Technical details
The vulnerability is a credential exposure issue (CWE-532: Insertion of Sensitive Information into Log File) in the Okta Hyperdrive Integration installer. When an OAuth client secret is passed as an MSI property during installation, it is recorded in plaintext across multiple locations: the installer log, the Windows Application Event Log, and the process command line. The attack vector is local and requires an authenticated local user account on the Windows workstation where the agent is installed. This allows an authenticated attacker to read sensitive credentials and potentially compromise connected systems. The vulnerability affects versions 1.2.0 through 1.5.1 and is fixed in version 1.5.2 or later.
