Closing — this is the right alert but the wrong fix for this repo.

next@12.3.7 is genuinely in range for GHSA-2xp9-vwfh-vxw4 (>= 10.0.0, < 15.5.24), but jumping 12 → 15 in one Dependabot PR is a migration, not a bump: Build and deploy already fails on this branch, and the app still depends on .babelrc (no SWC), experimental.esmExternals for Pure-ESM reef-knot, and the styled-components Babel transform.

Mitigations verified in this codebase for the AVIF image-optimizer RCE:

• images: { unoptimized: true } (next.config.mjs:81) — note the /_next/image route is still registered regardless (next-server.js:196), so this alone isn't a fix.
• No images.domains / images.remotePatterns configured, so /_next/image?url= accepts same-origin paths only — an attacker can't point the optimizer at their own AVIF.
• sharp is not installed; Next 12 falls back to the squoosh WASM path.

Alert dismissed as tolerable risk on that basis. The Next major upgrade should be tracked as its own piece of work.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
