CVE-2026-107229
Publication date 8 October 2026
Last updated 8 October 2026
Ubuntu priority
Description
The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. From 2.16.0 until 3.0.14, ThreadSafeCookieStore incompletely validates cookie Domain attributes. Missing private-section and default public-suffix rules, absent A-label normalization, locale-sensitive lowercasing, public-suffix host-only handling, and numeric or IP host checks allow one origin to store a cookie later sent to another origin. Applications sharing one client across trust domains can therefore receive attacker-injected cookies and may be exposed to session fixation. This issue is fixed in version 3.0.14.
