CVE-2025-67819: Weaviate

Medium severity, CVSS 4.9. EPSS: 0.5% chance of exploitation in the next 30 days.

An issue was discovered in Weaviate OSS before 1.33.4. Due to a lack of validation of the fileName field in the transfer logic, an attacker who can call the GetFile method while a shard is in the "Pause file activity" state and the FileReplicationService is reachable can read arbitrary files accessible to the service process.
