urllib3: urllib3 vulnerable to decompression-bomb safeguard bypass when following HTTP redirects (streaming API)
A flaw was found in urllib3. When processing HTTP redirect responses during data streaming, the library automatically reads and decompresses the full response body without enforcing configured size limits. A malicious server can exploit this by serving an excessively compressed response, bypassin...
