Summary

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.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
