An attacker could craft a URL targeting one of the affected actions and cause an authenticated MISP user with sufficient privileges to request it, for example through a malicious link or embedded web resource.<\/p>\n<p>Successful exploitation could modify the membership of a MISP sharing group without the victim intentionally performing the operation. Depending on the action performed, an attacker could add or remove organisations or servers from a sharing group, potentially granting unintended access to information distributed through that sharing group or disrupting legitimate information sharing.<\/p>\n<p>The patch restores HTTP method enforcement centrally in __initialiseSGQuickEdit() by calling allowMethod([&#8216;post&#8217;]), ensuring that all four affected quick-edit operations require POST requests and are therefore subject to the application&#8217;s normal protections for state-changing requests.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>MISP contains a cross-site request forgery (CSRF) vulnerability in the sharing group quick-edit functionality.
