Cross-request token reuse via cached request variables
Published Feb 20, 2025 · Updated Feb 20, 2025
Information exposure in GraphQL Mesh 0.96.5 through 0.96.8 allows remote authenticated users to reuse cached request variables. In getExecuteFn, transformedRequestCache keys an entire transformed request only by its DocumentNode, so later executions reuse the first request's variables and transformation context. Root-level or single-source transforms must be enabled, and a repeated operation can run with the first caller's token until LRU eviction.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
