🛡️ Sentinel: [CRITICAL] Fix missing authorization on admin endpoints

.jules/sentinel.md

 **Vulnerability:** The document hashing routine in `DefaultDocumentConversionService` processed file streams without enforcing any maximum size limit on the bytes read. An attacker could exploit this by uploading a maliciously large stream (or exploiting a compression bomb if unzipping), exhausting system memory, CPU, or disk space (DoS).
 **Learning:** Checking the declared file size (e.g., `file.getSize()`) in initial validation is not always sufficient if the input stream itself can be spoofed or dynamically expanded during reading. The actual bytes read must be verified against bounds continuously.
 **Prevention:** Always enforce a strict, configurable size limit (e.g., `ConversionProperties.maxUploadSizeBytes`) within the `while` loop that reads from untrusted input streams. Track `totalRead` and throw an exception immediately if the limit is exceeded.
+## 2026-07-18 - Missing Authorization on Admin Endpoints
+**Vulnerability:** The `AdminController` endpoints (`/api/v1/admin/convert/jobs`, `deleteJob`, `retryDeadLettered`) completely lacked authentication and authorization checks, allowing unauthenticated or low-privilege users to view, delete, or retry conversion jobs across all tenants.
+**Learning:** Security controls like `TenantAccessService` must be explicitly applied to *every* controller handling sensitive endpoints, not just the primary user-facing ones. The `AdminController` was initially missed when authorization was enforced on `ConversionController`.
+**Prevention:** Always verify that every controller injects and utilizes the authorization enforcement mechanism (e.g., `TenantAccessService`) or use global security filters/interceptors to prevent missing authorization checks on newly added endpoints by default.
