# Patch Next advisory brief: CVE-2026-40974

Advisory: Spring Boot's Cassandra SSL auto-configuration disables TLS hostname verification
IDs: CVE-2026-40974, GHSA-mqvw-jfmh-93qq
Record: https://patchnext.com/advisories/cve-2026-40974 (revision 1, source checked 26 Oct 2026, 16:45 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.0)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: org.springframework.boot:spring-boot-cassandra 4.0.6, 3.5.14. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.springframework.boot:spring-boot-cassandra: affected >= 4.0.0, < 4.0.6; >= 3.5.0, < 3.5.14; >= 3.4.0, <= 3.4.15; >= 3.3.0, <= 3.3.18; <= 2.7.32; fixed in 4.0.6, 3.5.14

## Suggested inspection (read-only)
- Maven org.springframework.boot:spring-boot-cassandra: 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.springframework.boot:spring-boot-cassandra.
- 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.
