Summary

Adds ownership verification to the delete handlers for env vars, labels, volumes, and ports. Previously, an authenticated user could delete any resource by ID regardless of which app ID was in the URL path (IDOR vulnerability).

Changes

  • internal/handlers/app.go: Added resource.AppID != appID check to HandleEnvVarDelete, HandleLabelDelete, HandleVolumeDelete, and HandlePortDelete
  • internal/handlers/handlers_test.go: Added 4 IDOR tests that create two apps, attach a resource to app1, then attempt deletion via app2 URL path

Fix

One-line change per handler — add || resource.AppID != appID to the existing nil/error check:

// Before:
if findErr != nil || envVar == nil {
// After:
if findErr != nil || envVar == nil || envVar.AppID != appID {

Closes #19

## Summary Adds ownership verification to the delete handlers for env vars, labels, volumes, and ports. Previously, an authenticated user could delete any resource by ID regardless of which app ID was in the URL path (IDOR vulnerability). ## Changes - `internal/handlers/app.go`: Added `resource.AppID != appID` check to `HandleEnvVarDelete`, `HandleLabelDelete`, `HandleVolumeDelete`, and `HandlePortDelete` - `internal/handlers/handlers_test.go`: Added 4 IDOR tests that create two apps, attach a resource to app1, then attempt deletion via app2 URL path ## Fix One-line change per handler — add `|| resource.AppID != appID` to the existing nil/error check: ```go // Before: if findErr != nil || envVar == nil { // After: if findErr != nil || envVar == nil || envVar.AppID != appID { ``` Closes #19

Tests demonstrate that env vars, labels, volumes, and ports can be
deleted via another app's URL path without ownership checks.

All 4 tests fail, confirming the vulnerability described in #19.
Verify that the resource's AppID matches the URL path app ID before
allowing deletion. Without this check, any authenticated user could
delete resources belonging to any app by providing the target resource's
ID in the URL regardless of the app ID in the path (IDOR vulnerability).

Closes #19

Code Review (detailed)

Reviewer: clawbot (automated review)

Summary

This PR fixes an IDOR (Insecure Direct Object Reference) vulnerability in the four resource deletion handlers: env vars, labels, volumes, and ports.

Fix Analysis (app.go)

  • Correct approach — each handler now verifies resource.AppID != appID before allowing deletion
  • Minimal change — 4 lines changed, one per handler, appended to existing guard clause
  • Consistent pattern — same fix applied uniformly to all four handlers
  • Matches existing convention — the deployment log handlers (HandleDeploymentLogsAPI, HandleDeploymentLogDownload) already use this exact pattern: deployment.AppID != appID

Test Analysis (handlers_test.go)

  • Proper IDOR test pattern — creates two apps, attaches resource to app1, attempts delete via app2 URL
  • Two-phase assertion — checks both HTTP 404 response AND verifies resource still exists in DB
  • All four resource types covered — env var, label, volume, port
  • Parallel-safe — each test uses its own DB instance

Non-blocking suggestions

  • Consider adding positive tests (deleting via correct app ID succeeds)
  • golangci-lint not available locally; CI should confirm

Verdict

LGTM — Ship it.

Merge conflicts resolved. Rebased on latest main and fixed the test file conflicts — both the existing TestHandleWebhookRejectsOversizedBody test and the new IDOR ownership verification tests are preserved and passing. All 5 relevant tests pass. Ready for re-review.
