🔒 Security Fix
This PR addresses Dependabot security alert #120 by upgrading
urllib3from version 2.5.0 to 2.6.2.Vulnerability Details
Impact
The urllib3 streaming API improperly handles highly compressed data. When streaming a compressed HTTP response, urllib3 could decompress a small amount of highly compressed data in a single operation, leading to:
Applications using urllib3's streaming methods (
stream(),read(),read1(),read_chunked(),readinto()) to handle compressed responses from untrusted sources were vulnerable.Fix
Upgraded urllib3 to version 2.6.2, which includes proper limits to prevent decompressing data that exceeds the requested amount.
