Deeper analysis

CVE-2025-25102 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the Yahoo BOSS WordPress plugin developed by Josh Harrison (yahoo-boss package). This issue affects all versions from n/a through <= 0.7. Published on 2025-03-03, it carries a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L).

Remote attackers can exploit this vulnerability over the network with low complexity and no privileges required, though it necessitates user interaction such as clicking a malicious link. Successful exploitation enables reflected XSS, where attacker-controlled input is reflected unsanitized in the web page, allowing script injection in the victim's browser context. The changed scope (S:C) results in low impacts to confidentiality, integrity, and availability, potentially compromising user session data.

The Patchstack advisory at https://patchstack.com/database/Wordpress/Plugin/yahoo-boss/vulnerability/wordpress-yahoo-boss-plugin-0-7-reflected-cross-site-scripting-xss-vulnerability?_s_id=cve documents this reflected XSS vulnerability in the WordPress Yahoo BOSS plugin version 0.7. Security practitioners should consult this reference for additional details on affected installations and recommended mitigations.

MITRE ATT&CK Enterprise TechniquesAI

T1185 Browser Session Hijacking Collection
Adversaries may take advantage of security vulnerabilities and inherent functionality in browser software to change content, modify user-behaviors, and intercept information as part of various browser session hijacking techniques.
T1539 Steal Web Session Cookie Credential Access
An adversary may steal web application or service session cookies and use them to gain access to web applications or Internet services as an authenticated user without needing credentials.
Why these techniques?

Reflected XSS enables script injection in victim's browser context, directly facilitating browser session hijacking (T1185) and stealing web session cookies (T1539) to compromise session data.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

SI-15 mandates filtering information prior to output to web pages, directly preventing reflected XSS by neutralizing unsanitized attacker input during page generation.

prevent

SI-10 requires validation of information inputs, addressing one aspect of the CVE by rejecting or sanitizing malicious payloads before they are reflected.

prevent

SI-2 ensures timely flaw remediation, such as patching the vulnerable Yahoo BOSS WordPress plugin versions <=0.7 to eliminate the XSS vulnerability.
