CVE-2022-26135 Full Read SSRF in Jira Server


A full-read server-side request forgery exists in Mobile Plugin for Jira, which
is bundled with Jira and Jira Service Management. It is exploitable by any
authenticated user (including a user who joined via the sign-up feature). It
specifically affects the batch HTTP endpoint used in Mobile Plugin for Jira. It
is possible to control the HTTP method and location of the intended URL through
the method parameter in the body of the vulnerable endpoint.

All versions of Jira and Jira Service Management prior to the fixed version
listed above are affected by this vulnerability. These issues can be tracked

o JRASERVER-73863 – Getting issue details… STATUS
o JSDSERVER-11840 – Getting issue details… STATUS

This does not affect the other System app named Jira Mobile.


Atlassian rates the severity level of this vulnerability as high, according to
the scale published in our Atlassian severity levels. The scale allows us to
rank the severity as critical, high, medium, or low.

Depending on the environment the Jira instance is deployed in, the impact of
this bug varies. For example, when deployed in AWS, it could leak sensitive

This is our assessment and you should evaluate its applicability to your own IT


We would like to acknowledge Shubham Shah and Dylan Pindur of Assetnote for
finding this vulnerability.


To address this issue, we have released:

o Jira Core Server, Jira Software Server, and Jira Software Data Center
o 8.13.22
o 8.20.10
o 8.22.4
o 9.0.0
o Jira Service Management Server and Data Center versions:
o 4.13.22
o 4.20.10
o 4.22.4
o 5.0.0

You can download the latest versions from the download pages for Jira Core,
Jira Software, or Jira Service Management.

Please note, these are the first versions that include the fix for
CVE-2022-26135. More current bug fix releases are available for the releases
listed above. Atlassian recommends upgrading to the most current bug fix


Installing a fixed version of Jira or Jira Service Management is the surest way
to remediate CVE-2022-26135. If you are unable to immediately upgrade Jira or
Jira Service Management, then as a temporary workaround, you can manually
upgrade Mobile Plugin for Jira Data Center and Server
( to the versions specified in this
section (or disable the plugin).

The following versions of the Mobile Plugin for Jira app contain a fix for this

o 3.1.5 (only compatible with Jira 8.13.x and JSM 4.13.x)
o 3.2.15 (only compatible with Jira 8.20.x – 8.22.x, only compatible with JSM
4.20.x – 4.22.x)

If you’re either on Jira 8.13.x or JSM 4.13.x and have previously upgraded
beyond the default app version of 3.1.x, upgrading to 3.1.5 will effectively
roll back any bug-fixes and features introduced in later versions, including
JSM support.

How to upgrade the app

Scenario A: User-installed apps

If you find the “Mobile Plugin for Jira” app located in the User-installed apps
section, you can just click Update to get the latest version.

Scenario B: System apps

If you find the “Mobile Plugin for Jira” app located in the System apps
section, follow these instructions to manually update the app (no restart

1. Download a fixed version of the app (you’ll save this as a JAR file) from
the Atlassian Marketplace that is compatible with your Jira version
2. During a maintenance window:
1. Navigate to Admin > Manage Apps
2. Select Upload app
3. Select the JAR file you downloaded in Step 1
3. After the install, the new version will be displayed as a user-installed
app instead of a system app.

o The previous JAR file can remain in the directory /
atlassian-jira/WEB-INF/atlassian-bundled-plugins without further action.
