description

Affected Splunk Enterprise releases can fail to enforce risky-command restrictions when searches are run on a schedule. A user with the schedule_search capability may use this path to perform operations that expose or modify data or impair service availability.

mitigation

Upgrade Splunk Enterprise to 10.4.4, 10.2.8, 10.0.11, or 9.4.16, as appropriate for your release line. Until upgraded, remove or tightly limit the schedule_search capability for untrusted roles.

fixed in 10.4.4, 10.2.8, 10.0.11, 9.4.16
