CVE-2026-1176818.0 HIG—
——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.17hCVE-2026-1186979.0 CRI—

——0OpenLiteSpeed 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.1dCVE-2026-92744—17.4%

——5Forge (also called node-forge) is a native implementation of Transport Layer Security in JavaScript. Prior to 1.4.1, node-forge parsed deprecated extension OIDs 2.5.29.10 and 2.5.29.13 as basicConstraints, and pki.verifyCertificateChain() used the first extension with that name. Exploitation requires a CA trusted by the application to issue a certificate carrying an attacker-supplied deprecated-OID extension, commonly because the CA copies extensions from a certificate signing request. By placing a permissive deprecated extension before the genuine 2.5.29.19 basicConstraints extension, the certificate holder could have the certificate accepted as a CA and issue certificates for arbitrary names, enabling server or client impersonation. If the issuing CA adds a keyUsage extension without keyCertSign, node-forge rejects the chain. This issue is fixed in version 1.4.1.1d
