cti-transmute: Cross-Site Request Forgery
CVE-2026-69082 is a high-severity cross-site request forgery vulnerability in cti-transmute from MISP, with a CVSS 4.0 base score of 8.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected cti-transmute versions: 1.4.0 and earlier. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.27% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of cti-transmute you run against the affected versions below, and install the vendor's latest release.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
Affected products and versions

Official description
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 underlying weakness: Cross-Site Request Forgery
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
How developers prevent this class of flaw
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, use anti-CSRF packages such as the OWASP CSRFGuard. Another example is the ESAPI Session Management control, which includes a component for CSRF.
- Ensure that the application is free of cross-site scripting issues (CWE-79), because most CSRF defenses can be bypassed using attacker-controlled script.
- Generate a unique nonce for each form, place the nonce into the form, and verify the nonce upon receipt of the form. Be sure that the nonce is not predictable (CWE-330).
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: yes, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
