CVE-2026-75835

4.3 · MEDIUM
Published Aug 18, 2026 CWE-862 EPSS 0.22% (13th pctl)

Overview

CVE-2026-75835 is a medium-severity vulnerability. It was published on August 18, 2026 and has a CVSS 3.1 base score of 4.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.3, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical Description

Grav API plugin (getgrav/grav-plugin-api) before 1.0.14 contains a missing authorization vulnerability in userPassesAuthorize() (AbstractApiController.php). The function fails to consult the calling request's API key scopes, relying instead on the account's raw super-admin flag and ACL grants. As a result, an authenticated attacker holding a scoped API key minted on a privileged account can bypass their declared scope restrictions to access authorize-gated UI metadata and item definitions (sidebar/menubar/widget items and users-list columns/row-actions/filter-tabs) that their key scope should deny, resulting in information disclosure.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
