Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') (CWE-22) in the Kibana Fleet feature can lead to the unauthorized deletion of privileged resources via Path Traversal (CAPEC-126). A low-privileged user holding Fleet Settings write access could cause a subsequent administrative action to act on unintended internal resources, resulting in the deletion of privileged resources such as user accounts and other organizational assets. Exploitation requires an administrator to interact with the affected Fleet interface.
AnalysisAI
Path traversal in Kibana's Fleet feature enables a low-privileged attacker with Fleet Settings write access to plant a malicious pathname in settings that, when subsequently acted upon by an administrator, causes deletion of privileged internal resources including user accounts and organizational assets. All Kibana versions prior to 8.19.18, 9.3.6, and 9.4.3 are affected per ESA-2026-158. …
