**Name of the Vulnerable Software and Affected Versions**
macOS Sonoma versions prior to 14.2.1
**Description**
A session rendering issue was addressed with improved session tracking. This issue may cause a user who shares their screen to unintentionally share the incorrect content. The problem is related to the WindowServer component of the macOS operating system and is associated with a lack of protection for service data, which could allow a remote attacker to gain unauthorized access to the user's screen.
**Recommendations**
For macOS Sonoma versions prior to 14.2.1, update to macOS Sonoma 14.2.1 to fix the session rendering issue.
As a temporary workaround, consider avoiding screen sharing until the issue is resolved.
Restrict access to sensitive content when using screen sharing features to minimize the risk of exploitation.
