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. +## 2026-10-11 - Missing Authorization on Admin Endpoints +**Vulnerability:** The `/api/v1/admin/convert/jobs` and associated endpoints did not implement `TenantAccessService` authorization checks, exposing internal conversion jobs. +**Learning:** Even internal or admin APIs require explicit tenant permission checks (e.g. `admin:operate`) via the central authorization layer. +**Prevention:** All administrative and debugging endpoints must be secured using `TenantAccessService.require(headers, permission)` before processing requests. diff --git a/src/main/java/com/clearfolio/viewer/auth/TenantPermissions.java b/src/main/java/com/clearfolio/viewer/auth/TenantPermissions.java index 4f9c6a685..8ac19a34f 100644 --- a/src/main/java/com/clearfolio/viewer/auth/TenantPermissions.java +++ b/src/main/java/com/clearfolio/viewer/auth/TenantPermissions.java @@ -5,6 +5,11 @@ */ public final class TenantPermissions { + /** + * Permission required to operate on administrative endpoints. + */ + public static final String ADMIN_OPERATE = "admin:operate";
