[Claude] Bump urllib3 to 2.7.0 to address CVE-2026-44431#32
Merged
Conversation
urllib3 < 2.7.0 forwards sensitive headers (Authorization, Cookie, Proxy-Authorization) across origins on cross-origin redirects taken through the low-level ProxyManager.connection_from_url().urlopen(..., assert_same_host=False) path. urllib3 enters here only as a transitive dep of requests (Sphinx's docs toolchain), so the runtime exposure is limited, but the lockfile shouldn't pin a vulnerable version. https://claude.ai/code/session_01SKZysXPuSUj2WWNrNqPZuC
The test's robust_std_err callable was constructing its inner EmpiricalDistribution without an rng, so the nested SE drew from the unseeded global default RNG. t_interval seeds the inner dist itself only when fast_std_err is None, so a user-supplied one has to seed itself. With the seed in place the bounds are bit-identical across runs and comfortably inside the existing tolerances. https://claude.ai/code/session_01SKZysXPuSUj2WWNrNqPZuC
