Summary

CVE-2025-67818 affects Weaviate OSS before 1.33.4. An attacker who can insert data into the database can craft an entry name using an absolute path (such as /etc/...) or parent directory traversal (../../..), causing a backup restore to escape the restore root. This can create or overwrite files in arbitrary locations within the application's privilege scope. The weakness is classified as CWE-22.

Mitigation

Fixed in Weaviate OSS 1.33.4 or later. The vendor advisory is at https://weaviate.io/blog/weaviate-security-release-november-2025.
