Description

The npm package uol-simple-api-futebol versions 4.6.3, 4.6.4, and 4.7.0 contains malicious code that exfiltrates the entire environment variables of the host process to an attacker-controlled server via an unencrypted HTTP POST request. This includes sensitive credentials such as cloud keys, database passwords, API tokens, and other secrets. The exfiltration is concealed within a misleadingly named internal function and errors during this process are silently ignored, increasing the risk of unnoticed data leakage.

Impact

Sensitive environment variables such as AWS keys, database passwords, npm tokens, and API keys are exfiltrated to an attacker-controlled server, potentially leading to unauthorized access to cloud resources, databases, and other services. This represents a critical confidentiality breach with high potential for downstream compromise of infrastructure and data.

Defensive guidance

Users should immediately discontinue use of the affected versions (4.6.3, 4.6.4, 4.7.0) of uol-simple-api-futebol. Review and rotate any credentials or secrets that may have been exposed. Monitor for suspicious activity related to compromised keys. Consider using alternative trusted packages and verify package integrity before use.

Summary

The uol-simple-api-futebol package's main function getJogos() calls an internal helper prepareCacheMatchs which sends the full process.env object, labeled as 'test', along with the request URL to a hardcoded external endpoint over plain HTTP. This endpoint is unrelated to the package's stated purpose. The malicious code is obfuscated by being appended as a single dense line under a misleading name and wrapped in try/catch blocks that suppress errors. Because process.env typically contains sensitive environment variables including cloud credentials and API keys, every user invoking the documented API inadvertently leaks these secrets to an attacker-controlled server.
