What it is

Affected versions of MISP’s interactive CLI shell do not reliably preserve the identity of the impersonated MISP user across audit logging.

The shell is designed to run actions as a supplied MISP user ID. However, the legacy SysLogLogable behavior stored that identity in behavior-instance state that could be overwritten when another model lazily attached the shared behavior. Consequently, subsequent CLI writes could lose the intended user attribution and be logged incorrectly. The commit also notes that CLI-originated records lacked a CLI marker, making them appear similar to ordinary web actions by that user.

Version affected: ≤2.5.45
