CWE-345 is Insufficient Verification of Data Authenticity. The flaw arises when the product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data. The database currently holds 310 vulnerabilities mapped to CWE-345 and none of them are in the CISA Known Exploited Vulnerabilities catalog.
A short verification protects the official data source and prevents automated AI abuse.

| Automated Static Analysis | Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.) | High |
