CVE-2026-12258
CriticalCVSS 9.2Summary
Inadequate access control exists in Hiperdino's REST v1.0 API. The public endpoint 'customer/check' allows an authenticated attacker to enter a telephone number or email address; when the value belongs to a registered customer, the service returns the associated information (email address and telephone number). No authentication is required beyond a static bearer token, and there is no rate limiting or generic error handling.
Risk Assessment
A remote attacker can enumerate users' contact details, constituting an information disclosure vulnerability. This requires obtaining a valid static bearer token.
Recommendation
Implement proper access control on the 'customer/check' endpoint, add rate limiting and generic error handling. Replace the static bearer token with a strong authentication mechanism.

The Multi Uploader for Gravity Forms plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to and including 1.1.9 via the move_file function. This is due to insufficient file type validation during chunked upload handling. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.

djust prior to version 1.0.7 has a vulnerability in the WebSocket transport that bypasses standard Django authorization mechanisms (such as LoginRequiredMixin, PermissionRequiredMixin, etc.) and the staff gate in the admin extension. Mount authorization is done via check_view_auth, not the View.dispatch() chain, allowing anonymous or under-privileged clients to open a WebSocket and dispatch view handlers, including admin ones.

UVdesk Community Skeleton through 1.1.8 fails to authenticate or validate installation state on wizard endpoints in ConfigureHelpdesk controller actions. Unauthenticated attackers can repoint the database and create super administrator accounts by submitting crafted requests to wizard endpoints, gaining full control of the instance.

Feast through 0.66.0 fails to verify JWT token signatures before establishing user identity, allowing attackers to bypass all role-based access control by presenting an unverified token with a hardcoded claim value. Attackers can obtain trusted internal identity and gain unchecked read and write access to all entities, feature views, data sources, and permission policies on the server.

A vulnerability in the API of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to bypass authentication. This is due to insufficient authentication control on an API endpoint. An attacker could send a crafted request to gain unauthorized access to the device by bypassing the web-based management interface.

Marten from version 7.0.0 until 9.13.0 has a vulnerability involving interpolation of runtime, potentially attacker-controlled strings into single-quoted SQL literals without escaping or parameterization in several LINQ and tenant-management paths. The primary confirmed vector is a dictionary indexer key used by Where filters. This could enable filter or multi-tenant authorization bypass and blind data exfiltration, and in some configurations data modification.

Vulnerabilities in Cisco Secure Adaptive Security Appliance Software, Cisco Secure Firewall Threat Defense Software, and Cisco Secure Firewall Management Center Software are related to improper access control issues (CWE-284). They were discovered during an internal security review and have been addressed in a software hardening release.
- CVE-2026-20284Critical
A vulnerability in the SXP REST API of Cisco ISE could allow an authenticated, remote attacker to conduct SQL injection attacks. This is due to insufficient validation of user-supplied input in REST API calls. A successful exploit could allow the attacker to view or modify data on the underlying database, and in single-node deployments could cause a DoS condition.
- CVE-2026-92808Critical
A server-side request forgery (SSRF) vulnerability exists in the UnifiedLogin service of Altium Enterprise Server. An unauthenticated network attacker can cause the server to issue outbound HTTP requests to a destination of the attacker's choosing, including internal services reachable only from the server. One such internal service exposes configuration and credential material without authentication, relying on local origin, which is satisfied by forged requests.

Original NVD description (English source)
Inadequate access control in Hiperdino’s REST v1.0 API. The public endpoint ‘customer/check’ could allow an authenticated attacker to enter a telephone number or an email address. When the value entered belongs to a registered customer, the service returns the associated information (email address and telephone number). No authentication is required beyond a static bearer token, and there is no rate limiting or generic error handling. Successful exploitation of this vulnerability could allow a remote attacker to enumerate a user’s contact details, although this would require obtaining a valid static bearer token, constituting an information disclosure vulnerability.
