The vulnerability exists due to errors in processing input data. It is estimated that over 224,962 potentially vulnerable instances of Confluence Data Center and Confluence Server are exposed to the internet, with the majority located in the USA, Japan, France, and Germany. The vulnerability can be exploited by an authenticated threat actor to execute arbitrary code, and the compromised system can be used as a pivot point for further attacks within the network. **Recommendations** For Confluence Data Center versions 8.9.0 and earlier, upgrade to version 8.9.1.

**Name of the Vulnerable Software and Affected Versions** Jira Service Management Server and Data Center versions 5.3.0 through 5.5.0 **Description** An authentication issue in Jira Service Management Server and Data Center allows an attacker to impersonate another user and gain access to a Jira Service Management instance under certain circumstances. With write access to a User Directory and outgoing email enabled on a Jira Service Management instance, an attacker could gain access to signup tokens sent to users with accounts that have never been logged into. Access to these tokens can be obtained in two cases: * If the attacker is included on Jira issues or requests with these users, * If the attacker is forwarded or otherwise gains access to emails containing a “View Request” link from these users. Bot accounts are particularly susceptible to this scenario. On instances with single sign-on, external customer accounts can be affected in projects where anyone can create their own account. **Recommendations** For versions 5.3.0 through 5.3.2, update to version 5.3.3 or later. For version 5.4.0 and 5.4.1, update to version 5.4.2 or later. For version 5.5.0, update to version 5.5.1 or later. As a temporary workaround, consider restricting access to the User Directory and disabling outgoing email to minimize the risk of exploitation.
