PYSEC-2026-1996 Decompression-bomb safeguards bypassed when following HTTP redirects (streaming API)

Impact urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. urllib3 can perform decoding or decompression based on the HTTP Content-Encoding header e.g., gzip,...

urllib3 allows an unbounded number of links in the decompression chain

Impacturllib3 supports chained HTTP encoding algorithms for response content according to RFC 9110 e.g., Content-Encoding: gzip, zstd.However, the number of links in the decompression chain was unbounded allowing a malicious server to insert a virtually unlimited number of compression steps leadi...

httpd: incomplete fix for CVE-2023-38709

A flaw was found in httpd. The response headers are not sanitized before an HTTP response is sent when a malicious backend can insert a Content-Type, Content-Encoding, or some other headers. These issues lead to HTTP response splitting. This CVE provides a "complete" fix for CVE-2023-38709...

org.eclipse.jetty/jetty-server: Eclipse Jetty: Denial of Service due to unreleased JDK Inflater from compressed HTTP requests

A flaw was found in org.eclipse.jetty. A remote attacker can exploit this vulnerability by sending a compressed HTTP request with Content-Encoding: gzip when the server's response is not compressed. This prevents the release of the JDK Inflater, leading to a resource leak. This resource exhaustio...
