Technical details
The moduleStatelessExecution action was listed in CakePHP's Security component unlockedActions, which disables CSRF token validation. Because the action accepts caller-supplied input and parameters to execute arbitrary workflow modules—including action modules that write to blocklists and warninglists—an attacker could craft a cross-site form post that, when submitted by an authenticated administrator, would execute malicious modules with attacker-controlled input. The vulnerability was fixed in MISP v2.5.47 by removing the action from unlockedActions and implementing proper CSRF token handling via X-CSRF-Token headers.
