CVE-2025-64530: Apollo Federation is an architecture for declaratively composing APIs into a unified graph.

Apollo Federation is an architecture for declaratively composing APIs into a unified graph.

Apollo Federation is an architecture for declaratively composing APIs into a unified graph. A vulnerability in versions of Apollo Federation's composition logic prior to 2.9.5, 2.10.4, 2.11.5, and 2.12.1 allowed some queries to Apollo Router to improperly bypass access controls on types/fields. Apollo Federation incorrectly allowed user-defined access control directives on interface types/fields, which could be bypassed by instead querying the implementing object types/fields in Apollo Router via inline fragments, for example. A fix to versions 2.9.5, 2.10.4, 2.11.5, and 2.12.1 of composition logic in Federation now disallows interfaces types and fields to contain user-defined access control directives. Some workarounds are available. Users of Apollo Rover with an unpatched composition version or are using the Apollo Studio build pipeline with Federation version 2.8 or below should manually copy the access control requirements on interface types/fields to each implementing object type/field where appropriate. Do not remove those access control requirements from the interface types/fields, as unpatched Apollo Composition will not automatically generate them in the supergraph schema.

What it means for a small business

If your business uses federation, install the vendor's update. If you're not sure whether you use it, ask whoever manages your computers.

How likely is an attack? The Exploit Prediction Scoring System, run by FIRST (the global association of security response teams), puts the odds of this one being exploited in the next 30 days at 0.41%, higher than 35% of CVEs. That’s low, but low isn’t zero, and the odds jump the day someone publishes an exploit. Scored October 29, 2026, updated daily.

Website check: reads what your site runs from the outside (WordPress version, plugins it can see, old server software) and matches it against this database.
Server check: what your web server says about itself, and whether that version has known flaws.
