Note

Medium Risk
A Next 14→15 major bump can break snippet build/test behavior even in a private example app; eslint-config-next remains on 14.x, which may cause lint/config drift.

Overview
Bumps the next dependency in packages/sdks/snippets/react-sdk-next-14-app from 14.2.25 to 15.5.21 (major version upgrade). No other manifest or source files change in this PR.

The new release line includes multiple security fixes (Server Actions DoS/SSRF, middleware bypass, cache confusion, image optimization, and related advisories noted in the release notes).

Wrong Next major for Next 14 package

High Severity

Dependabot major-bumped next from 14.2.25 to 15.5.21 in @snippet/react-sdk-next-14-app, a package intentionally pinned to Next.js 14. A separate Next 15 e2e package already exists. This removes Next 14 snippet coverage, leaves react/eslint-config-next on v14-era versions, and conflicts with App Router pages that still use sync params/searchParams.
