Hashes mágicos – «colisiones» de hash en PHP Regístrate con contraseña 1 y luego inicia sesión con contraseña 2. Si consigues entrar, entonces el almacenamiento usa el algoritmo especificado para aplicar hash a la contraseña y PHP usa == para compararlas para MD5, SHA-1 y texto plano. MD5, SHA-1,...

CVE-2026-71855

A flaw was found in Suricata. This flaw allows a remote attacker to cause an IPv4 and IPv6 flow to be treated as identical due to a hash collision. This occurs when their raw address words, ports, protocol, VLAN, recursion level, live device, and hash bucket align, without proper comparison of th...

K000163374: Node.js vulnerability CVE-2026-21717

Security Advisory Description A flaw in V8's string hashing mechanism causes integer-like strings to be hashed to their numeric value, making hash collisions trivially predictable. By crafting a request that causes many such collisions in V8's internal string table, an attacker can significantly...

CVE-2026-71855 Suricata flow: IPv4/IPv6 hash collision can reuse wrong flow state

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.17 and 8.0.6, src/flow-hash.c can treat an IPv4 and IPv6 flow as equal without comparing the IP family when their raw address words, ports, protocol, VLAN, recursion...

CVE-2026-71855

The Suricata network security engine (IDS/IPS/NSM) is vulnerable to a hash collision flaw in src/flow-hash.c . Prior to versions 8.0.6 and 7.0.17 , the system can treat IPv4 and IPv6 flows as identical because it fails to compare the IP family when specific attributes—such as raw address words, p...
