DescriptionNVD
Yubico libfido2 before 1.17.0, python-fido2 before 2.2.0, and yubikey-manager before 5.9.1 have an unintended DLL search path.
AnalysisAI
Untrusted DLL search path vulnerability in Yubico libfido2 before 1.17.0, python-fido2 before 2.2.0, and yubikey-manager before 5.9.1 allows local attackers to achieve privilege escalation or code execution by placing a malicious DLL in a directory searched before the legitimate library location. The vulnerability requires local access and high complexity conditions but affects three widely-used FIDO2 authentication libraries; no public exploit code identified at time of analysis.
