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.

GHSA-9gcg-w975-3rjh — Istio: AuthorizationPolicy serviceAccounts regex injection via unescaped dots

2026-10-07T09:49:39.416847+00:00

Affected: Go: istio.io/istio

### Impact 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 SA e.g. `cert-manager.io` also matches `cert-manager-io`, `cert-managerXio`, etc. A DENY rule targeting the same name fails to block those variants.

### Patches Fixes are available in 1.29.2, 1.28.6, and 1.27.9

### Workarounds None
