No exploitable findings

API input validation · Completed clean

Executive summary

The test did not identify a reproducible security vulnerability within the authorized scope. Input validation and error handling were tested across the public API in an isolated copy of the application.

The run covered 24 endpoints and issued 146 bounded requests against malformed, oversized, and unexpected values. Candidate responses were replayed before being dismissed.

Scope

• Application: customer-api
• Commit: 71ca4e8
• Test classes: request parsing, input validation, and error handling
• Internet egress: blocked

Test results

The application rejected invalid identifiers, unsupported content types, malformed JSON, unexpected object fields, and values outside documented limits. Responses did not expose stack traces, database errors, or internal file paths.

Two anomalous 500 responses were investigated. Deterministic replay attributed both to the disposable environment reaching its configured request budget; neither response was reproducible after the environment was restored.

Recommendations

No remediation is required from this run. Retain the current schema validation and add the exercised malformed-request cases to the application’s regression suite.

Limitations

No findings means no vulnerability was reproduced within this run’s tested commit, environment, scope, and time window. It does not establish that the application is free of vulnerabilities.
