A flaw was found in JSS (Java Security Services). The JSSTrustManager class does not verify NSS trust flags when validating CA certificates, allowing certificates present in the NSS database without TRUSTED_CA flags to be accepted as trust anchors for TLS connections. In non-default configurations where certificate revocation checking is disabled, this could allow a man-in-the-middle attacker to forge certificates accepted by PKI client connections.

CVE-2026-747745.9 MED—
———Dell PowerProtect One, versions 20.1.0.0 and below, contain an Improper Certificate Validation vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to Protection mechanism bypass.2hCVE-2026-810346.5 MED—
———Netmaker disables certificate verification on the connection to the configured mail server. The sender in pro/email/smtp.go assigns a TLS configuration whose skip-verify field is set to true unconditionally, directly beneath a comment stating that the setting should be false in production. No configuration value governs it and no code path restores verification, so the client accepts any certificate the mail server presents, including one an interposing party supplies. Mail that Netmaker sends over that connection includes password-reset messages carrying single-use tokens and user invitations carrying enrolment links, so a party positioned on the path between the server and its mail relay can read those messages in transit and use a captured reset token before the intended recipient does. The setting is absent from the development branch but present in the latest release.1dCVE-2026-650848.1 ALT23.8%
——7NVIDIA NemoClaw for Linux contains a vulnerability in its deployment process, where an attacker could cause improper certificate validation. A successful exploit of this vulnerability might lead to information disclosure, data tampering, code execution, and escalation of privileges.1dCVE-2026-170247.7 ALT16.3%
——5IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a remote attacker to execute arbitrary code due to improper certificate validation.2dCVE-2026-535836.5 MED8.8%
——3libgit2 is a portable C implementation of the Git core methods provided as a linkable library with a solid API, allowing to build Git functionality into your application. Prior to 1.8.6 and 1.9.5, verify_server_cert in src/libgit2/streams/openssl.c uses an inverted !!memcmp result in the GEN_IPADD branch when comparing an IP-literal host with a certificate IP SubjectAltName. OpenSSL builds reject matching IP addresses and accept mismatched IP addresses, allowing a network attacker with a CA-trusted certificate containing any IP SubjectAltName to intercept libgit2 connections to IP-literal HTTPS URLs. DNS SubjectAltName validation and non-OpenSSL TLS backends are not affected. This issue is fixed in versions 1.8.6 and 1.9.5.7dCVE-2026-73253—11.4%
——3Mongoose is an embedded web server and network library. Prior to version 7.22, an on-path network attacker with a wildcard certificate for a parent domain can impersonate deeper subdomains to a client using the built-in TLS stack. The mg_tls_verify_cert_san() and mg_tls_verify_cert_cn() functions in src/tls_builtin.c call mg_match(), whose wildcard can cross DNS label boundaries, so a pattern such as *.example.com can match foo.bar.example.com. The resulting hostname verification bypass permits interception and modification of TLS traffic. This issue is fixed in version 7.22.7d
