PYSEC-2026-3547 AIOHTTP: WebSocket client accepts compressed frames without negotiated permessage-deflate

Summary The client accepts and decompresses frames with the RSV1 bit set even when the permessage-deflate extension was not negotiated. Impact A client may unexpectedly decompress WebSocket frames when explicitly opted out. This could lead to additional CPU/memory consumption, but is unlikely to ...

httplib2: httplib2: Denial of Service via unbounded decompression of HTTP response bodies

A flaw was found in httplib2, a Python HTTP client library. This vulnerability allows a malicious or compromised HTTP server to send a small compressed data payload that, when decompressed by httplib2, expands to an extremely large size in memory. This unbounded decompression can lead to a Denial...
