AI-suggested

The vulnerability was fixed in the 2026-05-07 release of Pi.Alert. Users should upgrade to version 2026-05-07 or later to remediate this issue. Additionally, enabling PIALERT_WEB_PROTECTION may reduce exposure by requiring authentication, but the primary mitigation is applying the fixed version. Patch status is not explicitly confirmed beyond the stated fix date; users should consult the vendor for current remediation guidance.

Description

CVE-2026-44888 is a critical code injection vulnerability in leiweibau Pi. Alert versions prior to 2026-05-07. The SaveConfigFile() endpoint improperly writes user-supplied numeric configuration values directly into a configuration file (pialert.conf) without validation. This file is executed every few minutes by a background Python process, allowing unauthenticated attackers to inject arbitrary Python code and achieve OS-level remote code execution. By default, installations have no web protection enabled, requiring no credentials to exploit. The vulnerability has a CVSS score of 9.8 and was fixed on 2026-05-07.
