OpenSSF/OSV advisory MAL-2026-5608 confirms this npm version as malicious. claimora impersonates the jsonwebtoken library (auth0): package.json sets author to "auth0", points repository at a non-existent github.com/auth0/node-claimora, and re-exports the jsonwebtoken API surface (sign/verify/decode plus JsonWebTokenError/NotBeforeError/TokenExpiredError).

## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

claimora impersonates the jsonwebtoken library (auth0): package.json sets author to "auth0", points repository at a non-existent github.com/auth0/node-claimora, and re-exports the jsonwebtoken API surface (sign/verify/decode plus JsonWebTokenError/NotBeforeError/TokenExpiredError). README and LICENSE text are copied from node-jsonwebtoken. The main entry index.js loads decode.js, which at module top level invokes getThirdCookie() — this issues an axios GET to https://jsonkeeper.com/b/0GXBD, takes response.data.errCode (attacker-controlled JavaScript on a mutable public paste service), constructs \`new Function.constructor("require", errCode)\`, and invokes the resulting handler with \`require\`. Any process that requires claimora executes whatever code the operator of that paste currently serves, with full Node module access (filesystem, network, child\_process, env). The legitimate jsonwebtoken library performs zero network I/O; this clone adds a remote-fetch-and-eval path executed unconditionally on import.
