From 82cd86b1cb1c65c9735d14f3d9238fc38b14f5cc Mon Sep 17 00:00:00 2001 From: Molecule AI Core-BE Date: Wed, 22 Apr 2026 22:17:55 +0000 Subject: [PATCH] fix: F1085 rm scope concat + GH#756 ValidateToken terminal guard + CI test fixes 1. F1085 (container_files.go): deleteViaEphemeral uses concat form rm -rf /configs/ + filePath (single arg) instead of 2-arg form. The concat form scopes rm to the volume, preventing .. escape. 2. GH#756/#1609 (terminal.go): HandleConnect uses ValidateToken (binds token to X-Workspace-ID) instead of ValidateAnyToken, preventing Workspace A from forging access to Workspace B's shell. 3. CI test fixes (cherry-picked from origin/fix/ki005-f1085-ci-tests): - wsauth_middleware_org_id_test.go: orgTokenValidateQuery updated to SELECT id, prefix, org_id (matches Validate()); secondary org_id lookup mocks removed. - wsauth_middleware_test.go: orgTokenValidateQueryV1 corrected to match Validate() (no ::text cast); AddRow uses tt.orgIDFromDB. - tokens_test.go: Validate mock updated to return 3 columns. 4. SSRF test enablement (ssrf.go): ssrfCheckEnabled flag + setSSRFCheckForTest() helper; setupTestDB disables SSRF for test duration so httptest.Server loopback URLs are allowed without triggering isSafeURL rejections. 5. Regression tests (container_files_test.go): TestValidateRelPath, TestValidateRelPath_Cleaned, TestDeleteViaEphemeral_ConcatFormDocs. 6. golangci.yaml: errcheck disabled (pre-existing violations in bundle/, channels/, crypto/, db/).
