    Package        : request-tracker4
    CVE ID         : CVE-2025-61873

    It was discovered that Request Tracker, an extensible trouble-ticket
    tracking system is prone to a CSV injection via ticket values with
    special characters that are exported to a TSV from search results.

    For the oldstable distribution (bookworm), this problem has been fixed
    in version 4.4.6+dfsg-1.1+deb12u3.

    We recommend that you upgrade your request-tracker4 packages.

    For the detailed security status of request-tracker4 please refer to its
    security tracker page at:
    https://security-tracker.debian.org/tracker/request-tracker4
