Medium (6.1) in apollographql apollo client. EPSS 0.4% chance of exploitation in the next 30 days. Fixed in @apollo/experimental-nextjs-app-support 0.7.0.
apollo-client-nextjs is the Apollo Client support for the Next.js App Router. The @apollo/experimental-apollo-client-nextjs NPM package is vulnerable to a cross-site scripting vulnerability. To exploit this vulnerability, an attacker would need to either inject malicious input (e.g. by redirecting a user to a specifically-crafted link) or arrange to have malicious input be returned by a GraphQL server (e.g. by persisting it in a database). To fix this issue, please update to version 0.7.0 or later.
