Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (2.23%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

In JetBrains YouTrack Confluence plugin versions before 1.8.1.3, it was possible to achieve Server Side Template Injection. The attacker could add an Issue macro to the page in Confluence, and use a combination of a valid id field and specially crafted code in the link-text-template field to execute code remotely.
