CVE-2026-107227: Uncontrolled Resource Consumption

The AsyncHttpClient AHC library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. From 2.2.0 until 3.0.14, WebSocket permessage-deflate decompression is unbounded when compression is enabled. The inbound pipeline aggregates compressed frames befor...

CVE-2026-107230: Origin Validation Error

The AsyncHttpClient AHC library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. From 2.0.0 until 3.0.14, connection-pool partitioning still omits identity-defining fields for Kerberos, SPNEGO, NTLM, and authenticated proxy connections. Logins...

CVE-2026-107231: Cleartext Transmission of Sensitive Information

The AsyncHttpClient AHC library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. Prior to 3.0.13 and 2.16.1, Realm.Builder treats a Digest challenge that yields no usable nonce as a Basic challenge. A malicious origin or proxy can label a challen...

CVE-2026-107282: Cleartext Transmission of Sensitive Information

The AsyncHttpClient AHC library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. Prior to 3.0.13 and 2.16.1, cross-host request replay updates the current request but leaves the target request and related proxy context pointing at the original...

CVE-2026-85719

A flaw was found in AsyncHttpClient. This vulnerability allows an attacker to expose SOCKS proxy credentials to the origin server when using an authenticated SOCKS proxy. This occurs because the library attaches Proxy-Authorization headers without verifying if the request is being sent to an HTTP...

CVE-2026-85716

A flaw was found in the AsyncHttpClient AHC library. This vulnerability allows a remote attacker to impersonate the server on a non-TLS Transport Layer Security or compromised network. The library's authentication process for SCRAM and Digest mutual-authentication does not properly verify server...

CVE-2026-85718

A flaw was found in AsyncHttpClient. When configured with connection limits, the library can leak a connection permit if a Transport Layer Security TLS handshake fails before completion. This permit leak can lead to resource exhaustion, allowing a remote attacker to cause a denial of service by...

CVE-2026-85721

A flaw was found in AsyncHttpClient's automatic HTTP response decompression. With automatic decompression enabled the default, the HTTP/1.1 path does not limit the total decompressed response size. A hostile or compromised server, or an attacker able to change a response in transit, can send a...

GHSA-F8M2-889X-VW4X AsyncHttpClient re-sends client-wide realm credentials to a cross-origin redirect target

Impact A client configured with a client-wide realm a Realm set on the config builder rather than on an individual request and following redirects could re-send those credentials to a redirect target on a different origin. The redirect code strips the per-exchange realm, but when the target...

GHSA-XR57-GCX8-52HF AsyncHttpClient sends origin credentials to the proxy on the plaintext CONNECT request

Impact When a request uses an HTTP proxy to reach an HTTPS origin, the client opens the tunnel with a plaintext CONNECT sent to the proxy before any TLS exists. On affected versions the origin's preemptive credentials were added to that CONNECT. A Basic realm sent Authorization: Basic...
