Prior to v4.15.0-beta5, two FastGPT file handlers authorize an unrelated resource and then sign or read an S3 object using a key taken directly from the request, without checking that the key belongs to the caller&#39;s team. Because S3 object keys are global within the bucket and carry the tenant id only as a path segment, an attacker can supply another team&#39;s key and obtain its file contents through the chat-file presign endpoint or dataset preview endpoint. This issue is fixed in version v4.15.0-beta5.</p> <p>FastGPT is an open source AI knowledge base platform.
