CVE-2023-23591Network attack vector

Sensitive-data disclosure via debug log entries

Published Apr 12, 2023 · Updated Feb 10, 2025

Sensitive information exposure in Terminalfour before 8.3.14.1 allows local users with OS administrator access to read application-server logs. When debug logging is enabled, the Logback component writes sensitive application data into server logs without excluding or redacting it. Exploitation requires OS administrator access and debug logging, and the reported consequence is confidentiality loss without integrity or availability impact.
