WordPress vulnerability analysis and mitigation

The Newpost Catch plugin for WordPress contains a Stored Cross-Site Scripting vulnerability (CVE-2025-1406) discovered on February 20, 2025. The vulnerability affects all versions up to and including 1.3.19 of the plugin. This security issue is present in the plugin's npc shortcode functionality (NVD).

The vulnerability stems from insufficient input sanitization and output escaping on user-supplied attributes in the npc shortcode. The issue has been assigned a CVSS v3.1 base score of 5.4 (Medium) by NIST with a vector string of CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N. Wordfence has assessed it with a slightly higher CVSS score of 6.4 (Medium). The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation) (NVD).

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

The vulnerability requires an authenticated user with at least contributor-level privileges to exploit. The attack complexity is considered low, requiring network access and user interaction for successful exploitation (NVD).

Users of the Newpost Catch plugin should update to a version newer than 1.3.19 if available. The plugin is actively maintained, as evidenced by its current version 1.3.22 and compatibility with WordPress 6.7.2 (WordPress Plugin).
