The Apache Openofffice project reports:

    CVE-2020-13958 Unrestricted actions leads to arbitrary code execution in
    crafted documents

    Description

    A vulnerability in Apache OpenOffice scripting events allows an attacker to
    construct documents containing hyperlinks pointing to an executable on the
    target users file system. These hyperlinks can be triggered
    unconditionally. In fixed versions no internal protocol may be called from
    the document event handler and other hyperlinks require a control-click.

    Severity: Low

    There are no known exploits of this vulnerability.
    A proof-of-concept demonstration exists.

    Thanks to the reporter for discovering this issue.

    Acknowledgments

    The Apache OpenOffice Security Team would like to thank Imre Rad for
    discovering and reporting this attack vector.
