CVE-2026-74871

The jahlives/openssl_encrypt PHP package before 1.4.6 has a KDF bypass: in sequential XOR composition mode the final stage cancels out, so attackers with local access can crack passwords at SHA-256 speed instead of the configured memory-hard KDF cost. CVSS 6.2 (MEDIUM, local). No in-the-wild expl...

openssl: FFC-DH Peer Validation Uses Attacker-Supplied q

A flaw was found in OpenSSL. A malicious peer can exploit this vulnerability by presenting a specially crafted DHX X9.42 peer key. Due to improper validation of the peer key's subgroup membership, an attacker can recover the victim's private key after a small number of key exchange attempts. This...
