Ubuntu 22.04 LTS / 24.04 LTS / 25.10 / 26.04 LTS : Libgcrypt vulnerabilities (USN-8319-1)

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.10 / 26.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8319-1 advisory. It was discovered that Libgcrypt incorrectly handled crafted ECDH ciphertext. An attacker could possibly use this issue t...

Improper Authentication

Overview Affected versions of this package are vulnerable to Improper Authentication via the buildSpCertificateStore function. An attacker can gain unauthorized access by supplying a malicious signing certificate in the SAMLResponse, which is accepted instead of the trusted pre-configured Identit...

CVE-2026-45021

Kuma is a modern Envoy-based service mesh that can run on every cloud across both Kubernetes and VMs. Prior to 2.7.25, 2.9.15, 2.11.13, 2.12.10, and 2.13.5, the default kuma-cp config leaks the admin bootstrap token and signing keys to any webpage the operator visits while the control plane is...

CVE-2026-45021

Kuma CVE-2026-45021 describes a cross-origin exposure in the default kuma-cp config where CorsAllowedDomains: "." and LocalhostIsAdmin: true enable a browser-based attacker to fetch admin credentials from the control plane. Before versions 2.7.25, 2.9.15, 2.11.13, 2.12.10, and 2.13.5, a malicious...

CVE-2026-9090

Casdoor versions 2.362.0 and earlier contain a vulnerability that allows an attacker to bypass authentication by supplying an arbitrary signing certificate. The buildSpCertificateStore function extracts the X.509 certificate directly from the incoming SAMLResponse instead of using the trusted...

Improper Cleanup on Thrown Exception

Overview Affected versions of this package are vulnerable to Improper Cleanup on Thrown Exception via the getsigningkey function. An attacker can exhaust system resources by sending numerous JWTs with attacker-controlled kid values, causing repeated outbound requests to the JWKS endpoint. Note:...

CVE-2026-9090

Casdoor versions 2.362.0 and earlier are affected by an authentication bypass when the buildSpCertificateStore function extracts the X.509 certificate directly from the incoming SAMLResponse instead of using the trusted IdP certificate. This allows forging SAML assertions with an attacker‑control...
