CVE-2017-13997
CriticalSummary
A Missing Authentication for Critical Function issue was discovered in InduSoft Web Studio v8.0 SP2 and prior, and InTouch Machine Edition v8.0 SP2 and prior. A remote malicious entity could bypass server authentication and trigger the execution of an arbitrary command.
Risk Assessment
An attacker could gain access to the server with high privileges, potentially leading to a complete compromise of the system. This poses a serious security threat to the organization.
Recommendation
It is recommended to update InduSoft Web Studio and InTouch Machine Edition to the latest version to mitigate this vulnerability. Additionally, appropriate authentication mechanisms for critical functions should be implemented.

The Events Calendar plugin for WordPress in all versions up to and including 6.17.3 is vulnerable to Remote Code Execution via the parse_array function. Insufficient validation of the widget 'classes' map allows a plain-array payload to bypass the is_safe_widget_instance() object check and reach the callable-invocation sink in Element_Classes::parse_array(). This enables unauthenticated attackers to execute code on the server, provided comments are enabled on tribe_events posts and at least one comment containing a crafted wp:legacy-widget block has been submitted.
- CVE-2026-78006Critical
The Events Calendar plugin for WordPress in all versions up to and including 6.17.4 is vulnerable to Remote Code Execution via the is_safe_widget_instance function. Insufficient protection in is_safe_widget_instance can be bypassed because PHP fires magic methods during its pre-parse, combined with enable_rendering_widget_copied() forging a valid wp_hash integrity attribute before unserialize() is reached. This enables unauthenticated attackers to execute code on the server, as the plugin's V2 single-event template runs do_blocks() over buffered comment HTML and WordPress returns a moderation-hash URL allowing an unauthenticated commenter to immediately view their own pending comment.

GitLab EE versions from 18.3 before 19.1.8, 19.2 before 19.2.6, and 19.3 before 19.3.2 contain a vulnerability that, under certain conditions, allows an authenticated user with Duo Chat access to obtain Advanced Search instance configurations and sensitive credentials. Exploitation uses a specially crafted GraphQL subscription argument to bypass serialization and perform server object lookup.

GitLab CE/EE versions from 18.7 before 19.1.8, 19.2 before 19.2.6, and 19.3 before 19.3.2 contain a vulnerability in the repository commits API caused by improper path confinement and missing authentication enforcement. Under certain conditions, an unauthenticated user could read arbitrary files from the GitLab server.
- CVE-2026-90456Critical
An example environment-configuration file for a bundled inventory-management component ships with a fixed, publicly-known administrative password. A deployment that copies this example file into active configuration without running the setup routine that regenerates credentials will expose that component's administrative interface to anyone aware of the default value.

GetSimple CMS (v3.4.0a and below) and GetSimple CMS CE (v3.3.22 and below) contain a logic flaw allowing unauthenticated attackers to create a new administrator account. The automated control that deletes admin/setup.php after installation is neutralized by a self-exclusion bug, leaving the setup script accessible. As of publication, no patched versions are available.

The WS-Security (wsse:UsernameToken) verification routine in the Sofia IPC daemon in Xiongmai IP Camera XM530 firmware HMT.CM2005-v220608.1837 and earlier has an improper authentication vulnerability. A remote attacker can bypass authentication and execute privileged ONVIF actions (PTZ control, stream URL retrieval, system reboot) via a crafted SOAP request supplying the admin username with any arbitrary password when the account's stored password is empty.

In Authorizer prior to version 2.2.1, the /authorize endpoint accepts any redirect_uri without validating it against AllowedOrigins. With response_type=token or response_type=id_token, the server appends access_token, id_token, and refresh_token as query parameters and issues a 302 redirect to the attacker-supplied URL. An unauthenticated attacker can obtain the client_id from the public /graphql endpoint.
Original NVD description (English source)
A Missing Authentication for Critical Function issue was discovered in Schneider Electric InduSoft Web Studio v8.0 SP2 or prior, and InTouch Machine Edition v8.0 SP2 or prior. InduSoft Web Studio provides the capability for an HMI client to trigger script execution on the server for the purposes of performing customized calculations or actions. A remote malicious entity could bypass the server authentication and trigger the execution of an arbitrary command. The command is executed under high privileges and could lead to a complete compromise of the server.
