CVE-2026-95806

MISP ships with PHP's phar stream wrapper registered in both its web and console entry points. Since no MISP component, vendored CakePHP framework, or runtime-loaded library actually reads or constructs phar archives, the wrapper serves no legitimate purpose and exists solely as an attacker primi...
