CVE-2026-95806Hinoki check available

Code execution via enabled phar stream wrapper

Published Sep 22, 2026 · Updated Sep 22, 2026

Unsafe deserialization in MISP Project MISP before 2.5.47 allows attackers to execute code via caller-influenced filesystem paths. Both web and console entry points leave PHP's phar wrapper registered, so filesystem operations on a phar path implicitly deserialize archive metadata or reach embedded code. Exploitation requires control of a path resolving to an attacker-supplied phar archive, and resulting code executes with the web process's privileges.
