What is CVE-2026-101905?

CVE-2026-101905 is a high-severity code injection vulnerability in axios, published on 28 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

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.

Weakness: CWE-441 (Unintended Proxy or Intermediary), CWE-1321 (Improperly Controlled Modification of Object Prototype Attributes)

Check this codebase for CVE-2026-101905 and fix it if it is affected.

What it is: CVE-2026-101905 is a high-severity code injection vulnerability in axios, published on 28 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-101905 exists.

Affected packages and fixed versions:
- axios (npm): affected from 1.15.2; fixed in 1.20.0
- axios (npm): affected from 1.15.2; fixed in 1.20.0

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
