📄 Description

Summary

Resolves literal URLs when fetch is invoked with an inline new Request(...) / Request(...) constructor or through an unchanged variable holding a Request instance, fixing #6359.

Fixes #6359

Problem and expected behavior

Prior to this fix, calling fetch(new Request("/api/chat", { method: "POST" })) or const req = new Request("/api/chat"); fetch(req); failed to extract the target URL "/api/chat". Instead, inspectEndpointCall treated any non-literal first argument as dynamic and emitted the full constructor expression as a partial endpoint (value: 'new Request("/api/chat", { method: "POST" })').

Expected behavior is to extract the literal URL string (value: "/api/chat", mechanism: "call:fetch") directly, matching the behavior of fetch("/api/chat", { method: "POST" }).

Change and scope

  • Added requestConstructorUrl helper in src/domain/javascript/javascriptStaticAnalysisCalls.ts that verifies the callee is an unmodified global Request reference and extracts stringValue(arguments[0]).
  • In inspectEndpointCall, resolve the target URL via stringValue(target) ?? requestConstructorUrl(target, bindings).
  • In urlObjectRequestTarget, resolve Request constructor initializers for stable variable bindings and aliases.
  • Added regression tests in src/domain/javascript/javascriptStaticAnalysis.partialEndpoints.test.ts.

Contract and boundary impact

  • Semantic owner and earliest changed stage: src/domain/javascript/javascriptStaticAnalysisCalls.ts
  • Contribution scope fit and linked maintainer decision: not applicable (bug fix within existing JavaScript static analysis boundary)
  • CLI and MCP/tool-catalog contract: none
  • Provider, bridge, target-format, or platform compatibility: none
  • Evidence, artifact, provenance, or reconstruction contract: none
  • Target selection, authority, upstream behavior, and cleanup details: none
  • Generated metadata impact: none

Expected effects:

  • Read existing files or captured data.
  • Launch or attach to a process.
  • Inject instrumentation or run scripts/code.
  • Change process memory, registers, files, or configuration.
  • Contact network services.
  • Recover protected code or work around protections.
  • Documentation or usability only; no target interaction.
  • Not sure yet; investigation or maintainer guidance needed.

Evidence and regression coverage

  • Tests added or updated: src/domain/javascript/javascriptStaticAnalysis.partialEndpoints.test.ts
  • Base reproduction: fetch(new Request("/api/chat", { method: "POST" })) failed on base revision by returning resolution: "partial", value: "new Request(\"/api/chat\", { method: \"POST\" })".
  • Remaining proof gaps: none

For evidence-bearing changes:

  • Observed, derived, and inferred claims remain distinguishable.
  • Artifact identity, source provenance, and failed attempts remain preserved.
  • Unsupported, incomplete, unavailable, or uncertain outcomes remain visible.

Validation performed

  • npm run test:local -- src/domain/javascript/javascriptStaticAnalysis.partialEndpoints.test.ts — 18 passed (18)
  • npm run test:local -- src/domain/javascript/javascriptStaticAnalysis.mapEndpoints.test.ts src/domain/javascript/javascriptStaticAnalysis.routeProperties.test.ts src/domain/javascript/javascriptStaticAnalysis.event_source.test.ts src/domain/javascript/javascriptStaticAnalysis.send_beacon.test.ts — 111 passed (111)
  • npm run check:fast — 2 tasks successful (typecheck + lint)

Compatibility, safety, and release

  • Breaking changes or migration steps: none
  • Real Hopper/Ghidra, browser, or OS coverage: not applicable
  • Package or release metadata impact: none
  • Security, privacy, process, or containment review: none
