libcurl 7.7 < 8.21.0 Incomplete mTLS Config Matching in Connection Reuse

The version of libcurl installed on the remote host is 7.7 prior to 8.21.0. It is, therefore, affected by an improper certificate validation vulnerability: - libcurl would reuse a previously created connection even when some mTLS config related option had been changed that should have prohibited...

incomplete mTLS config matching in conn reuse

libcurl would reuse a previously created connection even when some mTLS config related option had been changed that should have prohibited reuse. libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse if one of them matches the setup. However, some TLS...

CVE-2026-53622 Traefik: HTTP/3 mTLS bypass via exact SNI TLSOptions lookup for wildcard and mixed-case hosts

Traefik is an HTTP reverse proxy and load balancer. Prior to 3.7.3, there is a critical vulnerability in Traefik's HTTP/3 QUIC TLS configuration selection that allows unauthenticated clients to bypass router-specific mTLS enforcement. When HTTP/3 is enabled on an entrypoint, the TLS handshake...

CVE-2026-53622

CVE-2026-53622 concerns Traefik’s HTTP/3 (QUIC) TLS configuration selection. When HTTP/3 is enabled, the TLS handshake uses an exact, case-sensitive lookup of the SNI to choose a TLS config, which fails to match wildcard hosts or mixed-case hostnames. If a router enforces mTLS via TLSOptions and ...

Linux Distros Unpatched Vulnerability : CVE-2026-48928

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A inconsistency in Node.js hostname matching can cause a trust-policy bypass in multi-context mTLS setups. This vulnerability affects all supported release line...

@acastellon/auth: Authentication bypass via spoofable headers in validateToken()

@acastellon/auth v2.2.0 appears to allow an unauthenticated authentication bypass in validateToken through spoofable auth-user and Host request headers. The validateToken middleware contains a service-to-service bypass for auth-user: service-brother when req.get'host'.startsWithgetHostName. Both...

CVE-2026-4837

An eval injection vulnerability in the Rapid7 Insight Agent beaconing logic for Linux versions could theoretically allow an attacker to achieve remote code execution as root via a crafted beacon response. Because the Agent uses mutual TLS mTLS to verify commands from the Rapid7 Platform, it is...

DEBIAN-CVE-2026-33343

etcd is a distributed key-value store for the data of a distributed system. Prior to versions 3.4.42, 3.5.28, and 3.6.9, an authenticated user with RBAC restricted permissions on key ranges can use nested transactions to bypass all key-level authorization. This allows any authenticated user with...

Traefik < 2.11.41 / 3.x < 3.6.11 Multiple Vulnerabilities

The version of Traefik installed on the remote macOS host is prior to 2.11.41 or 3.x prior to 3.6.11. It is, therefore, affected by multiple vulnerabilities: - mTLS bypass through the TLS SNI pre-sniffing logic related to fragmented ClientHello packets. When a TLS ClientHello is fragmented across...

CVE-2026-33248

NATS-Server has an authentication bypass vulnerability in mTLS verify_and_map where certain RDN patterns in the client certificate Subject DN were not correctly enforced. A valid certificate from a trusted CA could bypass identity checks on versions prior to 2.11.15 and 2.12.6. The issue is consi...
