Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Apollo Server is an open-source, spec-compliant GraphQL server that's compatible with any GraphQL client,
 including Apollo Client. In versions from 2.0.0 to 3.13.0, 4.2.0 to before 4.13.0, and 5.0.0 to before
 5.4.0, the default configuration of startStandaloneServer from @apollo/server/standalone is vulnerable to

 encodings. This issue does not affect users that use @apollo/server as a dependency for integration
 packages, like @as-integrations/express5 or @as-integrations/next, only direct usage of
 startStandaloneServer. (CVE-2026-23897)
