WordPress vulnerability analysis and mitigation

The Print-O-Matic WordPress plugin (versions up to 2.1.10) contains a Stored Cross-Site Scripting vulnerability (CVE-2024-3671) discovered on May 22, 2024. The vulnerability exists in the plugin's 'print-me' shortcode due to insufficient input sanitization and output escaping on user-supplied attributes such as 'tag' (NVD).

The vulnerability stems from inadequate input sanitization and output escaping mechanisms in the plugin's 'print-me' shortcode, particularly affecting user-supplied attributes like 'tag'. The issue has been assigned a CVSS v3.1 Base Score of 6.4 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N (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 (NVD).

The vulnerability requires an authenticated user with at least contributor-level privileges to exploit. The plugin has been closed as of June 14, 2024, due to this security issue (WordPress Plugin).

As the plugin has been closed due to this security issue, the recommended mitigation is to immediately remove the Print-O-Matic plugin from WordPress installations and seek alternative solutions (WordPress Plugin).
