CVE-2026-84197 Crítica · 9.2 CWE-295 08/09/2026
Improper Certificate Validation em Eclipse Foundation Eclipse Ditto
In Eclipse Ditto's Node.js JavaScript client, all released versions of @eclipse-ditto/ditto-javascript-client-node from 2.0.0 to 3.9.0 and of its predecessor package @eclipse-ditto/ditto-javascript-client-node_1.0 from 1.0.0 to 2.1.0, the WebSocket transport hard-codes rejectUnauthorized: false when creating the underlying ws WebSocket. Certificate chain and hostname validation are therefore disabled for every wss:// connection, and no builder option, constructor argument or environment variable lets an application turn validation back on. An attacker in a position to intercept the connection can present an arbitrary certificate, complete the TLS handshake, read the credentials that the configured authentication provider sends in the Authorization header of the WebSocket upgrade request, and read, alter or inject Ditto Protocol messages for the lifetime of the connection. The Java client, the browser/DOM JavaScript client and the HTTP transport of the Node.js client are not affected.
CVE-2026-78234 Crítica · 9.9 CWE-295 08/09/2026
Hawtio-operator: hawtio-operator: service-ca signing oracle allows arbitrary-cn certificate issuance to namespace edit users
A flaw was found in hawtio-operator. The operator reads the OpenShift Service CA private signing key from the openshift-service-ca namespace and uses it to mint client certificates with a Subject Common Name (CN) supplied by the author of a namespaced Hawtio custom resource. Because the operator ships a ClusterRole that aggregates Hawtio CR permissions into the edit and admin roles, any user with edit access in any namespace can obtain a Service-CA-signed certificate with an arbitrary subject. This certificate can be used to impersonate any in-cluster service identity to peers that trust the Service CA for client authentication, including Jolokia agents and other Service-CA-trusting components.

CVE-2026-82208 Alta · 7.5 CWE-295 06/09/2026
wolfSSL CA-cache hit overrides callback
With the wolfSSL backend, when CA caching is enabled and an `CURLOPT_SSL_CTX_FUNCTION` callback replaces the trust store, libcurl can silently reinstall the cached store after the callback returns. A certificate trusted by the cached store but rejected by the callback-selected store is then incorrectly accepted.
CVE-2026-80230 Alta · 7.5 CWE-295 06/09/2026
OpenSSL pinning bypass
When `CURLOPT_PINNEDPUBLICKEY` is configured alongside options that disable standard peer verification (`CURLOPT_SSL_VERIFYPEER = 0` and `CURLOPT_SSL_VERIFYHOST = 0`), libcurl fails to enforce public key pinning on connections established without a presented server certificate. Bypassing the pinning check under these disabled-verification conditions allows unauthenticated connections to succeed when they should be rejected.
CVE-2026-86185 Alta · 8.0 CWE-295 05/09/2026
Bilibili Desktop through 1.18.0 Remote Code Execution via TLS Verification Bypass
Bilibili Desktop through 1.18.0 disables TLS certificate verification process-wide and executes unsigned remote JavaScript configuration without integrity checks. An attacker in an on-path network position can intercept configuration fetches, inject arbitrary JavaScript executed in the renderer with access to the privileged IPC bridge, and execute system commands or steal login credentials.
CVE-2026-84961 Crítica · 9.1 CWE-295 04/09/2026
undici vulnerable to TLS certificate validation bypass via dropped connect options in BalancedPool
undici's BalancedPool constructor passes its entire options object through an internal deep-clone that serializes and reparses the value as JSON. Because JSON cannot represent functions, any function-valued TLS option, such as a caller-supplied checkServerIdentity callback or a custom connector inside the connect option, is silently discarded before it reaches the TLS layer. As a result a peer whose certificate the application's custom checkServerIdentity was written to reject, but which still passes Node's default hostname and chain checks, is accepted when reached through BalancedPool. The Client, Pool, and Agent dispatchers are not affected because they extract the connect and tls options before cloning. This affects undici versions from 7.24.1 up to 7.29.1 and from 8.0.0 up to 8.10.2, and only when the application supplies a function-valued connect or tls option to BalancedPool. Users should upgrade to undici 7.29.1 or 8.10.2.
CVE-2026-85525 Alta · 7.4 CWE-295 04/09/2026
Improper OCSP response validation in Snowflake drivers
Improper OCSP response validation in the Snowflake Python, Go, JDBC, and Node.js drivers allowed a revoked TLS certificate to be accepted as valid, because OCSP responses were not reliably bound to the certificate being validated and definitive verification failures were treated as transient. A man-in-the-middle attacker holding a revoked certificate and its private key for a Snowflake or stage hostname could cause the driver to establish a TLS session to the attacker-controlled endpoint anyway, allowing the attacker to read and modify data transmitted within that connection. Successful exploitation requires that on-path position and the corresponding private key, and impact is limited to data carried within the intercepted connection. The fix is available in Snowflake Connector for Python v4.7.3, Snowflake Go Driver v2.2.0, Snowflake JDBC Driver v4.3.4 (including the snowflake-jdbc-fips and snowflake-jdbc-thin), and Snowflake Node.js Driver v3.3.0. Users must manually upgrade.
CVE-2026-15937 Média · 5.3 CWE-295 04/09/2026
Agent receiver certificate confusion allows authentication with a certificate issued for another endpoint
Improper certificate validation in Checkmk <2.5.0p10 allows a relay and a push agent that share the same UUID to reuse each other's mTLS certificate to authenticate against agent receiver endpoints in either direction, because the endpoints do not verify that the certificate was issued by their own root certificate.
CVE-2026-9036 Média · 5.9 CWE-295 03/09/2026
Vulnerabilities exists in IBM Netezza Software
IBM Netezza Software 11.3.0.3 through Interim Fix 002 does not validate or improperly validates TLS certificate validation, which could allow an attacker to obtain sensitive information using man in the middle techniques.
CVE-2026-84736 Alta · 8.3 CWE-295 03/09/2026
Improper Certificate Validation em Eclipse Foundation Eclipse aeriOS
In the current development version of Eclipse aeriOS, for which no official release has yet been published, the Federator component disables TLS certificate validation for outbound HTTPS connections by default. When the TLS_CERTIFICATE_VALIDATION environment variable is unset or set to false, the component configures its HTTP transport to skip TLS certificate verification. As a result, an attacker able to intercept network communications between the Federator and external services could impersonate those services and intercept sensitive information transmitted over HTTPS, including OAuth client credentials and bearer tokens. The issue has been addressed by enabling TLS certificate validation by default. The TLS_CERTIFICATE_VALIDATION environment variable is now set to true in the default configuration provided by the Helm chart and Docker Compose deployment.
CVE-2026-85221 Crítica · 9.1 CWE-295 03/09/2026
MISP CurlClient TLS Peer Verification Disabled by Default Enables Man-in-the-Middle Attacks
MISP contains an improper TLS certificate validation vulnerability in CurlClient. The CurlClient::$verifyPeer property was not explicitly initialized and therefore defaulted to null. When passed to cURL, this value effectively disabled TLS peer verification unless the calling code explicitly enabled it. As a result, HTTPS connections made through affected CurlClient instances could accept certificates that were not issued by a trusted certificate authority. An attacker capable of intercepting or manipulating network traffic between a MISP instance and a remote HTTPS service could impersonate the remote endpoint and perform a man-in-the-middle attack. Successful exploitation could allow an attacker to observe sensitive information transmitted by MISP, including authentication material or exchanged threat intelligence, and to modify responses returned to the MISP instance. The impact depends on the functionality using CurlClient and the data exchanged with the remote service. The patch enables TLS peer verification by default while preserving explicit support for configured self-signed certificates. It also corrects the self-signed certificate handling in SyncTool so that peer verification is disabled only when no pinned CA certificate is configured.
CVE-2026-82955 Crítica · 9.0 CWE-295 02/09/2026
Improper Certificate Validation em Eclipse Foundation Eclipse aeriOS
In the current development version of Eclipse aeriOS, which has not yet had an official release, the KrakenD instance included in the API Gateway component had the disable_jwk_security parameter hard-coded to true, with no option to override it through the Helm chart configuration. This setting disables TLS certificate verification when KrakenD retrieves the JSON Web Key Set (JWKS) used to validate bearer tokens, potentially allowing an attacker with the ability to intercept this communication to provide a malicious JWKS and compromise token validation. The issue has been addressed by making the parameter configurable through the boolean Helm value krakend.config.disableJwkSecurity and setting its default value to false, ensuring that TLS certificate verification is enabled by default.
CVE-2026-82662 Média · 6.5 CWE-295 31/08/2026
Nodemailer before 8.0.8 TLS Certificate Validation Bypass
Nodemailer before 8.0.8 disables TLS certificate verification in lib/fetch/index.js through rejectUnauthorized: false, allowing attackers to intercept OAuth2 token requests. Attackers in a machine-in-the-middle position can capture OAuth client secrets, refresh tokens, and access tokens transmitted over compromised HTTPS connections.
CVE-2026-41012 Alta · 7.7 CWE-295 29/08/2026
BOSH vSphere CPI Improper Cert Validation
Traffic interception vulnerability in BOSH Director vCenter CPI allows attackers positioned between BOSH Director and vCenter to impersonate vCenter REST API and capture administrator credentials via HTTP Basic auth, leading to complete virtualization infrastructure takeover. An attacker who can intercept traffic between the BOSH Director and vCenter can establish a malicious server impersonating the vCenter REST API. When the BOSH Director makes CPI calls to perform routine cloud infrastructure operations, the attacker captures the vCenter administrator username and password transmitted via HTTP Basic authentication. The vulnerability stems from insufficient authentication security in the communication protocol between BOSH Director and vCenter. While HTTPS may be used, the lack of proper certificate validation and pinning allows attackers to successfully impersonate vCenter endpoints. Because vCenter credentials typically grant full administrative control over the entire virtualization estate, successful credential capture yields complete takeover of every VM, datastore, and network the CPI manages. This exposure exists on every CPI call (including routine deployment operations, not just when tags are configured) and cannot be mitigated by supplying a CA certificate alone. The attack impacts all infrastructure managed by the compromised vCenter instance, potentially affecting hundreds or thousands of VMs across multiple deployments and environments.
