[jira] [Updated] (CMIS-1120) unescaped single quotes lead to an OOM exception
[ https://issues.apache.org/jira/browse/CMIS-1120?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Nour Al KOTOB updated CMIS-1120:
--------------------------------
Description:
when we call
{noformat}
org.apache.chemistry.opencmis.server.support.query.QueryUtilBase.processStatement(){noformat}
with a statement containing an unescaped single quote like:
{code:java}
"SELECT cmis:objectId FROM cmis:folder WHERE dc:title = '';'"{code}
or even just
{code:java}
"'';'" {code}
We run into an OOM exception with such stack trace:
{code:java}
