ETK-2026-4099Zero's internal tracking ID, independent of the CVE number.
waiting for further signalsZero needs more public information before it can validate it.description
The graphql Ruby gem can fail to enforce an application's configured query complexity limit when legacy complexity-cost calculation is in use. A client may submit a query whose processing cost exceeds the intended limit; exploitation requires the application to use the default :legacy calculation mode.
mitigation
Upgrade the graphql gem to version 2.6.15 or later.
fixed in 2.6.15
outcome
Contextual, not validated: no deterministic check could cover this one, and no technique passed our review.
