From 8b2c7a407c098c3cbbdb022cc26d7b6127dc5d11 Mon Sep 17 00:00:00 2001 From: seonghobae <8172694+seonghobae@users.noreply.github.com> Date: Tue, 6 Oct 2026 22:18:56 +0000 Subject: [PATCH 1/4] =?UTF-8?q?=F0=9F=9B=A1=EF=B8=8F=20Sentinel:=20[CRITIC?= =?UTF-8?q?AL]=20Add=20authentication=20to=20admin=20endpoints?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Severity: CRITICAL Vulnerability: The admin endpoints (`/api/v1/admin/convert/jobs`, etc) lacked tenant access enforcement, allowing unauthorized cross-tenant job access. Impact: Any unauthenticated or cross-tenant attacker could retrieve, delete, or manipulate the status of conversion jobs belonging to other tenants. Fix: Injected `TenantAccessService` and strictly required the `admin:operate` permission on all administrative handlers. Verification: Ran `mvn verify` and checked that Checkstyle / test coverage passed successfully.

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. +## 2026-10-06 - Missing Authentication on Admin Endpoint +**Vulnerability:** Admin endpoints (`/api/v1/admin/convert/jobs`, `/api/v1/admin/convert/jobs/{jobId}`, `/api/v1/admin/convert/jobs/{jobId}/retry`) in `AdminController.java` did not enforce any authentication or authorization checks. Any user could access or modify all conversion jobs across tenants. +**Learning:** Endpoints mapped to `/admin` or performing privileged operations must explicitly require high-privilege claims. Spring Security is not configured automatically for every custom controller. The `TenantAccessService` must be explicitly injected and invoked on every handler method. +**Prevention:** Always verify that internal administrative endpoints or broad tenant-spanning operations enforce an explicit permission (e.g., `admin:operate`) via a security guard service (like `TenantAccessService.require`) and explicitly pass the HTTP headers in the request to validate the claims. diff --git a/src/main/java/com/clearfolio/viewer/auth/TenantPermissions.java b/src/main/java/com/clearfolio/viewer/auth/TenantPermissions.java index 4f9c6a685..717e59a7d 100644 --- a/src/main/java/com/clearfolio/viewer/auth/TenantPermissions.java +++ b/src/main/java/com/clearfolio/viewer/auth/TenantPermissions.java @@ -55,6 +55,11 @@ public final class TenantPermissions { */ public static final String ANALYTICS_READ = "analytics:read";
