CVE-2025-67819 Details
Description
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.
A path traversal vulnerability has been identified in Weaviate OSS versions prior to 1.33.4, specifically within the Shard Movement API. This vulnerability arises from inadequate validation of the fileName parameter in the transfer logic. An attacker who can invoke the GetFile method while a shard is in the 'Pause file activity' state, and with access to the FileReplicationService, can exploit this flaw to read arbitrary files accessible to the service process. The vulnerability requires that the Shard Movement API is enabled and that shards are paused, allowing for exploitation by manipulating the fileName parameter to traverse directories and access restricted files.
Users can update Weaviate to version 1.33.4 or later to address this vulnerability. If an immediate update is not possible, the Shard Movement API can be disabled by setting the 'REPLICA_MOVEMENT_ENABLED' flag to false.
