credential leakage

About this tag
Credential leakage refers to the unintentional exposure of sensitive authentication data such as passwords, tokens, API keys, or client secrets. On WindowsForum.com, discussions cover a range of real-world incidents and vulnerabilities, including CVE-2026-23370 where Dell Linux WMI Sysman hex-dumped plaintext passwords, CVE-2025-61594 in the Ruby uri gem that leaked credentials via URI combination, and CVE-2024-45336 in Go's net/http client that could leak Authorization headers during redirects. Other topics include local cleartext storage in Microsoft PC Manager (CVE-2025-49728), exposed Azure AD credentials in appsettings.json files, and LNK file tricks that can hide malicious execution. These examples highlight how credential leakage can occur through software bugs, misconfigurations, or UI spoofing, and emphasize the importance of patching, secret management, and secure coding practices.
