Descripción técnica

Clients may successfully perform a TLS handshake with a MongoDB server despite presenting a client certificate not aligning with the documented Extended Key Usage (EKU) requirements. A certificate that specifies extendedKeyUsage but is missing extendedKeyUsage = clientAuth may still be successfully authenticated via the TLS handshake as a client. This issue is specific to MongoDB servers running on Windows or Apple as the expected validation behavior functions correctly on Linux systems. Additionally, MongoDB servers may successfully establish egress TLS connections with servers that present server certificates not aligning with the documented Extended Key Usage (EKU) requirements. A certificate that specifies extendedKeyUsage but is missing extendedKeyUsage = serverAuth may still be successfully authenticated via the TLS handshake as a server. This issue is specific to MongoDB servers running on Apple as the expected validation behavior functions correctly on both Linux and Windows systems. This vulnerability affects MongoDB Server v7.0 versions prior to 7.0.26, MongoDB Server v8.0 versions prior to 8.0.16 and MongoDB Server v8.2 versions prior to 8.2.2

CVE-2026-1202505.3 MED

——0OpenAlgo 1.0.0.29 before 2.0.3.1 contains an improper certificate validation vulnerability in utils/email_utils.py and utils/email_debug.py that disables TLS hostname and certificate checks for STARTTLS and SMTPS. Network-positioned attackers can present a forged certificate to intercept SMTP credentials and all later mail, including password-reset links.14h CVE-2026-1181477.4 ALT

——0Improper certificate validation in Visual Studio allows an unauthorized attacker to perform spoofing over a network.20h CVE-2026-1176818.0 ALT

——0A flaw was found in konflux-ci. This vulnerability allows privilege escalation when the user interface proxy automatically disables Transport Layer Security (TLS) certificate verification for connections to internal backend services in environments lacking a default service certificate authority. Because the proxy attaches a cluster-scoped authentication token with user impersonation rights to these requests, an adjacent network attacker capable of intercepting traffic can capture the credentials to gain full administrative control of the cluster.1d CVE-2026-1186979.0 CRÍ

——6In JetBrains Toolbox App before 3.9.1 and 3.8.2; IntelliJ IDEA before 2026.3 and 2026.2.4, the jetbrainsd daemon trusted compromised intermediate certificates1d CVE-2026-112816—

——7Improper certificate validation in the HTTPS listener in Canonical LXD 4.0.14, 5.0.10, 5.21.8, 6.9 before 4.0.15, 5.0.11, 5.21.9, 6.10.1 allows an unauthenticated attacker to authenticate as any trusted client and gain full access to the cluster and managed virtual machines via a crafted certificate chain.1d CVE-2026-1195595.9 MED

——6OpenLiteSpeed through 1.9.4 contains an authentication bypass vulnerability that allows unauthenticated remote attackers to evade virtual host client certificate requirements over HTTP/3. Because QuicStream inherits a verifyContext() implementation that always returns true, attackers can present a non-mTLS host's SNI with a protected Host header to access protected content.2d
