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.
