Valtimo has sensitive data exposure through HTTP request/response logging in LoggingRestClientCustomizer

描述

### Summary The `LoggingRestClientCustomizer` in the `web` module automatically intercepts all outgoing HTTP calls made via Spring's `RestClient` and logs the full request body, response body, and response headers. When an error response is received, this information is included in the thrown `HttpClientErrorException` message, which is logged at ERROR level by Spring's default exception handling — regardless of the application's DEBUG log level setting. ### Impact The logged data can contain highly sensitive information including: - Authentication credentials (JWT tokens, API keys, OAuth tokens) in request bodies or response headers - Personal data (BSN, email addresses, case details) in request/response bodies - Session tokens in `Set-Cookie` response headers This data is exposed to: - Anyone with access to application logs (stdout/log files) - Users with access to logging aggregation tools (e.g. Grafana/Loki) - Any Valtimo user with the admin role, through the built-in logging module (since Valtimo 12.5.0) Leaked authentication credentials could be used to impersonate the Valtimo application against the target external API (e.g. ZGW services), compromising that API's security boundary. Related: GHSA-hfrg-mcvw-8mch (similar sensitive data exposure in InboxHandlingService) ### Affected Code `com.ritense.valtimo.web.logging.LoggingRestClientCustomizer#intercept` in the `web` module. ### Patched Versions The vulnerability is fixed in: - **12.33.0** (v12 release line) — see PR #600 - **13.26.0** (v13 release line) — see PR #599 The fix removes the request/response report, headers, and response body from the `HttpClientErrorException` constructor; only the HTTP status code and status text remain. The full request/response report is still emitted at DEBUG level (disabled in production). ### Mitigation If you cannot upgrade to a patched version immediately, consider: - Restricting access to application logs and the Valtimo logging module - Adjusting the log level for `com.ritense.valtimo.web.logging` to WARN or higher (note: this only mitigates the DEBUG logging path; error responses still leak data via the exception message)
