CWEs ranked by how often they appear in real CVEs. The rationale describes how this control reduces exploitability of each weakness class.

CWE Name CVEs Why this control addresses it
CWE-200Exposure of Sensitive Information to an Unauthorized Actor11,000+Obscuring authentication feedback prevents exposure of sensitive information such as valid usernames or failure reasons to unauthorized actors.
CWE-209Generation of Error Message Containing Sensitive Information600+The control directly mitigates generation of error messages containing sensitive authentication details by requiring obscured feedback instead of verbose responses.
CWE-549Missing Password Field Masking16Obscuring feedback includes masking password input (e.g., asterisks), which addresses the weakness of missing password field masking.
