Improper Certificate Validation

kubevirt.io/kubevirt is vulnerable to improper certificate validation. The vulnerability is due to flawed peer verification logic in virt-handler, which allows an attacker to exploit shared credentials from a compromised instance to impersonate virt-api and execute privileged operations on other...

CVE-2026-35586

The vulnerability CVE-2026-35586 affects pyload-ng and stems from an incorrect admin-only configuration guard: the ADMIN_ONLY_CORE_OPTIONS set uses ssl_cert and ssl_key instead of the actual ssl_certfile and ssl_keyfile names, and ssl_certchain was not included. This lets any non-admin user with ...

CVE-2026-35586 Authorization Bypass for SSL Certificate/Key Configuration Due to Option Name Mismatch in pyload-ng

pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev97, the ADMINONLYCOREOPTIONS authorization set in setconfigvalue uses incorrect option names sslcert and sslkey, while the actual configuration option names are sslcertfile and sslkeyfile. This name mismatch...

curl: Public key pinning bypass via QUIC and GnuTLS allows server impersonation

A flaw was found in curl. When configured to use public key pinning with QUIC connections and GnuTLS, and with standard certificate verification explicitly disabled, curl could bypass the intended public key check. This oversight allows a malicious server to impersonate a legitimate one,...

curl: libcurl: Improper certificate validation due to cached TLS settings reuse

A flaw was found in libcurl. When handling secure connections TLS and reusing connection settings, libcurl could incorrectly apply a cached security setting related to certificate chain validation. This could allow libcurl to accept a server's security certificate that it should have otherwise...
