Summary by CodeRabbit

• New Features
  • Collector endpoints can now be configured, with separate settings available for the general API and remote reporter.
• Bug Fixes
  • Invalid or insecure collector URLs are reported before setup proceeds, and mismatched reporter and API settings trigger a warning.
  • Crash reports and observability requests now use the configured collector endpoint, falling back to the default when no override is set.

Walkthrough

Collector URLs can now be configured through environment variables, validated, and normalized. Observability requests resolve the configured URL at request time. Run setup validates both URLs, reports a remote-only configuration, and forwards the selected reporter URL.

Changes: Collector URL handling

Layer / File(s)	Summary
URL selection and requests bin/testObservability/helper/constants.js, bin/testObservability/helper/helper.js, bin/testObservability/crashReporter/index.js, test/unit/bin/testObservability/collectorUrl.js	URL helpers validate and normalize primary and remote collector URLs. Observability requests and crash reports use the selected URL. Unit tests cover overrides, defaults, and request-time validation errors.
Run setup and URL forwarding bin/commands/runs.js, bin/helpers/utils.js, test/unit/bin/helpers/utils.js	Run setup validates both URLs and warns when only the remote URL is set. System environment setup forwards the selected remote reporter URL. Tests cover forwarding, warnings, and URL validation.

Merge Risk: Low · up to 8513d

Collector URL overrides now work with validation and forwarding. Two hardening concerns remain: POST bodies could be replayed over plain HTTP if the collector redirects, and a collector URL containing a path token could appear in debug output. Both are narrow and need unusual conditions, so they are worth addressing or explicitly accepting, but they should not block the feature.

Security architecture risk: Moderate · up to 8513d

The change preserves a secure default and rejects several unsafe URL forms. However, collector paths that contain secrets can reach debug output, and initial HTTPS validation does not constrain redirect destinations. Exposure depends on the configured run, enabled diagnostics, and collector behavior; broader account impact depends on the credentials involved.

Retained concerns

• Medium · security · observed: The newly automatic collector forwarding preserves URL paths and feeds the complete value into the existing system-environment debug message. A secret carried in an accepted collector path is therefore exposed to console-log readers when CLI debug logging is enabled. Rejecting userinfo and hiding paths in the new warning do not protect this separate logging path.
• Medium · security · inferred: HTTPS validation covers only the selected initial collector URL. Both authenticated request sinks delegate redirects to Axios without an application-level redirect-hop policy. This policy gap predates the PR, but newly configurable collectors expand the destinations whose redirect behavior must be trusted. The retained disclosure finding remains relevant; exact forwarding of bodies or authentication across particular redirect hops is unresolved.

Security review details

Security Blast Radius

• inferred — The destination-selection exposure begins with an affected CLI process and its forwarded remote runs. Traffic includes build JWTs and account access-key authentication. If account credentials are disclosed, impact may extend to assets accessible to that account; the available source does not establish those privileges or justify a fleet-wide or cross-tenant scope.

Security Findings and Attack Paths

• observed — The retained logging finding has a complete source trace: an accepted collector path survives normalization, automatic forwarding serializes it into system_env_vars, and the full array reaches the console logger. Disclosure requires a sensitive path, enabled CLI debug logging and access to its output. Logging arbitrary forwarded variables already existed; automatic inclusion of the collector URL is new.
• inferred — The retained redirect finding concerns sensitive traffic leaving the validated initial destination through collector-controlled redirects. Initial destination control requires environment-setting authority, while a redirect path requires influence over the selected endpoint's response. Application-level hop checks are absent, but actual body, credential and downgrade behavior remains dependent on uninspected transport implementation.

Trust Boundaries and Controls

• observed — The environment setter now selects the initial collector owner for authenticated requests. The validator constrains URL form but does not restrict HTTPS host ownership. The fixed HTTPS default, rejection of embedded credentials and preflight validation are meaningful controls; none establishes equivalence between separately configured collector environments.

Hardening Proposals

• proposed — Preserve the complete collector value for transport while redacting it from diagnostic environment dumps. Apply the same disclosure policy to normal warnings, debug output and request-error reporting.
• proposed — Define an explicit redirect policy for both request sinks: disable redirects where unnecessary, or validate every hop's scheme and permitted destination while accounting for body and authentication handling in the resolved HTTP client.
• proposed — Document and validate the identity relationship between local and remote collector endpoints. Consider binding validated destinations to the run lifecycle so later sends and cleanup cannot unintentionally select a different environment.

Redact the collector URL before debug logging.

remoteReporterApiUrl() is forwarded unchanged, then line 652 logs the complete system_env_vars array. With --cli-debug, a token in the URL path is exposed. Redact only the logged value.

Redact the URL only in the debug representation

This debug line predates the PR. It has logged the whole system_env_vars array since f0e8992 (Apr 2022), and that array already carries every env var the user forwards, which is where the real secrets are. This change adds one collector URL to it.

Redacting it properly means covering every forwarded value, not just this one key, so raising it separately rather than half-fixing it here.

[coderabbitai]

@manish-bothra Understood. A separate fix should cover all forwarded values in the system_env_vars debug output, while leaving the actual forwarded values unchanged. Redacting only the collector URL would leave the broader exposure in place.

The collector URL can still expose a path token through this log, so the concern remains valid but deferred, not fixed.

Would you like me to open a follow-up GitHub issue for comprehensive redaction?

Sensitive Data Exposure

Reachability: External
Exploitability: Difficult
CWE: CWE-319 — Cleartext Transmission of Sensitive Information

View Security blast radius

Keep observability POST bodies on HTTPS across redirects.

If the configured HTTPS collector sends a 307 redirect to an http:// URL, Axios follows it by default and resends the POST body over plaintext HTTP. The HTTPS check in constants.js validates only the initial URL, not redirect targets. Both POST sites are affected: the axios(options) call in nodeRequest in bin/testObservability/helper/helper.js, and the crash-report analytics upload at bin/testObservability/crashReporter/index.js:151. Neither site sets maxRedirects or beforeRedirect.

A 307 response must come from the collector itself, because it is sent inside TLS. This risk therefore applies when the collector is misconfigured or compromised. Confirm the redirect behavior against the Axios and follow-redirects versions in package-lock.json. Disabling redirects on both requests closes the downgrade path. Legitimate collector redirects will then fail, so confirm that no supported deployment relies on them.

Disable redirect following on both POST requests

[manish-bothra]

Mechanism confirmed: follow-redirects 1.16.0 drops confidential headers on an https to http redirect but still follows it, so the body would go out in cleartext.

It is pre-existing though. nodeRequest used axios the same way before this PR, which changed only where the base URL comes from, not the request options. The 307 would also have to come from the collector itself, inside TLS.

Raising it separately rather than adding commits to this PR.

[coderabbitai]

@manish-bothra Agreed. The diff changes collector URL selection, not Axios redirect handling. I should have distinguished this pre-existing risk from a regression introduced by this PR.

A separate follow-up is reasonable. The security finding remains valid but deferred, so this thread stays open rather than being marked fixed.

Would you like me to open a GitHub issue covering both request sites, redirect-downgrade tests, and collector redirect compatibility?
