Overview

The Event Tickets with Ticket Scanner plugin for WordPress contains a Stored Cross-Site Scripting vulnerability (CVE-2024-9866) affecting all versions up to and including 2.4.4. The vulnerability was discovered and reported by Wordfence, with the initial disclosure made on December 6, 2024 (NVD).

Technical details

The vulnerability stems from insufficient input sanitization and output escaping in the 'data' parameters, combined with missing authorization on the ticket management functionality. The severity is rated as MEDIUM with a CVSS v3.1 base score of 5.4 (Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N). The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation) (NVD).

Impact

When exploited, this vulnerability allows authenticated attackers with subscriber-level access or higher to inject arbitrary web scripts into pages. These malicious scripts will execute whenever a user accesses the compromised page (NVD).

Mitigation and workarounds

The vulnerability has been addressed in two phases: the missing authorization aspect was patched in version 2.4.1, while the Cross-Site Scripting vulnerability was fully patched in version 2.4.4. Users are advised to update to version 2.4.4 or later to protect against this vulnerability (NVD).
