Cisco tells Webex users to patch critical security flaws immediately


Cisco has pushed a new patch to address four critical-severity vulnerabilities plaguing its cloud-based Webex Services platform – and has also warned Wi-Fi access points users of a bug in certain versions of IOS XE that could result in a device bootloop.

It was found vulnerable to four flaws: CVE-2026-20184 (9.8/10 – a vulnerability in the integration of single sign-on (SSO)), CVE-2026-20147 (9.9/10 – a remote code execution bug in Cisco ISE and Cisco ISE-PIC), CVE-2026-20180, and CVE-2026-20186 (9.9/10 arbitrary code execution flaws in Cisco Identity Services Engine).
