**Name of the Vulnerable Software and Affected Versions** Zammad versions prior to 6.3.0 **Description** An issue was discovered where the Zammad Upload Cache uses insecure, partially guessable FormIDs to identify content. This could allow an attacker to brute force these IDs and upload malicious content to article drafts they do not have access to. **Recommendations** For versions prior to 6.3.0, update to version 6.3.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the Zammad Upload Cache to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** WooCommerce Multiple Customer Addresses & Shipping WordPress plugin versions prior to 21.7 **Description** The issue allows any authenticated user to add, update, duplicate, delete, and retrieve addresses of other users, due to insufficient validation of user privileges. This affects users with low privileges, such as subscribers. **Recommendations** For versions prior to 21.7, update to version 21.7 or later to resolve the issue. As a temporary workaround, consider restricting access to the address management functionality to high-privilege users until the update is applied.
