CVE-2026-1202505.3 MED—
——0OpenAlgo 1.0.0.29 before 2.0.3.1 contains an improper certificate validation vulnerability in utils/email_utils.py and utils/email_debug.py that disables TLS hostname and certificate checks for STARTTLS and SMTPS. Network-positioned attackers can present a forged certificate to intercept SMTP credentials and all later mail, including password-reset links.1dCVE-2026-1181477.4 ALT—
——0Improper certificate validation in Visual Studio allows an unauthorized attacker to perform spoofing over a network.2dCVE-2026-1176818.0 ALT0.7%
——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.2dCVE-2026-1186979.0 CRÍ20.0%
——6In JetBrains Toolbox App before 3.9.1 and 3.8.2; IntelliJ IDEA before 2026.3 and 2026.2.4, the jetbrainsd daemon trusted compromised intermediate certificates2dCVE-2026-112816—23.1%
——7Improper certificate validation in the HTTPS listener in Canonical LXD 4.0.14, 5.0.10, 5.21.8, 6.9 before 4.0.15, 5.0.11, 5.21.9, 6.10.1 allows an unauthenticated attacker to authenticate as any trusted client and gain full access to the cluster and managed virtual machines via a crafted certificate chain.2dCVE-2026-1195595.9 MED21.6%
——6OpenLiteSpeed 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.3d
