Okta Access Gateway: Improper Neutralization of Directives in Dynamically Evaluated Code

CVE-2026-78550 is a high-severity improper neutralization of directives in dynamically evaluated code vulnerability in Okta Access Gateway from Okta, with a CVSS 3.1 base score of 7.2 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. The record lists version 2026.9.1 as the first without the flaw, so updating Okta Access Gateway to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.38% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

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.

The underlying weakness: Improper Neutralization of Directives in Dynamically Evaluated Code

The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes code syntax before using the input in a dynamic evaluation call (e.g. eval).

How developers prevent this class of flaw

  • If possible, refactor your code so that it does not need to use eval() at all.
  • For Python programs, it is frequently encouraged to use the ast.literal_eval() function instead of eval, since it is intentionally designed to avoid executing code. However, an adversary could still cause excessive memory or stack consumption via deeply nested structures, so the python documentation discourages use of ast.literal_eval() on untrusted data.
