# Patch Next advisory brief: CVE-2026-41843

Advisory: Spring Framework Path Traversal via Versioned Static Resources in Spring MVC and WebFlux
IDs: CVE-2026-41843, GHSA-72pg-x5f8-j25j
Record: https://patchnext.com/advisories/cve-2026-41843 (revision 1, source checked 26 Oct 2026, 16:54 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: org.springframework:spring-webmvc 7.0.8, 6.2.19; org.springframework:spring-webflux 7.0.8, 6.2.19. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.springframework:spring-webmvc: affected >= 7.0.0, <= 7.0.7; >= 6.2.0, <= 6.2.18; >= 6.1.0, <= 6.1.21; <= 5.3.39; fixed in 7.0.8, 6.2.19
- Maven org.springframework:spring-webflux: affected >= 7.0.0, <= 7.0.7; >= 6.2.0, <= 6.2.18; >= 6.1.0, <= 6.1.21; <= 5.3.39; fixed in 7.0.8, 6.2.19

## Suggested inspection (read-only)
- Maven org.springframework:spring-webmvc: check the installed version with your package manager.
- Maven org.springframework:spring-webflux: 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:spring-webmvc, org.springframework:spring-webflux.
- 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.

## Sources
