Semgrep OSS and Bandit B310 Medium alerts on main flagged dynamic urllib use in CodeQL identity and Strix evidence helpers. Fail closed unless the URL is https://api.github.com so file:// and arbitrary hosts cannot reach urlopen. Co-authored-by: Cursor <cursoragent@cursor.com>

validate every redirect target with _assert_github_https_api_url before issuing

Converted back to Draft because exact head Keep this sibling open because it owns valid focused regressions for both URL-opening helpers. Repair by failing closed on redirects or validating every redirect target before dispatch and proving credentials cannot cross origin; add a deterministic cross-origin redirect RED/GREEN. If #2272 becomes the consolidated successor, explicitly inherit these focused regressions plus the redirect fix before closing/superseding #2269. |

Current-head security repair review: the CodeQL GHAS helper now has a dedicated _GitHubApiRedirectHandler that revalidates every redirect target against the admitted https://api.github.com origin before urllib dispatches the redirected request. This is the causal successor to RED 225260a8f949da525da5ff2190e3b413f41f88c0; same-origin redirects remain allowed, cross-origin targets raise ConfigurationIdentityError before bearer forwarding. Hosted exact-head checks are newly queued and are not GREEN evidence yet.
Remaining lane work is explicit rather than transferred: (1) strix_evidence_binding.default_github_opener still uses the default redirect path and needs the same credential-egress contract in its own source/test delta; (2) existing CodeQL helper tests that monkeypatch urllib.request.urlopen must be verified against the new dedicated opener on this exact head rather than assuming predecessor focused-test results still apply; (3) #2272 is a sibling and may only supersede this lane after inheriting both helpers' complete source + regression delta.

Current-head test-contract finding: the Strix production repair now dispatches through _GITHUB_API_OPENER.open(...), but tests/test_strix_evidence_binding.py still monkeypatches binding.urlopen in test_default_github_opener_error_paths and test_default_github_opener_success. Those patches no longer intercept the transport, so the focused tests can reach the real GitHub API instead of the intended fake response and can fail for the wrong reason. This is not a reason to revert redirect containment. Repair the tests to patch the actual dedicated opener seam (or introduce one explicit package-owned injectable transport seam without weakening the redirect invariant), and keep the cross-origin/same-origin redirect regressions. Fresh exact-head hosted evidence is required after that source/test repair; the currently queued generation must not be treated as prospective GREEN.

Replace retired urllib urlopen monkeypatches with direct CodeQL and Strix dedicated-opener patches. Remove the PR-specific global conftest bridge so both security helpers exercise the same explicit transport boundary without live network access.

Exact-current-head security review for 834d285f90241b4741247408001fd7534ce5a3b0 (tree 7673aad69f78d9876b85995ca9c17d4424f0e5c1).
The per-hop redirect containment remains intact for both CodeQL and Strix. Revalidation found and repaired a separate test-fixture defect: predecessor 4dcd25c9… left CodeQL tests on the retired generic urlopen seam, producing three deterministic failures and live-network attempts. Current head directly patches each package-owned dedicated opener and deletes the Strix-only global conftest bridge.
