Apollo Router Core is a configurable Rust graph router written to run a federated supergraph using Apollo Federation 2. Versions 1.61.12-rc.0 and below and 2.8.1-rc.0 allow unauthorized access to protected data through schema elements with access control directives (@authenticated, @requiresScopes, and @policy) that were renamed via @link imports. Router did not enforce renamed access control directives on schema elements (e.g. fields and types), allowing queries to bypass those element-level access controls. This issue is fixed in versions 1.61.12 and 2.8.1.

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.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
