Gartner analyst Peter Firstbrook noted in an email that, since Cisco has applied the patch to the cloud service, this is more of a configuration change. But that doesn’t minimize the possible damage. “While we are not aware of exploits using this vulnerability, users can lose SSO access to Webex without this change,” he said.
“This does illustrate a bigger trend that identity and access management is the corporate perimeter,” he added, “and the majority of attacks include an identity and access management component. CISOs must increase their focus on IAM hygiene, particularly as agentic computing is accelerating.”
Identity and access management is, of course, the keystone of cybersecurity. As Crowdstrike observed in its 2026 Global Threat Report, abuse of valid accounts accounted for 35% of cloud incidents it investigated last year, “reinforcing that identity has become central to intrusion.” Single sign-on allows a user to authenticate to multiple applications through one set of credentials. It’s efficient, and, of more importance to a CSO, strengthens security.
