  Cisco Webex Meetings contained a cross-site scripting (XSS) vulnerability in its web interface that could allow an attacker to inject malicious scripts if a user clicked a crafted link. The vulnerability resulted from weak input validation. Cisco has already patched the service, and users do not need to take action—the fix has been deployed automatically.
