Atlassian has released fixes to resolve a critical security flaw in Jira Service Management Server and Data Center that could be abused by an attacker to pass off as another user and gain unauthorized access to susceptible instances.

The vulnerability is tracked as CVE-2023-22501 and has been described as a case of broken authentication with low attack complexity.

"An authentication vulnerability was discovered in Jira Service Management Server and Data Center which allows an attacker to impersonate another user and gain access to a Jira Service Management instance under certain circumstances," Atlassian said.

"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."

The Australian software services provider said the vulnerability was introduced in version 5.3.0 and impacts all subsequent versions 5.3.1, 5.3.2, 5.4.0, 5.4.1, and 5.5.0.

With flaws in Atlassian products becoming an alluring attack vector in recent months, it's crucial that users upgrade their installations to the latest versions to mitigate potential threats.
