To prevent clickjacking, Jira adds the X-Frame-Options and Content-Security-Policy security headers to each HTTP response. The headers block the content from being embedded in iframes, which might also affect pages that you want to be displayed in this way. If you don't like this change, you can create a list of paths to be excluded from this protection or disable the security headers.

Security headers

Jira 7.6-8.15

The following headers have been introduced with Jira 7.6. You can read the original bug report here: JRASERVER-25143 - Getting issue details... STATUS

Jira 8.16 以降

In Jira 8.16 and later, the following header is introduced for security purposes: Content-Security-Policy: sandbox.

The sandbox directive enables a sandbox for a requested resource that is similar to the <iframe> sandbox attribute. It applies restrictions to an object's actions including preventing pop-ups, executing plugins and scripts, and enforcing a same-origin policy.

By default, the sandbox policy is enabled and applied:

• To all content types except for text/html, application/javascript, and text/javascript. These can’t be sandboxed.

• When the content-disposition header is set to attachment.

The default parameters can be tweaked by changing the following properties.

To modify the default properties:

1. Go to Administration > System > General configuration and select Advanced Settings.
   
2. Edit the values of the properties.
   

Additionally, we’ve added new properties that allow for configuring what clauses will be sent to what browsers and what paths should have such differentiation. This prevents failures when audio or video attachments are playing in some browsers.

Check the new properties.

Excluding paths

To create a list of paths excluded from the protection, use the com.atlassian.jira.clickjacking.protection.exclude system property and separate the paths with a comma. For example:

-Dcom.atlassian.jira.clickjacking.protection.exclude=/rest/my-plugin/1.0/dashboard,/rest/collectors/1.0/template/form/

For more info on how to apply this, see Setting properties and options.

Determining which paths to exclude

The easiest option is to examine the access logs from Jira. For example, if you have a report in Jira and want to display it in Confluence:

1. Add an iframe with the Jira report into Confluence and reload the page. In this example, the iframe URL is used. The report will fail to load. You can see this in the screenshot.

   http://localhost:8080/jira/secure/RapidBoard.jspa?rapidView=1&projectKey=SA&view=reporting&chart=cumulativeFlowDiagram&swimlane=1&column=4&column=5&column=6

   

2. Confluence will attempt to make several requests to Jira for the information needed to display the report. Due to the security headers, the report will fail to load.

3. Check Jira's access logs to see what URI endpoints were requested by Confluence. These are the paths you want to exclude. In this example, corresponding traces in the access logs are the following:

   0:0:0:0:0:0:0:1 i639x1086x1 admin [19/Aug/2022:10:39:44 +0200] "GET http://localhost:8080/jira/secure/RapidBoard.jspa HTTP/1.1" - - - "http://localhost:8090/" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/104.0.0.0 Safari/537.36" "1jv33ya"
   0:0:0:0:0:0:0:1 o639x1086x1 admin [19/Aug/2022:10:39:44 +0200] "GET http://localhost:8080/jira/secure/RapidBoard.jspa HTTP/1.1" 200 8698 0.0260 "http://localhost:8090/" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/104.0.0.0 Safari/537.36" "1jv33ya"

4. Add the endpoint from the access logs to the system property. Learn more in Setting properties and options.

   JVM_SUPPORT_RECOMMENDED_ARGS="-Dcom.atlassian.jira.clickjacking.protection.exclude=/secure/RapidBoard.jspa"

5. Restart Jira and attempt to load the iframe in Confluence. It will successfully display now.
   

Excluding paths in plugins

Jira 7.7 or later.

If you develop plugins for Jira and use iframes on purpose, you can also exclude paths on a Jira instance that uses your plugin.

To do this, add the paths to be excluded by adding the following code to the atlassian-plugin.xml file.

<clickjacking-http-headers-excluded-paths key=“some-unique-key-for-this-module”>

   <path>/plugins/servlet/reference-servlet-with-filter</path>

   <path>/plugins/servlet/other-servlet</path>

</clickjacking-http-headers-excluded-paths>

For more info, see this Java document.

Disabling security headers

To disable the protection, set the system com.atlassian.jira.clickjacking.protection.disabled property to true.

Steps to disable security header

1. From <jira-install>/bin, open setenv.bat (for Windows) or setenv.sh (for Linux).
2. Find the section set JVM_SUPPORT_RECOMMENDED_ARGS=.
3. Add the following code into to the section -Dcom.atlassian.jira.clickjacking.protection.disabled=true.

   1. The full argument should look as follows:

      set JVM_SUPPORT_RECOMMENDED_ARGS="-Dcom.atlassian.jira.clickjacking.protection.disabled=true"

4. Restart Jira to load the new argument.

For more information on how to apply this, see Setting properties and options.

Disabling Content-Security-Policy: sandbox

To turn off Content-Security-Policy: sandbox completely, set the feature flag jira.security.csp.sandbox.disabled.
