CVE-2026-65100

Apache Traffic Server updates the HTTP/2 HPACK dynamic table before confirming the header block encoded successfully, so an encode failure leaves the encoder out of sync with the peer decoder and corrupts subsequent header blocks on the connection. This issue affects Apache Traffic Server: from...

MGASA-2026-0250 Updated haproxy packages fix security vulnerability

HAProxy through 3.4.0, fixed in commit 5985276, contains an integer overflow vulnerability in the fcgiconn structure's drl field that allows buffer misparse as new FCGI record headers. When contentLength is 65535 and paddingLength is 1 or more, the drl field wraps to 0, causing incorrect record...

PYSEC-2026-1427 Connection confusion in gRPC

When gRPC HTTP2 stack raised a header size exceeded error, it skipped parsing the rest of the HPACK frame. This caused any HPACK table mutations to also be skipped, resulting in a desynchronization of HPACK tables between sender and receiver. If leveraged, say, between a proxy and a backend, this...

USN-8459-1: HAProxy vulnerabilities

It was discovered that HAProxy incorrectly handled the FCGI demultiplexer record length field. A remote attacker could possibly use this issue to cause incorrect request routing, response smuggling, or other memory safety issues. CVE-2026-55203 It was discovered that HAProxy failed to validate th...

CVE-2026-55204

HAProxy through 3.4.0, fixed in commit 9a6d1fe, contains a null pointer dereference vulnerability in hpackdhtinsert within src/hpack-tbl.c that fails to validate the return value of hpackdhtdefrag when the memory pool is exhausted. An attacker can trigger HPACK dynamic table insertions under memo...

grpc: client communicating with a HTTP/2 proxy can poison the HPACK table between the proxy and the backend

A flaw was found in Google gRPC due to HPACK table poisoning between the proxy and backend so that other clients see failed requests, resulting in a denial of service. This occurs because the error status for a misencoded header is not cleared between header reads, resulting in subsequent...
