CVE-2026-72759

Name of the Vulnerable Software and Affected Versions MISP cti-transmute (affected versions not specified)

Description An incomplete authorization check exists in the 'conversion-history details' endpoint. When a history record references a deleted conversion, the system returns a null value during the conversion lookup. Because the original logic only denied access if the conversion object existed and failed the visibility check, deleted conversions bypassed this security measure. This allows a user who can request a specific history entry to access the retained input and output data of deleted conversions.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
