JLSEC-2026-669

In wolfSSL before 5.2.0, certificate validation may be bypassed during attempted authentication by a TLS 1.3 client to a TLS 1.3 server. This occurs when the sigalgo field differs between the certificateverify message and the certificate message...

CVE-2026-48747

Summary: CVE-2026-48747 affects Symfony’s Mailomat webhook parser. The MailomatRequestParser::validateSignature() method reads the X-MOM-Webhook-Signature header and passes the wire-provided algorithm directly to hash_hmac(), enabling a signature algorithm downgrade instead of enforcing SHA-256 a...

CVE-2026-50722

A flaw was found in Libreswan's implementation of IKEv2 authentication when processing signatures utilizing the RSASSA-PKCS1-v15 scheme. The RSAauthenticatehashsignaturepkcs115rsa function does not correctly validate the DER encoding of the ASN.1 digest. A remote, unauthenticated attacker could...

EUVD-2026-37016

Crypt::DSA versions before 1.21 for Perl reused the nonce across signatures, leading to private-key recovery. Crypt::DSA::sign caches the per-signature nonce material in the Key object without ever clearing it. The first sign on a Key object picks a nonce, and every later sign on that same object...

CVE-2026-12205

Crypt::DSA for Perl versions before 1.21 reuse the per-signature nonce across signatures because the sign() function caches nonce data in the Key object and does not clear it. The first sign() selects a nonce and later signs reuse that nonce, producing identical r values, enabling potential priva...
