CVE-2026-17059 (GCVE-0-2026-17059)

Vulnerability from cvelistv5 – Published: 2026-07-24 14:06 – Updated: 2026-09-16 18:34

Title
Keycloak-services: keycloak-services: information disclosure via role-users endpoint bypasses per-user view filter
Summary
A flaw was found in the role-users endpoint of the keycloak-services library, which is the core component of the Keycloak identity and access management solution. The issue occurs because the system fails to check if an administrator has permission to view individual users when listing members of a role. This allows a restricted administrator to see private information, such as names and email addresses, for users they should not be able to access.

CVE-2026-16797 (GCVE-0-2026-16797)

Title
ShopLentor <= 3.4.5 - Insecure Direct Object Reference to Authenticated (Contributor+) Sensitive Information Exposure via 'optionSection' Parameter
Summary
The ShopLentor – All-in-One WooCommerce Growth & Store Enhancement Plugin plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.4.5 via the 'optionSection' parameter due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with contributor-level access and above, to read arbitrary wp_options rows — including internal plugin news feed data, WooCommerce block pattern transients, and third-party configuration records — whose values are stored as arrays-of-arrays containing 'title' keys, enabling cross-plugin data leakage.
Severity

Mitigation
Architecture and Design

For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.

Mitigation
Architecture and Design Implementation

Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.

Mitigation
Architecture and Design

Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
