Distillation

• 🟡 (11:34) User asked to continue.
• 🟡 (11:34) Assistant stated the manual redirect loop was implemented but its tests exposed a control-flow defect; it would correct that path before covering OAuth token-refresh redirects so refresh tokens cannot leave their scoped origin.
• 🟡 (11:34) Work-status checklist: 1. “Trace redirect and OAuth refresh authentication paths” completed (high priority); 2. “Fix redirect trust pinning and OAuth redirect handling” in progress (high); 3. “Add deterministic redirect security regressions” pending (high); 4. “Run focused and package validation” pending (high); 5. “Repeat independent final-diff reviews” pending (high); 6. “Review final diff and report outcome” pending (medium).
• 🟡 (11:34) Redirect/OAuth source search identified relevant tests including packages/cli/test/lib/sentry-client.test.ts trusted-307 redirect coverage at lines 119–164; packages/cli/test/lib/security/sntrys-claim-mismatch.test.ts cross-origin custom-header redirect refusal at lines 261–286; and packages/cli/test/lib/security/refresh-token-poison.test.ts refresh-token exfiltration regressions at lines 1–95.
• 🟡 (11:34) packages/cli/test/lib/sentry-client.test.ts test "follows a trusted 307 redirect without consuming a Request body" sends a POST Request with payload {"redirect":"preserve-body"} from https://us.sentry.io/api/0/__test_redirect_request_body__/ to same-origin destination https://us.sentry.io/api/0/__test_redirect_request_body__/redirected/; it expects both requests to retain the body and Authorization: Bearer test-token.
• 🟡 (11:34) packages/cli/test/lib/sentry-client.test.ts also covers: retrying a string POST body after a 503; retrying a Request POST body after a 502; retrying a ReadableStream body materialized once after a 500 with duplex: "half"; and retrying FormData without losing its auto-negotiated Content-Type: multipart/form-data; boundary=... header.
• 🔴 (11:35) User asserted: “Never forward headers across an unvalidated origin.” Redirect handling must validate the destination origin before forwarding/rebuilding headers.
• 🟡 (11:35) Working-tree modifications reported in .lore.md; packages/cli/plugins/sentry-cli/skills/sentry-cli/references/dashboard.md, event.md, explore.md, feedback.md, issue.md, log.md, replay.md, span.md, and trace.md; packages/cli/src/lib/constants.ts, packages/cli/src/lib/region.ts, and packages/cli/src/lib/sentry-client.ts; and packages/cli/test/lib/constants.test.ts, packages/cli/test/lib/security/sntrys-claim-mismatch.test.ts, and packages/cli/test/lib/sentry-client.test.ts.
• 🟡 (11:35) packages/cli/src/lib/sentry-client.ts diff introduces MAX_REDIRECTS = 20 (“Matches native fetch”), FetchWithTimeoutResult containing response: Response and headers: Headers, redirect recognition for statuses 301, 302, 303, 307, and 308, plus getRedirectUrl(response, request) which throws ApiError when Location is missing.
• 🟡 (11:35) packages/cli/src/lib/sentry-client.ts redirect flow clones an existing Request or obtains one via getInitialRedirectRequest(input, init), and includes a security check documented as “Never forward headers across an unvalidated origin.”
• 🟡 (11:36) packages/cli/test/lib/oauth.test.ts verifies resolveOAuthScopeString: no selection returns OAUTH_SCOPES.join(" "); { readOnly: true } returns only :read scopes in OAUTH_SCOPES order; explicit scopes override readOnly; explicit scopes lowercase and preserve first-seen order; duplicates are removed; blank entries are skipped; unknown scope throws ValidationError with field "scope"; and empty resolved scopes throw ValidationError.
• 🔴 (11:36) User asserted the readOnly OAuth scope selection never includes write or admin scopes.
• 🟡 (11:36) Property-based OAuth tests in packages/cli/test/lib/oauth.test.ts use fast-check constantFrom(...SENTRY_SCOPES), uniqueArray, and DEFAULT_NUM_RUNS; every nonempty unique SENTRY_SCOPES subset must round-trip to its lowercased, space-joined form, and every individual known scope must be accepted.
• 🟡 (11:36) Region-trust search found registerTrustedRegionUrls(urls) in packages/cli/src/lib/db/regions.ts line 64; setOrgRegion(orgSlug, regionUrl) at line 182 registers its region URL; setOrgRegions(entries) at line 204 registers entries.map((e) => e.regionUrl); and callers in packages/cli/src/lib/api/organizations.ts, packages/cli/src/lib/api/projects.ts, and packages/cli/src/lib/region.ts.
• 🟡 (11:36) packages/cli/test/lib/security/refresh-token-poison.test.ts documents the CVE defense: poisoning env.SENTRY_URL after boot previously could POST a refresh token to an attacker’s /oauth/token/; refreshAccessToken now calls assertRefreshHostTrusted() before building the request body and throws CliError on host mismatch.
• 🟡 (11:36) Refresh-token poisoning regression: after captureEnvTokenHost() snapshots the default SaaS host, setting process.env.SENTRY_URL = "https://evil.com" causes await refreshAccessToken("fake-refresh-token") to throw before any fetch; expected fetchCalls is [], and the error matches /does not match|sentry auth login --url/.
• 🟡 (11:36) Matching-scope refresh regression: setting SENTRY_HOST and SENTRY_URL to https://sentry.example.com, then capturing the environment-token host, permits refreshAccessToken("fake-refresh-token") through host validation; the mocked fetch is attempted exactly once at https://sentry.example.com/oauth/token/.
