Summary

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.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
