DescriptionCVE.org

The Eventin - Event Calendar, Event Registration, Tickets & Booking (AI Powered) plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 4.1.22 via the 'event_layout' parameter parameter. This makes it possible for authenticated attackers, with contributor-level access and above, to include and execute arbitrary .php files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where .php file types can be uploaded and included. The etn_manage_event capability is assigned to Contributors by default, meaning any Contributor-level user can set the malicious event_layout value via the REST API without any additional configuration.

AnalysisAI

Local File Inclusion in the Eventin WordPress event management plugin (versions ≤4.1.22) allows authenticated contributors to include and execute arbitrary PHP files on the server via the unsanitized 'event_layout' parameter, achieving full remote code execution. The etn_manage_event capability is assigned to WordPress Contributors by default, meaning any registered Contributor can set the malicious parameter value through the REST API without any site-specific configuration change. …

Vulnerability AssessmentAI

Exploitation Requires a WordPress user account at Contributor level or above - the etn_manage_event capability is assigned to Contributors by default so no special role configuration is needed. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 7.5 score (AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H) reflects a meaningful but constrained risk: the high complexity rating captures the requirement that a PHP file must already exist at an attacker-reachable path on the server before inclusion can be triggered. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Update the Eventin plugin to the version immediately following 4.1.22 (expected 4.1.23 or later) via the WordPress dashboard or the plugin repository; verify the patch corresponds to changeset 3668637 at https://plugins.trac.wordpress.org/changeset?reponame=&old=3668637%40wp-event-solution&new=3668637%40wp-event-solution. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Audit all WordPress user accounts to identify those with Contributor or higher roles and determine which sites run Eventin plugin versions 4.1.22 or earlier. …
