Short Paper: Prefix Count Limits Can Increase First-Hit Discovery in Card Reissuance

When a card number is compromised, an attacker may search for active numbers sharing its prefix. An issuer might respond by reissuing cards from heavily populated prefixes into less populated ones. We show that this intuitive count control can backfire. For fixed search regions, exposure weights,...

CVE-2026-97472

The Linux kernel contains a vulnerability in the ipv6 addrconf component where the system permanently loses the ability to generate temporary privacy addresses (RFC 8981) for a prefix after it has been temporarily deprecated and subsequently restored by a router. The root cause is that the addres...

CVE-2026-97472: Undefined Security Weakness

gitpython: GitPython: Command Injection via Git option prefix abbreviation

A flaw was found in GitPython. This vulnerability stems from an incomplete command injection blocklist that fails to account for Git's long-option prefix abbreviation feature. An attacker can bypass existing security measures by using abbreviated option names, which Git then resolves to dangerous...
