🛡️ MAL-2026-4772 — txdpy

Malicious code in txdpy (PyPI)

Source: amazon-inspector

The package exports a 发送邮件 (send_email) function whose default sender, recipient, and SMTP auth code are hardcoded to the author's QQ account. In txdpy/发送邮件.py lines 14-17, sender_email defaults to '[email protected]', receiver_email defaults to '[email protected]', and password defaults to the embedded QQ SMTP authorization code. A caller invoking this documented API with the minimal signature (subject and body only) silently delivers their message content to the author's inbox via smtp.qq.com using the author's credentials — the API's advertised purpose (generic email sending) does not match its actual behavior (relaying to a fixed author-controlled mailbox). The function is re-exported from __init__.py, making it part of the package's public surface. Additionally, txdpy/翻译.py:18-20 ships the author's Baidu Translate API credentials (appid 20220712001270949 + secret_key) — author self-harm rather than installer harm, but corroborates a pattern of careless credential handling. A separate quality issue: pyndjs.py:74 evaluates os.popen('where node') as a function default argument, causing shell execution at import time.
