Detailsinfo

A vulnerability classified as problematic has been found in MISP CTI-Transmute up to 1.4.0. Affected is an unknown function of the file /account/delete of the component Administrative User Deletion. The manipulation with an unknown input leads to a cross-site request forgery vulnerability. CWE is classifying the issue as CWE-352. The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. This is going to have an impact on integrity. CVE summarizes:

CTI-Transmute contained a cross-site request forgery vulnerability in the administrative user deletion functionality. The /account/delete/<id> endpoint accepted HTTP GET requests for an operation that modified application state. An unauthenticated remote attacker could construct a malicious link or embed a request targeting this endpoint and induce an authenticated CTI-Transmute administrator to visit the attacker-controlled content. If the administrator had an active session, the browser would automatically include the administrator’s session credentials, causing the selected user account to be deleted without the administrator intentionally confirming the operation. Successful exploitation requires interaction from a currently authenticated administrator who has permission to delete users. The attacker does not need a CTI-Transmute account or administrative privileges because the forged request executes using the victim administrator’s session. The vulnerability could allow an attacker to delete arbitrary user accounts, resulting in unauthorized modification of application state and denial of access for affected users. Depending on whether administrators can delete other administrators or the final administrative account, exploitation could also disrupt administration of the CTI-Transmute instance. The patch resolves the issue by restricting the deletion endpoint to HTTP POST requests and submitting the deletion through a form containing a CSRF token.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2026-69082 since 08/03/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Successful exploitation requires user interaction by the victim. There are known technical details, but no exploit is available.

Applying the patch 4f0d051ec5f1d45894c26987d409411728b2d82c is able to eliminate this problem.
