Description

Original: Researchers at the University of Cambridge reported a vulnerability affecting Jira Service Management Server / DC (and Insight Asset Management app) where special characters, known as Unicode bidirectional override characters, are not rendered or displayed in the affected applications. These special characters are typically not displayed by the browser or code editors but can affect the meaning of the source code when it is processed by a compiler or an interpreter. The issue is now fixed. *Affected versions:*  * *Jira Service Management Server and Data Center*  ** All versions before 4.13.13  ** All versions between 4.14.0 and 4.19.1 (inclusive)  *  ** All 4.20.x LTS versions before 4.20.1  * *Insight Asset Management* (Marketplace app for Jira Service Management)  ** All versions before 8.9.4 *Fixed versions:*  * *Jira Service Management Server and Data Center*  ** 4.13.13  ** 4.20.1  * *Insight Asset Management* (Marketplace app for Jira Service Management)  ** 8.9.4
