Deeper analysis

CVE-2025-23850 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the Mojo Under Construction WordPress plugin by mojowill. This issue affects the plugin from unknown initial versions through version 1.1.2 inclusive. The vulnerability was published on 2025-03-03.

The CVSS v3.1 base score is 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L), indicating network accessibility, low attack complexity, no privileges required, and user interaction needed, with changed scope and low impacts on confidentiality, integrity, and availability. Remote attackers can exploit it by tricking authenticated or unauthenticated users into interacting with malicious input, such as clicking a crafted link, leading to execution of arbitrary JavaScript in the victim's browser context.

The Patchstack advisory provides further details on the vulnerability in the WordPress Mojo Under Construction plugin version 1.1.2, including remediation guidance, accessible at https://patchstack.com/database/Wordpress/Plugin/mojo-under-construction/vulnerability/wordpress-mojo-under-construction-plugin-1-1-2-reflected-cross-site-scripting-xss-vulnerability?_s_id=cve.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-15 Information Output Filtering good match
prevent

Information Output Filtering directly prevents reflected XSS by encoding or filtering user input reflected in web page generation to block JavaScript execution.

SI-10 Information Input Validation good match
prevent

Information Input Validation ensures malicious inputs are checked and rejected before processing, mitigating improper neutralization leading to XSS in the WordPress plugin.

SI-2 Flaw Remediation good match
prevent

Flaw Remediation requires timely patching of the vulnerable Mojo Under Construction plugin versions up to 1.1.2 to eliminate the XSS vulnerability.
