From 3336e5af0041b4f201cee5a59b57e08d15c75445 Mon Sep 17 00:00:00 2001 From: Kiell Tampubolon <113831023+eltypical@users.noreply.github.com> Date: Wed, 29 Jul 2026 15:00:05 +0800 Subject: [PATCH 1/7] fix(space): close IDOR in comment list/create and broken queryset kwargs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit VULN-01 — Cross-project comment list IDOR (AllowAny endpoint) The IssueCommentPublicViewSet.get_queryset() filtered only by workspace_id and the URL-supplied issue_id, with no project_id guard. Any unauthenticated caller who knew a private issue UUID could read all its EXTERNAL comments through any public board in the workspace. Fix: add .filter(project_id=project_deploy_board.project_id). VULN-02 — Cross-project comment injection IssueCommentPublicViewSet.create() accepted the URL issue_id without confirming it belonged to the board's project. A caller could POST a comment referencing an issue from a different private project, creating a semantically inconsistent row (comment.project_id ≠ issue.project_id) and contaminating private project data. Fix: validate issue existence in project_id before serializer.save(). VULN-04 — IssueVotePublicViewSet.get_queryset() wrong lookup kwarg The queryset used workspace__slug=self.kwargs.get("anchor") but "anchor" is an opaque token, never a workspace slug. This caused DeployBoard.DoesNotExist on every list request, silently returning an empty queryset and making vote listing permanently broken. Fix: use anchor=self.kwargs.get("anchor") to match the URL pattern. BONUS — IssueReactionPublicViewSet.get_queryset() wrong lookup kwargs Same class of bug: the queryset looked up the DeployBoard via workspace__slug=self.kwargs.get("slug") and project_id=self.kwargs.get("project_id"), but the URL pattern /anchor//issues//reactions/ provides neither "slug" nor "project_id" kwargs. Both resolved to None, causing DeployBoard.DoesNotExist on every list request. Fix: use anchor=self.kwargs.get("anchor") and derive project/workspace from the resolved board object.

IssueVotePublicViewSet.create() and IssueReactionPublicViewSet.create() both received _issue_belongs_to_board() ownership guards in the Phase-3 hardening commit, but no regression tests were added for those paths. A future refactor could silently remove the guards with no test failure. 2. test_reaction_list_returns_results_when_enabled contained a vacuous assertion (`!= uuid4()`) that always evaluates True regardless of actual code behaviour, providing no security value. Changes: - Add TestIssueVoteCreateProjectIsolation (2 tests: 404 on foreign issue, 201 on own issue) - Add TestIssueReactionCreateProjectIsolation (2 tests: 404 on foreign issue, 201 on own issue) - Fix vacuous uuid4() assertion in TestIssueReactionGetQuerysetKwarg Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- apps/api/tests/test_space_issue_security.py | 208 ++++++++++++++++++-- 1 file changed, 190 insertions(+), 18 deletions(-) diff --git a/apps/api/tests/test_space_issue_security.py b/apps/api/tests/test_space_issue_security.py index b6aba22c3f7..b8a3cbb7b80 100644 --- a/apps/api/tests/test_space_issue_security.py +++ b/apps/api/tests/test_space_issue_security.py @@ -7,6 +7,7 @@ VULN-02 Cross-project comment injection (IsAuthenticated endpoint) VULN-04 IssueVotePublicViewSet.get_queryset() used wrong kwarg BONUS IssueReactionPublicViewSet.get_queryset() used wrong kwargs +Phase-3 Cross-project vote/reaction injection in create() (adversarial review finding) Each test class documents: - the original exploit scenario (should now return 404 or empty) @@ -49,16 +50,6 @@ class TestIssueCommentGetQuerysetProjectIsolation: between the workspace_id filter and the issue_id filter.
