CVE-2026-78635 (GCVE-0-2026-78635)

Vulnerability from cvelistv5 – Published: 2026-09-08 20:14 – Updated: 2026-09-10 14:38

Title

Improper Input Validation in the Okta Privileged Access SSH Client URL Handler Argument

Summary

The Okta Privileged Access client URL handler does not insert an option terminator before appending the target value to the command-line arguments. When a scaleft:// protocol handler link contains a value beginning with a hyphen, the underlying CLI framework interprets it as a command-line flag, causing unintended modification of the SSH client's behavior.

Severity
