Matched remediation archetype

Information disclosure and sensitive data exposure

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

• Trace sensitive data through responses, errors, logs, metrics, traces, caches, exports, files, backups, and client bundles.
• Identify affected subjects, tenants, retention windows, access controls, and downstream copies without opening unnecessary sensitive records.
• Review metadata, timing, status, length, and existence signals as well as direct content disclosure.

Remediate safely

• Minimize collection and output, apply field-level authorization and redaction at a centralized boundary, and return generic external errors.
• Remove secrets and sensitive data from logs, artifacts, URLs, caches, and client-side bundles; rotate credentials that may have been exposed.
• Update the affected component and add synthetic-data tests for response, error, observability, and export paths.
