The actions setTheme, setHomePage, and eventIndexColumnToggle were explicitly added to the Security component&#8217;s unlockedActions list, which disabled all CSRF validation (both token and field-hash checks) for those endpoints. Because these endpoints accept POST requests and modify per-user application state (theme selection, default homepage URL, and event index column visibility), an attacker who can induce a logged-in MISP user to load a malicious page (e.g., via a crafted link, embedded image, or auto-submitting form) can forge requests that alter the victim&#8217;s settings without their knowledge or consent. The most impactful action is setHomePage, which allows an attacker to redirect the victim&#8217;s default landing page to an arbitrary attacker-controlled URL, potentially facilitating phishing or further social engineering. The setTheme action can alter the user&#8217;s visual theme, and eventIndexColumnToggle can change which columns are displayed in the event index view. No authentication bypass is involved; the victim must already be authenticated to MISP. The vulnerability was reported by the Scottish Government National Cyber Team.<\/p>\n<p>Version affected: \u22642.5.45<\/p>\n","protected":false},"excerpt":{"rendered":"<p>MISP contains a Cross-Site Request Forgery (CSRF) vulnerability in the UserSettingsController.
