CVE-2026-78550

Okta Access Gateway does not neutralize shell metacharacters in SNMP configuration values before a privileged script uses them to construct OS commands. An authenticated local user with access to the management interface can supply crafted values, resulting in the execution of arbitrary OS commands with root privileges.

Okta Access Gateway improperly handles input sanitization and regular expression evaluation within its Protected Rule authorization check, resulting in an authorization bypass when an administrator has explicitly configured a Protected Rule policy on one or more application resources.

The Okta Access Gateway does not sanitize dashboard label values before writing them into generated PHP configuration files. The generated file is automatically included during authentication requests, resulting in execution with the privileges of the web server process.

The Okta Access Gateway backup restore function does not validate the filename embedded in an encrypted backup payload. This results in writing file contents to unintended locations on the appliance filesystem.

Okta Access Gateway does not sanitize SAML assertion values before interpolating them into database queries in the advanced mode datastore configuration. The unsanitized values are substituted directly into the query string prior to preparation, resulting in unintended SQL execution against the configured backend database.

The Okta Access Gateway Kerberos configuration handler does not validate file paths specified in event payloads before writing file contents. The path from the event payload is used directly as the write destination, resulting in files being written to unintended locations on the appliance filesystem.

The Okta Access Gateway does not sanitize SAML assertion attribute values before interpolating them into LDAP search filters in the LDAP datastore configuration. The raw values are substituted directly into the filter string and passed to the LDAP search operation, resulting in modification of the intended query logic.

The Okta Access Gateway includes an optional pass-through authentication source that accepts user identity from a client-supplied HTTP header without cryptographic validation. In architectures where this optional source is enabled without an upstream reverse proxy or firewall configured to sanitize and enforce client headers, an unauthenticated user can supply an arbitrary identity value to initiate a session.

Okta Access Gateway does not apply its Lua directive restriction to the application-level custom configuration field. The field is interpolated directly into the nginx server block without inspection, resulting in execution of injected directives.

The Okta Access Gateway does not sanitize the application label field before including it in the generated nginx configuration file. The unsanitized value is interpolated into an nginx server block directive, resulting in execution of injected directives.
