TL;DR getting an MD5 collision of these two images is now trivial and instant. ⟷ Don't play with fire, don't rely on MD5. Colliding any pair of files has been possible for many years, but it takes several hours each time, with no shortcut. This page provide tricks specific to file formats and...

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...
