• CVE-2023-50730: 0.83% estimated exploitation activity in the next 30 days; percentile 57.53 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Impact Prior to this fix, the GraphQL query parsing was vulnerable to StackOverflowErrors. The possibility of small queries resulting in stack overflow is a potential denial of service vulnerability. This potentially affects all applications using Grackle which have untrusted users. [!CAUTION] No specific knowledge of an application's GraphQL schema would be required to construct a pathological query. Patches The stack overflow issues have been resolved in the v0.18.0 release of Grackle. Workarounds Users could interpose a sanitizing layer in between untrusted input and Grackle query processing.

Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: org.typelevel:grackle-core_3 0.18.0; org.typelevel:grackle-core_native0.4_3 0.18.0; org.typelevel:grackle-core_native0.4_2.13 0.18.0; org.typelevel:grackle-core_sjs1_3 0.18.0; org.typelevel:grackle-core_sjs1_2.13 0.18.0; org.typelevel:grackle-core_2.13 0.18.0. A vendor fix does not mean a deployment is fixed.

## Suggested inspection (read-only)
- Maven org.typelevel:grackle-core_3: check the installed version with your package manager.
- Maven org.typelevel:grackle-core_native0.4_3: check the installed version with your package manager.
- Maven edu.gemini:gsp-graphql-core_3: check the installed version with your package manager.
- Maven org.typelevel:grackle-core_native0.4_2.13: check the installed version with your package manager.
- Maven edu.gemini:gsp-graphql-core_sjs1_3: check the installed version with your package manager.
- Maven edu.gemini:gsp-graphql-core_native0.4_2.13: check the installed version with your package manager.
- Maven org.typelevel:grackle-core_sjs1_3: check the installed version with your package manager.
- Maven edu.gemini:gsp-graphql-core_2.13: check the installed version with your package manager.
- Maven edu.gemini:gsp-graphql-core_sjs1_2.13: check the installed version with your package manager.
- Maven edu.gemini:gsp-graphql-core_native0.4_3: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.typelevel:grackle-core_3, org.typelevel:grackle-core_native0.4_3, edu.gemini:gsp-graphql-core_3, org.typelevel:grackle-core_native0.4_2.13, edu.gemini:gsp-graphql-core_sjs1_3, edu.gemini:gsp-graphql-core_native0.4_2.13, org.typelevel:grackle-core_sjs1_3, edu.gemini:gsp-graphql-core_2.13, edu.gemini:gsp-graphql-core_sjs1_2.13, edu.gemini:gsp-graphql-core_native0.4_3, org.typelevel:grackle-core_sjs1_2.13, org.typelevel:grackle-core_2.13.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
