CVE-2024-12403: 
WordPress vulnerability analysis and mitigation

The Image Gallery – Responsive Photo Gallery plugin for WordPress contains a Reflected Cross-Site Scripting vulnerability (CVE-2024-12403) that affects all versions up to and including 1.0.5. The vulnerability was discovered and disclosed on January 14, 2025, and is tracked with a CVSS v3.1 base score of 6.1 (Medium) (NVD, Wordfence).

The vulnerability exists due to insufficient input sanitization and output escaping of the 'awsmgallery' parameter. This security flaw is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation). The vulnerability has received a CVSS v3.1 score of 6.1, indicating medium severity, with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N (NVD).

The vulnerability allows unauthenticated attackers to inject arbitrary web scripts that execute when users perform specific actions, such as clicking on a malicious link. This can lead to potential compromise of user data and interactions within the affected WordPress installations (NVD).

Users should update to a version newer than 1.0.5 when available. Until then, website administrators should consider implementing additional security controls such as Web Application Firewalls (WAF) to help mitigate potential exploitation attempts (Wordfence).
