Security-related question about a possible exposed credential

[Emma-NYL]

Hello,

My name is Emma, I am conducting an academic study on possible credential exposure in public GitHub repositories.

While analyzing this repository, I found a string that may represent a credential. I'm including the code snippet below containing possible leakage. To avoid exposing sensitive information publicly, I marked the sensitive information.

Could you please help clarify whether the detected string is:

1. a real credential, or
2. a placeholder / example value?

Thank you for your time.

Code snippet (sensitive values masked):

    public static final String EXTERNAL_SWITCH_MGMT_DEVICE_STATE = "vsmdevicestate";
    // Would we need to have a capacity field for Cisco N1KV VSM? Max hosts managed by it perhaps? May remove this
    // later.
    public static final String EXTERNAL_SWITCH_MGMT_DEVICE_CAPACITY = "vsmdevicecapacity";
    public static final String CISCO_NEXUS_VSM_NAME = "vsmname";
    public static final String VSM_USERNAME = "vsmusername";
    public static final String VSM_PASSWORD = "vsmpassword";
    public static final String VSM_IPADDRESS = "vsmipaddress";
    public static final String VSM_MGMT_VLAN_ID = "vsmmgmtvlanid";
    public static final String VSM_PKT_VLAN_ID = "vsmpktvlanid";
    public static final String VSM_CTRL_VLAN_ID = "vsmctrlvlanid";
    public static final String VSM_STORAGE_VLAN_ID = "vsmstoragevlanid";
    public static final String VSM_DOMAIN_ID = "vsmdomainid";

Thank you in advance for your time - I really appreciate it!

Sincerely,
Emma
