Security Vulnerabilities
CVE-2026-76504
A vulnerability in the API session-based authentication management of Cisco Catalyst SD-WAN Manager could allow an unauthenticated, remote attacker to access an affected system with privileges of the admin user.
This vulnerability is due to improper handling of URI encoding in an HTTP request, which allows the request to bypass an authentication rule that is intended to restrict access to a specific API endpoint. An attacker could exploit this vulnerability by sending a crafted HTTP request to the API of the affected system. A successful exploit could allow the attacker to bypass authentication and gain access to the API as the admin user.

Apache WSS4J accepted attacker-controlled derived-key lengths and offsets without adequate bounds. This could permit cryptographically weak keys or excessive CPU and memory consumption when processing crafted WS-Security messages. The fixes enforce a minimum key length of 16 bytes, a maximum length of 512 bytes, and a maximum offset of 4096 bytes.
Users are recommended to upgrade to versions 4.0.2 or 3.0.6 or 2.4.4, which fix this issue.

A flaw was found in Moodle. User list filters do not properly enforce visibility restrictions on user profile fields. An authorized user with manager privileges can filter user lists using profile attributes they are not permitted to view directly, resulting in unauthorized information disclosure by inferring hidden user data.

A flaw was found in Moodle. The XML grade import feature lacks proper Cross-Site Request Forgery (CSRF) token validation. By tricking an authenticated user with grade management permissions into visiting a malicious webpage, an attacker can trigger unauthorized requests on the victim's behalf. This flaw allows a remote attacker to set or overwrite student grades without authorization.

A flaw was found in Moodle. The manual enrolment management page did not properly check whether the manual enrolment plugin was disabled, allowing users with enrolment permissions to access the page directly by navigating to its URL. Consequently, an authorized user could manage manual enrolments even after an administrator disabled the feature in the user interface.
