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-2026-97468

A flaw was found in Apache CXF. The Security Token Service STS and token validation components cache validated security tokens using a weak, non-cryptographic hash function and treat cache matches as proof of validity. A remote attacker can craft a security token that generates a hash collision...

CVE-2026-97468

Apache CXF's STSTokenValidator and Security Token Service STS cached validated security tokens under a non-cryptographic 32-bit hash of the token Java Arrays.hashCode/hashCode, and treated a cache hit as proof that the presented token had already been validated. An attacker could craft a token fo...

CVE-2026-97468

Apache CXF 's STSTokenValidator and Security Token Service (STS) are vulnerable to an authentication bypass because they cache validated security tokens using a weak, non-cryptographic 32-bit hash (Java Arrays.hashCode/hashCode() ). A remote attacker can craft a security token, such as a Username...

CVE-2026-97468 Apache CXF: Authentication bypass via weak cache keys for validated STS tokens

Apache CXF's STSTokenValidator and Security Token Service STS cached validated security tokens under a non-cryptographic 32-bit hash of the token Java Arrays.hashCode/hashCode, and treated a cache hit as proof that the presented token had already been validated. An attacker could craft a token fo...

Astra Linux – Vulnerability in jq

jq is a command-line JSON processor. Before commit 0c7d133c3c7e37c00b6d46b658a02244fdd3c784, jq used MurmurHash3 with a hardcoded, publicly visible seed 0x432A9843 for all JSON object hash table operations. This allowed attackers to precompute key collisions offline. By providing a crafted JSON...

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

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...
