CVE-2022-46153 1 Traefik 1 Traefik 2026-06-17 8.1 High
Traefik is an open source HTTP reverse proxy and load balancer. In affected versions there is a potential vulnerability in Traefik managing TLS connections. A router configured with a not well-formatted TLSOption is exposed with an empty TLSOption. For instance, a route secured using an mTLS connection set with a wrong CA file is exposed without verifying the client certificates. Users are advised to upgrade to version 2.9.6. Users unable to upgrade should check their logs to detect the error messages and fix your TLS options.
CVE-2025-71261 1 Suse 1 Harvester 2026-06-16 8.6 High
An attacker with network-level access between the SUSE Virtualization and Rancher Manager in SUSE Harvester before 1.8.0 could interfere with the TLS handshake and abuse it to bypass TLS as a security control.
CVE-2026-53475 1 Kubev2v 2 Assisted-migration-agent, Assisted Migration Agent 2026-06-16 9.3 Critical
A flaw was found in assisted-migration-agent. The application hardcodes insecure Transport Layer Security (TLS) connections when communicating with vCenter. This vulnerability allows a Man-in-the-Middle (MITM) attacker to intercept and harvest vCenter administrator credentials. This can lead to unauthorized access to vCenter.
CVE-2026-42769 1 Openssl 1 Openssl 2026-06-15 5.3 Medium
Issue Summary: An error in the callback used to verify the certificate provided in a Root CA key update Certificate Management Protocol (CMP) message response rendered the certificate validation ineffectual, which could lead to escalation of credentials from the Registration Authority (RA) level to the root Certification Authority (root CA) level. Impact Summary: The Registration Autority could replace the root CA certificate for the CMP clients with an arbitrary root CA certificate. One of the parts of the Certificate Management Protocol (CMP), specified in RFC 9810, is Root Certification Authority (root CA) key Rollover, which is sent by the server in a message with type 'id-it-rootCaKeyUpdate'. As part of these messages, 'newWithOld' certificate, the new root CA certificate signed with the old root CA key, is provided, and verifying its signature is crucial for transferring the trust from the old CA key to the new one. The 'id-it-rootCaKeyUpdate' messages are expected to be processed with OSSL_CMP_get1_rootCaKeyUpdate(), that is expected to verify the 'newWithOld' certificate. A typo in the certificate chain building code led to adding an incorrect certificate ('newWithOld' instead of 'oldRoot') to the certificate chain, rendering the certificate verification process ineffectual (only the issuer name and the algorithm OIDs were verified by other parts of the verification code). An attacker who already has credentials that satisfy the CMP message protection checks can generate a new key pair and use a crafted self-signed certificate in its 'id-it-rootCaKeyUpdate' CMP messages which affected CMP clients would accept as a new trust anchor. Significant preconditions for the attack (having valid RA-level credentials) are the reason the issue was assigned Low severity. The FIPS modules are not affected by this issue, as the affected code is outside the OpenSSL FIPS module boundary.
CVE-2026-45175 6 Apple, Cyberark, Cyberark Software A Palo Alto Networks Company and 3 more 6 Macos, Endpoint Privilege Manager, Idira Endpoint Privilege Manager and 3 more 2026-06-12 7.8 High
Idira Endpoint Privilege Manager Agent versions prior to 26.5 exhibit improper access control within internal agent validation processes. A local attacker could potentially bypass built-in security controls or cryptographic validations. Under specific circumstances, this could allow the attacker to circumvent agent self-defense mechanisms and execute unauthorized operations. CyberArk Security Bulletin: CA26-19
CVE-2026-9648 1 Haskell Programming Language 1 Crypton-certificate 2026-06-12 9.1 Critical
The crypton-x509-validation Haskell library fails to enforce X.509 NameConstraints, allowing TLS clients to accept certificates whose Subject Alternative Names fall outside the issuing CA’s permitted subtrees. This oversight enables an attacker who compromises a name-constrained sub-CA to impersonate domains beyond its intended scope.
CVE-2026-9758 1 Systerel 1 S2opc 2026-06-10 7.3 High
Improper comparison with the certificates trusted list in S2OPC allows an attacker well-formed untrusted certificate to be considered trusted
CVE-2026-50752 1 Checkpoint 2 Quantum Security Gateway, Spark Firewalls 2026-06-10 7.4 High
A weakness in the certificate validation logic of the deprecated IKEv1 key exchange may allow an unauthenticated attacker positioned as a man-in-the-middle to bypass certificate validation in VPN site-to-site connections that use certificate-based authentication. Successful exploitation could allow interception or modification of traffic traversing the VPN tunnel.
CVE-2026-41714 2 Spring, Vmware 2 Spring Amqp, Spring Advanced Message Queuing Protocol 2026-06-10 4 Medium

CVE-2026-45745 1 Termix 1 Termix 2026-06-08 8 High
Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. Starting in version 1.7.0, Termix Desktop (Electron) disables TLS certificate validation, allowing a machine-in-the-middle attacker to intercept and modify HTTPS traffic to the configured Termix server. This can lead to credential theft and JWT/session theft during login and normal use. As of time of publication, no known patched versions are available.
CVE-2024-45159 1 Trustedfirmware 1 Mbed Tls 2026-06-05 9.8 Critical
An issue was discovered in Mbed TLS 3.x before 3.6.1. With TLS 1.3, when a server enables optional authentication of the client, if the client-provided certificate does not have appropriate values in if keyUsage or extKeyUsage extensions, then the return value of mbedtls_ssl_get_verify_result() would incorrectly have the MBEDTLS_X509_BADCERT_KEY_USAGE and MBEDTLS_X509_BADCERT_KEY_USAGE bits clear. As a result, an attacker that had a certificate valid for uses other than TLS client authentication would nonetheless be able to use it for TLS client authentication. Only TLS 1.3 servers were affected, and only with optional authentication (with required authentication, the handshake would be aborted with a fatal alert).
CVE-2017-2784 1 Trustedfirmware 1 Mbed Tls 2026-06-05 N/A
An exploitable free of a stack pointer vulnerability exists in the x509 certificate parsing code of ARM mbed TLS before 1.3.19, 2.x before 2.1.7, and 2.4.x before 2.4.2. A specially crafted x509 certificate, when parsed by mbed TLS library, can cause an invalid free of a stack pointer leading to a potential remote code execution. In order to exploit this vulnerability, an attacker can act as either a client or a server on a network to deliver malicious x509 certificates to vulnerable applications.
CVE-2026-25834 2 Mbed-tls, Trustedfirmware 2 Mbedtls, Mbed Tls 2026-06-05 6.5 Medium
Mbed TLS v3.3.0 up to 3.6.5 and 4.0.0 allows Algorithm Downgrade.
