The vulnerability (CVE-2025-53007) is a ZipSlip path traversal in the backup restoration function. An attacker with database write access can craft an object entry name containing absolute paths (e.g., /etc/passwd) or directory traversal sequences (../../../). During the restoration of a malicious backup archive, the system improperly validates and sanitizes these entry names. This allows the attacker to break out of the intended restoration root directory. The vulnerable extraction logic writes files to arbitrary filesystem locations accessible by the Weaviate process. This can lead to creation, overwriting, or corruption of critical system or application files, enabling potential privilege escalation, denial of service, or remote code execution depending on the overwritten file’s nature and context.
DailyCVE Form:
Platform: Weaviate OSS
Version: <1.33.4
Vulnerability : Path Traversal
Severity: High
Date: 2025-12-12
Prediction: Patch released.
What Undercode Say:
Analytics:
find / -name weaviate -type f 2>/dev/null weaviate --version strings weaviate_binary | grep -i backup
How Exploit:
1. Attacker inserts malicious object.
2. Triggers backup creation.
3. Admin restores poisoned backup.
4. Files written outside root.
Protection from this CVE
Update to patched versions: 1.30.20, 1.31.19, 1.32.16, or 1.33.4. Implement strict network controls for database access. Restrict Weaviate process filesystem permissions. Audit backup files before restoration.
Impact:
Arbitrary file write. Potential denial-of-service. Possible privilege escalation. System compromise.
