How to Fix CVE-2025-32380

To remediate this vulnerability, upgrade all affected Apollo router dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

apollo-router fixed: 1.61.2
Upgrade apollo-router to 1.61.2
apollo-router fixed: 2.1.1
Upgrade apollo-router to 2.1.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for apollo-router

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-32380, inspect your project dependencies for Apollo router:

inspect dependencies for apollo-router

Analyze the terminal output to locate any version of Apollo router in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.61.2), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-770: Allocation of Resources Without Limits or Throttling, where the product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated. In Apollo router, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

# Impact ## Summary A vulnerability in Apollo Router's usage of Apollo Compiler allowed queries with deeply nested and reused named fragments to be prohibitively expensive to validate. This could lead to excessive resource consumption and denial of service. ## Details Named fragments were being processed once per fragment spread in some cases during query validation, leading to exponential resource usage when deeply nested and reused fragments were involved. ## Fix/Mitigation Apollo Router's usage of Apollo Compiler has been updated so that validation logic processes each named fragment only once, preventing redundant traversal. # Patches This has been remediated in `apollo-router` versions 1.61.2 and 2.1.1. # Workarounds The only known workaround is "Safelisting with IDs only" per [Safelisting with Persisted Queries - Apollo GraphQL Docs](https://www.apollographql.com/docs/graphos/routing/security/persisted-queries#router-security-levels). The "Safelisting" security level is not sufficient, since that level allows freeform GraphQL queries to be sent to Apollo Router. # References [Query Planning Documentation](https://www.apollographql.com/docs/graphos/reference/federation/query-plans) ## Acknowledgements We appreciate the efforts of the security community in identifying and improving the performance and security of query validation mechanisms.
