The labels widget gadget in Atlassian Jira before version 7.6.11 and from version 7.7.0 before version 7.13.1 allows remote attackers to inject arbitrary HTML or JavaScript via a cross site scripting (XSS) vulnerability in the rendering of retrieved content from a url location that could be manipulated by the up_projectid widget preference setting.
The Webhooks component of Atlassian Jira before version 7.6.7 and from version 7.7.0 before version 7.11.0 allows remote attackers who are able to observe or otherwise intercept webhook events to learn information about changes in issues that should not be sent because they are not contained within the results of a specified JQL query.
