CVE-2026-2818: Zip Slip Path Traversal in Snapshot Archive Extraction (Windows-Specific)

A zip-slip path traversal vulnerability in Spring Data Geode's import snapshot functionality allows attackers to write files outside the intended extraction directory. This vulnerability appears to be susceptible on Windows OS only.

Security readout for executives and security teams

Plain-English summary

This flaw can let a crafted snapshot archive place files outside the intended folder during import. The source bundle says susceptibility appears Windows-specific. If affected Spring Data Geode or GemFire versions process untrusted snapshots, the main business risk is unauthorized file writes that could alter application behavior or data integrity.

Executive priority

Treat as high priority for Windows-hosted services using the named legacy Spring Data components and snapshot import. Urgency drops if the affected versions are absent or snapshot import is not used.

Technical view

CVE-2026-2818 is a zip-slip path traversal in Spring Data Geode import snapshot handling, mapped to CWE-22 and CWE-23. Listed affected packages are org.springframework.data:spring-data-geode 2.0.0.RELEASE and org.springframework.data:spring-data-gemfire 1.7.0.RELEASE. CVSS 3.1 is 8.2, with network attack vector, no privileges, user interaction required, changed scope, low confidentiality impact, and high integrity impact.

Likely exposure

Exposure is most likely where Windows systems run the listed Spring Data Geode or GemFire versions and import snapshot archives. Environments that never use snapshot import, do not run affected versions, or do not run on Windows are less likely exposed based on the provided evidence.

Exploitation context

The bundle does not cite active exploitation, and KEV is false. Exploitation requires a crafted archive to be imported, so practical risk depends on who can provide snapshots and whether operators process untrusted archives.

Researcher notes

Evidence identifies the vulnerable function, affected package versions, Windows-specific susceptibility, CWE classes, and CVSS vector. The provided bundle does not name a fixed version, patch commit, exploit sample, or confirmed exploitation, so remediation should be tied to vendor guidance.

Mitigation direction

  • Inventory Spring Data Geode and GemFire dependencies for the listed affected versions.
  • Prioritize review of Windows deployments and snapshot import workflows.
  • Do not import snapshot archives from untrusted or unauthenticated sources.
  • Restrict snapshot import privileges to trusted administrators only.
  • Check HeroDevs, Red Hat, and project guidance for fixed versions or vendor mitigations.

Validation and detection

  • Search dependency manifests for org.springframework.data:spring-data-geode 2.0.0.RELEASE.
  • Search dependency manifests for org.springframework.data:spring-data-gemfire 1.7.0.RELEASE.
  • Confirm whether affected applications run on Windows hosts.
  • Identify jobs, admin tasks, or APIs that invoke snapshot import.
  • Review whether snapshot archives can originate from external or lower-trust users.
  • Check vendor advisories and VEX data for current product status.
