| CVE-2026-5501 | 1 Wolfssl | 1 Wolfssl | 2026-04-13 | N/A |
| wolfSSL_X509_verify_cert in the OpenSSL compatibility layer accepts a certificate chain in which the leaf's signature is not checked, if the attacker supplies an untrusted intermediate with Basic Constraints `CA:FALSE` that is legitimately signed by a trusted root. An attacker who obtains any leaf certificate from a trusted CA (e.g. a free DV cert from Let's Encrypt) can forge a certificate for any subject name with any public key and arbitrary signature bytes, and the function returns `WOLFSSL_SUCCESS` / `X509_V_OK`. The native wolfSSL TLS handshake path (`ProcessPeerCerts`) is not susceptible and the issue is limited to applications using the OpenSSL compatibility API directly, which would include integrations of wolfSSL into nginx and haproxy. | ||||
| CVE-2026-35389 | 1 Bulwarkmail | 1 Webmail | 2026-04-10 | 7.5 High |
| Bulwark Webmail is a self-hosted webmail client for Stalwart Mail Server. Prior to 1.4.11, S/MIME signature verification did not validate the certificate trust chain (checkChain: false). Any email signed with a self-signed or untrusted certificate was displayed as having a valid signature. This vulnerability is fixed in 1.4.11. | ||||
| CVE-2026-4740 | 1 Redhat | 1 Multicluster Engine | 2026-04-09 | 8.2 High |
| A flaw was found in Open Cluster Management (OCM), the technology underlying Red Hat Advanced Cluster Management (ACM). Improper validation of Kubernetes client certificate renewal allows a managed cluster administrator to forge a client certificate that can be approved by the OCM controller. This enables cross-cluster privilege escalation and may allow an attacker to gain control over other managed clusters, including the hub cluster. | ||||
| CVE-2026-33753 | 1 Trailofbits | 1 Rfc3161-client | 2026-04-08 | 6.2 Medium |
| rfc3161-client is a Python library implementing the Time-Stamp Protocol (TSP) described in RFC 3161. Prior to 1.0.6, an Authorization Bypass vulnerability in rfc3161-client's signature verification allows any attacker to impersonate a trusted TimeStamping Authority (TSA). By exploiting a logic flaw in how the library extracts the leaf certificate from an unordered PKCS#7 bag of certificates, an attacker can append a spoofed certificate matching the target common_name and Extended Key Usage (EKU) requirements. This tricks the library into verifying these authorization rules against the forged certificate while validating the cryptographic signature against an actual trusted TSA (such as FreeTSA), thereby bypassing the intended TSA authorization pinning entirely. This vulnerability is fixed in 1.0.6. | ||||
| CVE-2025-15612 | 1 Wazuh | 2 Wazuh, Wazuh Provisioning Scripts | 2026-04-08 | 4.8 Medium |
| Wazuh provisioning scripts and Dockerfiles contain an insecure transport vulnerability where curl is invoked with the -k/--insecure flag, disabling SSL/TLS certificate validation. Attackers with network access can perform man-in-the-middle attacks to intercept and modify downloaded dependencies or code during the build process, leading to remote code execution and supply chain compromise. | ||||
| CVE-2026-32144 | 1 Erlang | 3 Erlang/otp, Erlang\/otp, Otp | 2026-04-08 | 7.4 High |
| Improper Certificate Validation vulnerability in Erlang OTP public_key (pubkey_ocsp module) allows OCSP designated-responder authorization bypass via missing signature verification. The OCSP response validation in public_key:pkix_ocsp_validate/5 does not verify that a CA-designated responder certificate was cryptographically signed by the issuing CA. Instead, it only checks that the responder certificate's issuer name matches the CA's subject name and that the certificate has the OCSPSigning extended key usage. An attacker who can intercept or control OCSP responses can create a self-signed certificate with a matching issuer name and the OCSPSigning EKU, and use it to forge OCSP responses that mark revoked certificates as valid. This affects SSL/TLS clients using OCSP stapling, which may accept connections to servers with revoked certificates, potentially transmitting sensitive data to compromised servers. Applications using the public_key:pkix_ocsp_validate/5 API directly are also affected, with impact depending on usage context. This vulnerability is associated with program files lib/public_key/src/pubkey_ocsp.erl and program routines pubkey_ocsp:is_authorized_responder/3. This issue affects OTP from OTP 27.0 until OTP 28.4.2 and 27.3.4.10 corresponding to public_key from 1.16 until 1.20.3 and 1.17.1.2, and ssl from 11.2 until 11.5.4 and 11.2.12.7. | ||||
| CVE-2026-4370 | 1 Canonical | 1 Juju | 2026-04-08 | 10 Critical |
| A vulnerability was identified in Juju from version 3.2.0 until 3.6.19 and from version 4.0 until 4.0.4, where the internal Dqlite database cluster fails to perform proper TLS client and server authentication. Specifically, the Juju controller's database endpoint does not validate client certificates when a new node attempts to join the cluster. An unauthenticated attacker with network reachability to the Juju controller's Dqlite port can exploit this flaw to join the database cluster. Once joined, the attacker gains full read and write access to the underlying database, allowing for total data compromise. | ||||
| CVE-2017-13083 | 1 Akeo | 1 Rufus | 2026-04-07 | N/A |
| Akeo Consulting Rufus prior to version 2.17.1187 does not adequately validate the integrity of updates downloaded over HTTP, allowing an attacker to easily convince a user to execute arbitrary code | ||||
| CVE-2026-34073 | 2 Cryptography.io, Pyca | 2 Cryptography, Cryptography | 2026-04-07 | 5.3 Medium |
| cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to version 46.0.6, DNS name constraints were only validated against SANs within child certificates, and not the "peer name" presented during each validation. Consequently, cryptography would allow a peer named bar.example.com to validate against a wildcard leaf certificate for *.example.com, even if the leaf's parent certificate (or upwards) contained an excluded subtree constraint for bar.example.com. This issue has been patched in version 46.0.6. | ||||
| CVE-2026-25834 | 2 Arm, Mbed-tls | 2 Mbed Tls, Mbedtls | 2026-04-07 | 6.5 Medium |
| Mbed TLS v3.3.0 up to 3.6.5 and 4.0.0 allows Algorithm Downgrade. | ||||
| CVE-2026-20042 | 1 Cisco | 1 Nexus Dashboard | 2026-04-03 | 6.5 Medium |
| A vulnerability in the configuration backup feature of Cisco Nexus Dashboard could allow an attacker who has the encryption password and access to Full or Config-only backup files to access sensitive information. This vulnerability exists because authentication details are included in the encrypted backup files. An attacker with a valid backup file and encryption password from an affected device could decrypt the backup file. The attacker could then use the authentication details in the backup file to access internal-only APIs on the affected device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system as the root user. | ||||
| CVE-2026-32794 | 1 Apache | 2 Airflow Provider For Databricks, Airflow Providers Databricks | 2026-04-03 | 4.8 Medium |
| Improper Certificate Validation vulnerability in Apache Airflow Provider for Databricks. Provider code did not validate certificates for connections to Databricks back-end which could result in a man-of-a-middle attack that traffic is intercepted and manipulated or credentials exfiltrated w/o notice. This issue affects Apache Airflow Provider for Databricks: from 1.10.0 before 1.12.0. Users are recommended to upgrade to version 1.12.0, which fixes the issue. | ||||
| CVE-2024-23273 | 1 Apple | 4 Ipad Os, Iphone Os, Macos and 1 more | 2026-04-02 | 4.3 Medium |
| This issue was addressed through improved state management. This issue is fixed in Safari 17.4, iOS 17.4 and iPadOS 17.4, macOS Sonoma 14.4. Private Browsing tabs may be accessed without authentication. | ||||
| CVE-2025-9293 | 2 Tp-link, Tp Link | 24 Aginet, Aginet App, Deco and 21 more | 2026-04-01 | 8.1 High |
| A vulnerability in the certificate validation logic may allow applications to accept untrusted or improperly validated server identities during TLS communication. An attacker in a privileged network position may be able to intercept or modify traffic if they can position themselves within the communication channel. Successful exploitation may compromise confidentiality, integrity, and availability of application data. | ||||
| CVE-2025-70029 | 2 Sunbird, Sunbird-ed | 2 Sunbirded-portal, Sunbirded-portal | 2026-04-01 | 7.5 High |
| An issue in Sunbird-Ed SunbirdEd-portal v1.13.4 allows attackers to obtain sensitive information. The application disables TLS/SSL certificate validation by setting 'rejectUnauthorized': false in HTTP request options | ||||
| CVE-2026-4396 | 1 Devolutions | 1 Hub Reporting Service | 2026-03-30 | 8.3 High |
| Improper certificate validation in Devolutions Hub Reporting Service 2025.3.1.1 and earlier allows a network attacker to perform a man-in-the-middle attack via disabled TLS certificate verification. | ||||
| CVE-2026-4434 | 1 Devolutions | 2 Devolutions Server, Server | 2026-03-30 | 8.1 High |
| Improper certificate validation in the PAM propagation WinRM connections allows a network attacker to perform a man-in-the-middle attack via disabled TLS certificate verification. | ||||
| CVE-2026-33542 | 2 Linuxcontainers, Lxc | 2 Incus, Incus | 2026-03-30 | 4.8 Medium |
| Incus is a system container and virtual machine manager. Prior to version 6.23.0, a lack of validation of the image fingerprint when downloading from simplestreams image servers opens the door to image cache poisoning and under very narrow circumstances exposes other tenants to running attacker controlled images rather than the expected one. Version 6.23.0 patches the issue. | ||||
| CVE-2019-25652 | 1 Ubiquiti | 1 Unifi Network Controller | 2026-03-30 | 7.5 High |
| UniFi Network Controller before version 5.10.22 and 5.11.x before 5.11.18 contains an improper certificate verification vulnerability that allows adjacent network attackers to conduct man-in-the-middle attacks by presenting a false SSL certificate during SMTP connections. Attackers can intercept SMTP traffic and obtain credentials by exploiting the insecure SSL host verification mechanism in the SMTP certificate validation process. | ||||
| CVE-2026-33248 | 2 Linuxfoundation, Nats | 2 Nats-server, Nats Server | 2026-03-27 | 4.2 Medium |
| NATS-Server is a High-Performance server for NATS.io, a cloud and edge native messaging system. Prior to versions 2.11.15 and 2.12.6, when using mTLS for client identity, with `verify_and_map` to derive a NATS identity from the client certificate's Subject DN, certain patterns of RDN would not be correctly enforced, allowing for authentication bypass. This does require a valid certificate from a CA already trusted for client certificates, and `DN` naming patterns which the NATS maintainers consider highly unlikely. So this is an unlikely attack. Nonetheless, administrators who have been very sophisticated in their `DN` construction patterns might conceivably be impacted. Versions 2.11.15 and 2.12.6 contain a fix. As a workaround, developers should review their CA issuing practices. | ||||
