CVE-2026-54698 hasura CVE debrief

Who should care

Users of Hasura's GraphQL or REST APIs, affected operators, platforms, and security teams should be aware of this vulnerability and take steps to defend against it. This includes reviewing and adjusting where clauses on table computed fields, monitoring for suspicious activity, and prioritizing updates and compensating controls.

Technical summary

Prior to 2.49.2 and 2.45.5, a user can use a where clause on a table computed field (returning SETOF some_table) to infer row values that ought to be filtered for their role based on some_table's row-level permissions. While such rows cannot be returned directly, like predicates on strings for instance allow values to be brute forced efficiently with the where clause as an oracle. The vulnerability allows potential brute-force attacks on string predicates, which can be mitigated by updating to the fixed versions.

Defensive priority

Medium

Recommended defensive actions

• Update to version 2.49.2 or 2.45.5 or later
• Review and adjust where clauses on table computed fields
• Monitor for suspicious activity
• Review compensating controls for exposed systems
• Check relevant monitoring, detection, and logs for exposed assets
• Track exceptions and retest remediated assets
• Confirm whether affected product deployments exist in managed environments

Evidence notes

The CVE record was published on 2026-07-07T22:16:53.500Z and has not been modified since then. The NVD entry is currently 6.0 MEDIUM. The Hasura vulnerability allows users to infer row values that should be filtered based on role-level permissions. Evidence is limited, and defenders should verify the affected scope and vendor guidance. Limited source detail suggests verifying affected product deployments exist in managed environments and reviewing compensating controls for exposed systems.
