Missing Authorization vulnerability in everestthemes Everest Backup everest-backup allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Everest Backup: from n/a through <= 2.3.8.
AnalysisAI
An unauthenticated attacker can exploit missing authorization checks in the Everest Backup WordPress plugin (<=2.3.8) to trigger resource-intensive backup operations without any privileges, causing a low impact on server availability. No active exploitation or public proof-of-concept is known, and the EPSS score is very low (0.06%).
Technical ContextAI
The vulnerability is a Missing Authorization (CWE-862) flaw in a WordPress backup plugin written in PHP. The affected product, identified by the CPE string 'everestthemes Everest Backup', fails to properly enforce access controls on a backup-related endpoint. This means the application does not verify whether the requesting user has the necessary permissions to invoke the backup functionality. The CVSS vector indicates a network-accessible (AV:N) endpoint with low attack complexity (AC:L), no privilege requirements (PR:N), and no user interaction (UI:N), suggesting the endpoint is directly callable by anyone who can reach the WordPress site.
Affected ProductsAI
The vulnerability affects the Everest Backup WordPress plugin from any earlier version up to and including 2.3.8. The official advisory is available at the Patchstack database: https://patchstack.com/database/Wordpress/Plugin/everest-backup/vulnerability/wordpress-everest-backup-plugin-2-3-8-broken-access-control-vulnerability?_s_id=cve.
RemediationAI
Upgrade the Everest Backup plugin to a version higher than 2.3.8 as soon as a patched release is available. If an immediate update is not possible, consider temporarily disabling the plugin until the fix is applied, though this will remove backup functionality. Refer to the vendor's advisory linked in the Patchstack reference for the exact fixed version.
