fix(deps): bump next to ^15.5.21 and override sharp to ^0.35.0 - #350
Merged
Conversation
Resolves all 9 open Dependabot alerts on the default branch: - next 15.5.20 -> 15.5.22 (alerts 3-10: SSRF in Server Actions and rewrites, cache confusion, Server Action DoS, SVG image DoS, server function endpoint disclosure; first patched in 15.5.21) - sharp 0.34.5 -> 0.35.3 via npm override (alert 2: libvips CVE-2026-33327/33328/35590/35591; first patched in 0.35.0). next 15.5.21 still pins sharp ^0.34.3, so an override is required until upstream bumps its optional dependency. Verified locally: npm ci, npm test (183 pass), npm run build. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Summary
Resolves all 9 open Dependabot alerts on the default branch (4 high, 5 moderate). All 9 map to two packages:
Reachability
"use server"appears nowhere) and no rewrites (only a/signinredirect), so the two SSRF alerts and the Server-Action DoS/payload alerts are not directly exploitable today — patched anyway sincenextis a runtime dependency and usage can change.next/image, so the SVG image-optimization DoS (Implement Google Tag Manager #5) and the sharp/libvips alerts (Update install steps #2) are plausibly reachable on the Netlify runtime.Why the sharp override
next15.5.21+ still pinssharp@^0.34.3as its optional dependency, so bumpingnextalone cannot pull in the patched sharp. An npmoverridesentry forces^0.35.0until upstream bumps its range. The existingpostcssoverride pattern is preserved.Verification
