The /rest/api/latest/groupuserpicker resource in Jira before version 8.4.0 allows remote attackers to enumerate usernames via an information disclosure vulnerability.
Various templates of the Optimization plugin in Jira before version 7.13.6, and from version 8.0.0 before version 8.4.0 allow remote attackers who have permission to manage custom fields to inject arbitrary HTML or JavaScript via a cross site scripting (XSS) vulnerability in the name of a custom field.
The /plugins/servlet/gadgets/makeRequest resource in Jira before version 8.4.0 allows remote attackers to access the content of internal network resources via a Server Side Request Forgery (SSRF) vulnerability due to a logic bug in the JiraWhitelist class.
The /rest/api/1.0/render resource in Jira before version 8.4.0 allows remote anonymous attackers to determine if an attachment with a specific name exists and if an issue key is valid via a missing permissions check.
The FilterPickerPopup.jspa resource in Jira before version 7.13.7, and from version 8.0.0 before version 8.3.3 allows remote attackers to inject arbitrary HTML or JavaScript via a cross site scripting (XSS) vulnerability in the searchOwnerUserName parameter.
The AccessLogFilter class in Jira before version 8.4.0 allows remote anonymous attackers to learn details about other users, including their username, via an information expose through caching vulnerability when Jira is configured with a reverse Proxy and or a load balancer with caching or a CDN.
The Webwork action Cross-Site Request Forgery (CSRF) protection implementation in Jira before version 8.4.0 allows remote attackers to bypass its protection via "cookie tossing" a CSRF cookie from a subdomain of a Jira instance.
There was a local file disclosure vulnerability in Confluence Server and Confluence Data Center via page exporting. An attacker with permission to editing a page is able to exploit this issue to read arbitrary file on the server under <install-directory>/confluence/WEB-INF directory, which may contain configuration files used for integrating with other services, which could potentially leak credentials or other sensitive information such as LDAP credentials. The LDAP credential will be potentially leaked only if the Confluence server is configured to use LDAP as user repository. All versions of Confluence Server from 6.1.0 before 6.6.16 (the fixed version for 6.6.x), from 6.7.0 before 6.13.7 (the fixed version for 6.13.x), and from 6.14.0 before 6.15.8 (the fixed version for 6.15.x) are affected by this vulnerability.
Various exposed resources of the ViewLogging class in Jira before version 7.13.6, from version 8.0.0 before version 8.2.3, and from version 8.3.0 before version 8.3.2 allow remote attackers to modify various settings via Cross-site request forgery (CSRF).
The ViewSystemInfo class doGarbageCollection method in Jira before version 7.13.6, from version 8.0.0 before version 8.2.3, and from version 8.3.0 before version 8.3.2 allows remote attackers to trigger garbage collection via a Cross-site request forgery (CSRF) vulnerability.
