The affected range collapses two disjoint intervals into their union. The source advisory at /repos/remix-run/react-router/security-advisories lists two products: >= 7.12.0, < 7.18.2 patched at 7.18.2, and >= 8.0.0, < 8.3.0 patched at 8.3.0. Its updated_at equals published_at (2026-07-22), so this was its shape at publication.
The v7 fix is PR #15353, "Harden RSC CSRF codepaths (backport of #15311)", whose commit message states "Backports the fix for GHSA-qwww-vcr4-c8h2 to v7". Merged 2026-07-28 20:52Z, released in 7.18.2 at 21:53Z. The current record's references cite only v8 material.
As it stands, npm audit reports 7.18.2 as vulnerable and npm audit fix --force proposes downgrading to 7.11.0, which moves users away from the fix.
