The likelihood of exploitation is unclear due to the absence of EPSS data, but the impact on confidentiality is significant if an attacker gains administrator access."}}}}, "created": "2026-03-27T08:33:52.122156+00:00", "updated": "2026-03-27T09:26:18.341404+00:00", "vendors": ["mattermost", "mattermost$PRODUCT$mattermost"]}
