Report: CVE-2026-39350 - Istio AuthorizationPolicy Incorrect Regex Matching of Dots in serviceAccounts Fi
CVE ID :CVE-2026-39350 Published : April 15, 2026, 11:16 p.m. | 1 hour, 29 minutes ago Description :Istio is an open platform to connect, manage, and secure microservices. In versions 1.25.0 through 1.27.8, 1.28.0 through 1.28.5, 1.29.0, and 1.29.1, the serviceAccounts and notServiceAccounts fields in AuthorizationPolicy incorrectly interpret dots (.) as a regular expression matcher. Because . is a valid character in a service account name, an AuthorizationPolicy ALLOW rule targeting a service account such as cert-manager.io also matches cert-manager-io, cert-managerXio, etc. A DENY rule targeting the same name fails to block those variants. Fixes are available in versions 1.29.2, 1.28.6, and 1.27.9. Severity: 5.4 | MEDIUM Visit the link for more details, such as CVSS details, affected products, timeline, and more...
