CVE-2026-110354

HAProxy 3 before 3.4.6 allows a remote unauthenticated attacker to cause a denial of service persistent worker-thread CPU exhaustion via an HTTP/1.1 chunked request. Although the H1 multiplexer drains the request before closing the stream, the parser repeatedly re-processes the same bytes without...

CVE-2026-110354

A flaw was found in haproxy. A remote, unauthenticated attacker can trigger a denial of service DoS by sending a specially crafted HTTP/1.1 chunked request. When processing the request, the parser repeatedly re-evaluates the same data without making forward progress, trapping the worker thread in...

CVE-2026-112381

Apache Traffic Server can crash with a null pointer dereference when a client POST request is torn down via half-close while a chunked origin response is being reparsed from a reentrant write-ready callback, a timing-dependent race introduced by the CVE-2021-32564 flow-control backports. This iss...
