DescriptionCVE.org

Missing Authorization vulnerability in avalex avalex avalex allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects avalex: from n/a through <= 3.1.3.

AnalysisAI

Improper access control in Avalex versions up to 3.1.3 allows unauthenticated remote attackers to modify data or cause service disruptions due to incorrectly configured security levels. The vulnerability requires no user interaction and can be exploited over the network, affecting the integrity and availability of the affected system.

Technical ContextAI

Avalex is a WordPress plugin (identified via CPE cpe:2.3:a:avalex:avalex:*:*:*:*:*:*:*:*) that manages access control and authentication within WordPress environments. The vulnerability stems from CWE-862 (Missing Authorization), which occurs when software fails to properly enforce access control checks before allowing users to perform sensitive operations. In this case, the plugin's authorization logic incorrectly configures security levels, allowing the access control enforcement mechanism to be bypassed entirely. This represents a fundamental failure in the authorization layer rather than an authentication bypass, meaning authenticated or unauthenticated users may gain unintended permissions by exploiting improperly validated access control rules.

RemediationAI

Upgrade the Avalex WordPress plugin to a version after 3.1.3 immediately, as the vulnerability has been patched in subsequent releases. Verify the updated version through the official WordPress plugin repository or the vendor's advisory at Patchstack (https://patchstack.com/database/Wordpress/Plugin/avalex/vulnerability/wordpress-avalex-plugin-3-1-3-broken-access-control-vulnerability). Until patching is completed, implement the following interim controls: review and audit all user roles and capabilities within Avalex to ensure access control rules are correctly configured, disable or deactivate the Avalex plugin if it is not actively in use, restrict access to Avalex administration panels to trusted IP addresses only, and monitor server logs for unauthorized access attempts or privilege escalation activities. After patching, conduct a full access control audit to identify any unauthorized actions that may have been performed during the vulnerability window.
