multiple vulnerabilities as referenced in the USN-6529-1 advisory.

    It was discovered that Request Tracker incorrectly handled certain inputs. If a user or an automated
    system were tricked into opening a specially crafted input file, a remote attacker could possibly use this
    issue to obtain sensitive information. (CVE-2021-38562, CVE-2022-25802, CVE-2023-41259, CVE-2023-41260)
