next is vulnerable to Information Disclosure
63
Medium Risk
This Affects:
nextTL;DR
Webpack builds of next drop the dynamicParams export when they load metadata image routes such as opengraph-image and twitter-image. A request for a dynamic segment that generateStaticParams() left out still runs that image route. The response can expose content the route was configured not to generate. The fix re-exports dynamicParams so the segment option is applied.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you build metadata image routes with webpack while dynamicParams is false.
Background info
next is vulnerable to Information Disclosure in versions 16.0.0 - 16.3.7.
