## Overview

Operation on a Resource after Expiration or Termination (CWE-672) in Kibana can lead to unauthorized information disclosure. A logic error in how expiration timestamps were validated allowed a time-bounded access token to remain usable beyond its intended validity window, enabling an unauthenticated actor in possession of the token to retrieve the associated content after expiration.

## Affected

- `kibana >= 8.0.0, < 8.19.16`
- `kibana >= 9.0.0, < 9.3.5`

## Remediation

Upgrade past the affected range:

- `kibana 9.3.5`
