CVE-2026-107228
NVD: The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. NVD: From 2.1.0 until 3.0.14, the enabled-by-default cookie store replaces a Cookie header explicitly supplied through setHeader or addHeader whenever the store contributes any cookie for the origin. NVD: In a shared client, stored cookies originating from one user can replace a different user's request cookie, causing the request to execute under the wrong session.
