CVE-2026-78550: Improper Input Handling in Okta Access Gateway Management Console Exception Handler
The Okta Access Gateway management console passes user-supplied input to eval() without sanitization during an authenticated administrator SSH session. As a result, the unsanitized input is executed directly, leading to code execution with the privileges of the management console.

Frequently Asked Questions
Who is exposed to this issue?
The affected component is the Okta Access Gateway management console. Exploitation requires an authenticated administrator SSH session, so exposure is limited to environments where an attacker can obtain or use administrator-level SSH access to that console.
What does an attacker need to exploit it?
An attacker needs administrator authentication for an SSH session to the management console and must be able to supply input that reaches the exception handler. The attack complexity is rated high, and no user interaction is required.
What is the potential impact after successful exploitation?
Unsanitized user input is passed to eval() and executed with the privileges of the management console. Successful exploitation can result in code execution and high impact to confidentiality, integrity, and availability.
