CVE-2026-107279

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-2026-18141

The CVE-2026-18141 entry concerns aap-gateway in Ansible Automation Platform’s Event-Driven Ansible (EDA). Affected component: aap-gateway. Vulnerability: an unauthenticated remote attacker can bypass mutual TLS on event streams by manipulating the event stream URL and forging the HTTP Subject he...

CVE-2026-12382 Aap-gateway: missing requestheaderstoremove allows mtls bypass via subject header spoofing

A flaw was found in the AAP Gateway Envoy proxy configuration. The non-mTLS route to EDA event streams does not remove the Subject HTTP header from client requests, despite the source code defining requestHeadersToRemove for this header. An unauthenticated remote attacker can inject a spoofed...

PYSEC-2026-575 wolfSSL Python module vulnerable to Improper Authentication

A vulnerability in the handling of verifymode = CERTREQUIRED in the wolfssl Python package wolfssl-py causes client certificate requirements to not be fully enforced. Because the WOLFSSLVERIFYFAILIFNOPEERCERT flag was not included, the behavior effectively matched CERTOPTIONAL: a peer certificate...

CVE-2026-53622

A flaw was found in Traefik, an HTTP reverse proxy and load balancer. This critical vulnerability in Traefik's HTTP/3 QUIC TLS configuration selection allows unauthenticated clients to bypass router-specific mutual Transport Layer Security mTLS enforcement. When HTTP/3 is enabled and a router use...

CVE-2026-46579

A flaw was found in the OpenShift Router. When a Route has insecureEdgeTerminationPolicy set to Allow, the HTTP frontend does not remove X-SSL-Client- headers from incoming requests. This allows an unauthenticated attacker to send plain HTTP requests with crafted X-SSL-Client- headers. As a resul...

CVE-2026-0073

In adbdtlsverifycert of auth.cpp, there is a possible bypass of wireless ADB mutual authentication due to a logic error in the code. This could lead to remote proximal/adjacent code execution as the shell user with no additional execution privileges needed. User interaction is not needed for...

Improper Authentication

Apache HttpClient is vulnerable to Improper Authentication. The vulnerability is due to a missing verification step in SCRAM-SHA-256 authentication, which allows an attacker to bypass proper mutual authentication checks and be accepted by the client...

EUVD-2026-24630

Missing critical step in authentication in Apache HttpClient 5.6 allows an attacker to cause the client to accept SCRAM-SHA-256 authentication without proper mutual authentication verification. Users are recommended to upgrade to version 5.6.1, which fixes this issue...

SUSE CVE-2026-32305

Traefik is an HTTP reverse proxy and load balancer. Versions 2.11.40 and below, 3.0.0-beta1 through 3.6.11, and 3.7.0-ea.1 are vulnerable to mTLS bypass through the TLS SNI pre-sniffing logic related to fragmented ClientHello packets. When a TLS ClientHello is fragmented across multiple records,...

Traefik has a Potential mTLS Bypass via Fragmented TLS ClientHello Causing Pre-SNI Sniff Fallback to Default Non-mTLS TLS Config

Summary There is a potential vulnerability in Traefik's TLS SNI pre-sniffing logic related to fragmented ClientHello packets. When a TLS ClientHello is fragmented across multiple records, Traefik's SNI extraction may fail with an EOF and return an empty SNI. The TCP router then falls back to the...
