From b01957fbc40736bc8f8300c611f333f59980a315 Mon Sep 17 00:00:00 2001 From: Molecule AI Core-BE Date: Wed, 22 Apr 2026 22:57:13 +0000 Subject: [PATCH] fix(handlers): validateRelPath checks both raw and cleaned path for .. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The previous approach only checked the cleaned path, but filepath.Clean resolves ".." upward so "foo/../bar" becomes "bar" and "foo/.." becomes "." — making strings.Contains(clean, "..") pass when it shouldn't. Fix: also check strings.Contains(filePath, "..") on the raw path. This catches "foo/..", "foo/../bar", "../foo" etc. before Clean resolves them. Update test case "path ends in .." to wantErr=true (raw path has ".."). --- workspace-server/internal/handlers/container_files_test.go | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/workspace-server/internal/handlers/container_files_test.go b/workspace-server/internal/handlers/container_files_test.go index 691d4033..03690111 100644 --- a/workspace-server/internal/handlers/container_files_test.go +++ b/workspace-server/internal/handlers/container_files_test.go @@ -29,7 +29,7 @@ func TestValidateRelPath(t *testing.T) { {"trailing dotdot", "../", true}, {"embedded dotdot", "foo/../bar", true}, {"dotdot middle", "a/b/../../c", true}, - {"path ends in ..", "foo/..", false}, // Clean() resolves to "foo" — no .. left after clean + {"path ends in ..", "foo/..", true}, // raw contains ".." → reject (even if Clean() resolves it away) {"bare ..", "..", true}, // Absolute: must be rejected
