CVE-2026-9758

Improper comparison with the certificates trusted list in S2OPC allows an attacker well-formed untrusted certificate to be considered trusted...

CVE-2026-52754

Ghidra before 12.1 contains an authentication bypass vulnerability in PKIAuthenticationModule.authenticate that allows any user with a valid CA-signed certificate to impersonate other users by presenting their public certificate with a null signature. Attackers can escalate privileges, modify...

CVE-2026-9648 CVE-2026-9648

The crypton-x509-validation Haskell library fails to enforce X.509 NameConstraints, allowing TLS clients to accept certificates whose Subject Alternative Names fall outside the issuing CA’s permitted subtrees. This oversight enables an attacker who compromises a name-constrained sub-CA to...

CVE-2026-9648

The CVE-2026-9648 affects the crypton-x509-validation (and related crypton-x509) libraries used in Haskell TLS stacks. The root cause is the failure to enforce X.509 NameConstraints, allowing a TLS client to accept SANs outside the issuing sub-CA’s permitted subtrees. This enables an attacker who...

crypto/tls: crypto/tls: Incorrect certificate validation during TLS session resumption

A flaw was found in the crypto/tls component. This vulnerability occurs during Transport Layer Security TLS session resumption when certificate authority CA settings are modified between the initial and resumed handshakes. An attacker could exploit this to bypass certificate validation, allowing ...

crypto/x509: crypto/tls: golang: Go: Denial of Service vulnerability in certificate chain building

A flaw was found in the Go standard library packages crypto/x509 and crypto/tls. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being...

crypto/x509: golang: Denial of Service due to excessive resource consumption via crafted certificate

A flaw was found in golang. A remote attacker could exploit this vulnerability by providing a specially crafted certificate during the error string construction process within the HostnameError.Error function. This flaw, caused by unbounded string concatenation, leads to excessive resource...

crypto/x509: crypto/tls: golang: Go: Denial of Service vulnerability in certificate chain building

A flaw was found in the Go standard library packages crypto/x509 and crypto/tls. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being...

crypto/x509: golang: Go crypto/x509: Denial of Service via inefficient certificate chain validation

A flaw was found in Go's crypto/x509 package. A remote attacker could exploit this by presenting a specially crafted certificate chain containing a large number of policy mappings. This inefficient validation process consumes excessive resources, which can lead to a denial of service DoS for...
