Security headers in JIRA
To prevent clickjacking, Jira adds the
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.
The following headers have been introduced with Jira 7.6. You can read the original bug report here: - JRASERVER-25143Getting issue details... STATUS
Jira 8.16 and later
In Jira 8.16 and later, the following header is introduced for security purposes:
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
When the content-disposition header is set to
The default parameters can be tweaked by changing the following properties.
Indicates the original media type of the resource
Indicates if the content will be displayed inline in the browser, on a web page, or as an attachment that can be downloaded
To modify the default properties:
- Go to Administration > System > General configuration and select Advanced Settings.
- 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.
You can’t see it in the user interface.
By default, paths that have differentiated clauses are
A Jira admin can specify additional paths only in the
It’s visible only to a System admin in Advanced settings in General configuration of the Jira instance.
The property allows for appending suffixes required by browsers. For example, Chrome needs
If any new bugs in browsers appear, the System admin can tweak this behavior for supported browsers.

The default value for this property is:
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:

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:
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.
- 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.
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/220.127.116.11 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/18.104.22.168 Safari/537.36" "1jv33ya"
Add the endpoint from the access logs to the system property. Learn more in Setting properties and options.
- 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
<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
Steps to disable security header
<jira-install>/bin, open setenv.bat (for Windows) or setenv.sh (for Linux).
- Find the section set JVM_SUPPORT_RECOMMENDED_ARGS=.
- Add the following code into to the section -Dcom.atlassian.jira.clickjacking.protection.disabled=true.
The full argument should look as follows:
- Restart Jira to load the new argument.
For more information on how to apply this, see Setting properties and options.
To turn off
Content-Security-Policy: sandbox completely, set the feature flag
