The AsyncHttpClient AHC library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. Prior to 3.0.12 and 2.16.1, WebSocketHandler.upgrade aborts a handshake whose Sec-WebSocket-Accept value is missing or invalid but continues into pipeline installati...

CVE-2026-107283

The AsyncHttpClient (AHC) library for Java applications is vulnerable to reduced authentication security due to the use of a non-cryptographic random source. In versions prior to 3.0.12 and 2.16.1 , the Realm.Builder component generates the HTTP Digest client nonce using ThreadLocalRandom instead...

CVE-2026-107283 AsyncHttpClient: Digest authentication cnonce generated with a non-cryptographic random source

The AsyncHttpClient AHC library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. Prior to 3.0.12 and 2.16.1, Realm.Builder generates the HTTP Digest client nonce with ThreadLocalRandom rather than a cryptographically secure random source. Digest...

CVE-2026-107282

The AsyncHttpClient (AHC) library, used in Java applications, contains a cross-host request replay vulnerability in versions prior to 3.0.13 and 2.16.1 . The root cause is that request replays update the current request but retain the target request and proxy context of the original origin. This ...

CVE-2026-107282 AsyncHttpClient: Replay to a different host sends the original host request and credentials to the new host

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-2026-105818

The Vault PKI secrets engine ACME server is vulnerable to an issue where it fails to restrict certificate identities that ACME challenges do not validate when using the default directory policy . This flaw allows an ACME client to obtain a certificate containing unverified identity claims , poten...

CVE-2026-105818 Vault PKI ACME Issues Certificate With Unvalidated SANs

Vault's PKI secrets engine ACME server did not restrict certificate identities that ACME challenges do not validate when issuing certificates under the default directory policy. This may allow an ACME client to obtain a certificate containing unverified identity claims, potentially enabling...

CVE-2026-107281

The AsyncHttpClient (AHC) library, used by Java applications for asynchronous HTTP requests, is vulnerable to an identity mismatch issue in versions prior to 3.0.13 and 2.16.1 . The root cause is that the HTTP/1.1 connection-pool key omits the authenticated principal for NTLM and Negotiate authen...

CVE-2026-107281 AsyncHttpClient: Connection pool key omits the authenticated principal, so an NTLM or Negotiate connection is reused across identities

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, the HTTP/1.1 connection-pool key excludes the authenticated principal for connection-oriented NTLM and Negotiate authentication. A pooled...

CVE-2026-107280

The AsyncHttpClient (AHC) library for Java applications is vulnerable to a cookie injection or overwriting issue in versions prior to 3.0.13 and 2.16.1 . The root cause is that the ThreadSafeCookieStore component validates Domain attributes using domain matching but fails to reject public suffixe...

CVE-2026-107280 AsyncHttpClient: Cookie Domain attribute is not checked against the public suffix list, so a cookie can be set for co.uk

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, ThreadSafeCookieStore validates Domain attributes with domain matching but does not reject public suffixes. A host beneath a suffix such ...

CVE-2026-107279 AsyncHttpClient: Digest mutual authentication is switched off by a peer offering qop=auth-int

The AsyncHttpClient AHC library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. In 3.0.12, a peer offering only Digest qop=auth-int causes mutual-authentication verification to be skipped. AuthenticatorUtils.computeExpectedRspAuth returns no...

CVE-2026-107279

The AsyncHttpClient (AHC) library, used by Java applications for asynchronous HTTP requests, is vulnerable in version 3.0.12 . The root cause is that a peer offering only Digest qop=auth-int causes mutual-authentication verification to be skipped. Specifically, AuthenticatorUtils.computeExpectedR...

CVE-2026-107232

The AsyncHttpClient (AHC) library for Java applications is vulnerable to cleartext credential transmission in versions prior to 3.0.12 (3.x) and 2.16.1 (2.x) . The root cause is that the client incorrectly infers an active HTTP proxy tunnel based on the last request method rather than the CONNECT...

CVE-2026-107232 AsyncHttpClient: Origin credentials sent in cleartext to a proxy that rejects the CONNECT

The AsyncHttpClient AHC library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. Prior to 3.0.12 on 3.x and 2.16.1 on 2.x, the client infers that an HTTP proxy tunnel exists from the last request method rather than the CONNECT result. After a pro...

CVE-2026-107231

The AsyncHttpClient (AHC) library for Java applications is vulnerable to an authentication downgrade attack in versions prior to 3.0.13 and 2.16.1 . The Realm.Builder component incorrectly treats a Digest challenge that lacks a usable nonce as a Basic challenge . An attacker controlling a proxy o...

CVE-2026-107231 AsyncHttpClient: Digest challenge without a usable nonce downgrades to Basic and sends the password in cleartext

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-2026-107230

The AsyncHttpClient (AHC) Java library, from version 2.0.0 until 3.0.14 , contains a vulnerability where connection-pool partitioning fails to omit identity-defining fields for Kerberos, SPNEGO, NTLM , and authenticated proxy connections. This flaw allows logins lacking configured principals, pro...

CVE-2026-107230 AsyncHttpClient: Pooled connections can still be shared across NTLM, Negotiate and proxy logins

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-2026-107229

The AsyncHttpClient (AHC) library for Java applications contains a vulnerability in the ThreadSafeCookieStore component. From version 2.16.0 until 3.0.14 , the library incompletely validates cookie Domain attributes due to missing private-section and public-suffix rules, lack of A-label normaliza...
