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-79Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')52,800+Output validation against expected content can reject or sanitize script content in generated web pages, reducing XSS exploitability.
CWE-200Exposure of Sensitive Information to an Unauthorized Actor11,000+Filtering output to only permitted content stops unintended disclosure of sensitive information to unauthorized actors.
CWE-532Insertion of Sensitive Information into Log File1,400+Checking application output against expected content catches insertion of sensitive values into log streams or files.
CWE-209Generation of Error Message Containing Sensitive Information600+Validation ensures error messages contain only expected, non-sensitive content and blocks leakage via verbose errors.
CWE-116Improper Encoding or Escaping of Output500+Validating that output matches expected content directly mitigates failures to properly encode or escape data for its destination context.
CWE-117Improper Output Neutralization for Logs100+Requiring output to conform to expected content prevents unneutralized data from reaching logs.
