Status: ModifiedMedium (5.9)—

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.

CVSS
